Will this help with life skills too or is it just for alchemy? --Jacobpaige 04:32, 21 April 2009 (UTC)

Yeah, the rain also boosts the success of life skills and alchemy crystal-making. --Iyasenu 06:59, 29 March 2010 (UTC)


In what way does it help with Farming? I tried casting one on my farm but it did not change the water value--Leyuu 15:32, 30 June 2010 (UTC)

Final Hit

If you use rank 1 rain casting around the sun mark, is it possible for a glowing twin sword statue to appear? Just curious. Also, is the lightning affect much like the thunderstorms, or is it actual lightning as an attack, such as thunder?Novaix 09:35, 2 September 2009 (UTC)

The lightning CAN be used to attack but from what I've read, the damage is too low to make much use out of using it offensively. --Iyasenu 06:59, 29 March 2010 (UTC)

Cloud Making

I got bored one day (today) and went through the skillinfo.xml, and found a skill called "Cloud Making". It's probably reaaaaallllllyyyyyyyyyy outdated, but is it a separate skill? Because there is obviously a link between clouds and rain (I could be wrong, but in real life, it's kinda hard to have like.. a heavy downpour without any sight of clouds). Are they/could they be the same skill? (They = "Cloud Making" and this skill, Rain Casting)--Яειм 's Talk 17:04, 28 November 2009 (UTC)

skill_leveldetail.xml matches "Cloud Making" with the same skill details as on this page, and "Rain Casting" in the korean version of skillinfo.xml has the same skill ID as "Cloud Making" in the NA version, so odds are that both are the same skill. --Duet 00:18, 29 November 2009 (UTC)
If that's the case, we better change the title of this article to Cloud Making. All of the Alchemy skill names are being changed to what is found in the skillinfo.xml
Thundercross 21:41, 17 January 2010 (UTC)
You're not quite right on that point. The names in skillinfo.xml are internal names, they're not names that are seen in game. For example, Desynthesis is still listed as Fragmentation and, as a more current example, Wind Guard still has the old Windbreaker name. The actual localized names are in a different file altogether, and it's those translations that are being used for the article pages, when available. --Duet 22:51, 17 January 2010 (UTC)


It costs so much to get to rank 1, along with being almost non-offensive with a buffing trait, yet it doesn't seam to do anything beyond adding a few success points to life skills and damage to a specific skill. It devours a huge amount of stamina, it doesn't seam reasonable that this skill is all that is posted. Maybe the +20% water damage with a team of Water Blasting Alchemists makes it worth the unbelievable AP cost? This skill has me puzzled on so many levels.--Tricky B Bomb (Talk) 13:22, 11 December 2009 (UTC)

I have a few likely reasons why it costs so much:

Combined with a team of Water Blast users as you suggest with it's 20% percent boost of damage plus rank 1 Alchemy Mastery's 45 percent boost and Water Blast's stacked damage can do a great amount of damage, for a skill that isnt influeced by any stat in terms of damage.

It's a skill that also gives more stamina(probably to help with that insane stamina cost), which is always welcomed though the AP is alittle high for that alone

And the ability to make it rain anywhere, as you please is a great asset to life skillers. Those are my two cents as to why it's so AP costly. This rain apparantly helps with farming according to the info so it'll make you money if that's the case.

Speaking of the damage boost, how would Water Blast's stacked charges influence it's damage? I wonder if it's like firebolt's 6.5x damage increase for 5 charges? --Bryanneo 14:51, 11 January 2010 (UTC)

Now that i look at it, the duration is pretty low for the stamina you pay to cast it. --Bryanneo 15:32, 11 January 2010 (UTC)

You can always use cylinders upgraded for stamina use reduction. I wonder if this alchemy skill gets a boost from being used with a Water Cylinder. --Iyasenu 06:59, 29 March 2010 (UTC)

Perhaps since it is (or should be) a water based skill, you can get around 35% stamina reduction on a cylinder plus 20% from a stamina reduction set to help battle the massive cost of stamina. --Bryanneo 14:29, 1 April 2010 (UTC)

Well, let's talk theoretical. Let's assume a player has r1 Water Cannon, r1 Alchemy Mastery, r1 Critical Hit, and r1 Rain Casting okay? No enchants to boost damage or Alchemy-based titles and the enemy has 0 defense and 0% protection. Now, let's just assume the 4 skills get to play with Water Cannon's maximum damage at 5 charges.
  • Rank 1 WC full charge (6.5x), Alchemy Mastery (+0.45%), Critical Hit (150%), Rain Casting (0.20%) = final number...
  • So... 136 x 6.5 = 884 + (0.45% x 884) = 1,281.8 + (150% x 1,281.8) = 3,204.5 + (20% x 3,204.5) = 3,845.4 damage (best condition).
  • If you throw in Water Cylinder (+15%), then 3,845.4 + (15% x 3,845.4) = 4,422.21
So the damage posibility of r1 WC, r1 AM, r1 CH, r1 RC is pretty high (even higher with Water Cylinder). However my math could be wrong and the order could also be wrong. The +20% bonus from raincasting could go to WC directly before alchemy master is taken into account or after alchemy mastery or before critical hit, but whatever the case, we're seeing some -very- high digits. --Miyuna 05:44, 17 April 2010 (UTC)
  • 136 (Water Cannon) x 6.5 (5-Charge) x 1.2 (Rain Casting) x 1.15 (Water Cylinder) x 1.45 (Alchemy Mastery) x 2.5 (Critical Hit) = 4,422.21.
    • When calculating percentages, the order of operations doesn't matter, unless dealing with other forms of mathematics (addition, subtraction, exponents, etc).
      If the x 1.2 from Rain Casting is taken out of that formula, the product becomes 3,685.175. So yes, the difference in having Rain Casting at rank 1 and not having it at all would be a whopping 737 damage. --ZephyreTALK 18:16, 13 September 2010 (UTC)


would enchants or cylinder upgrades affect the lightning damg? if so it could do some damg (32.2-42.55 with the water cylinder up's and 15% extra damg. for water skills(just an estimate))--Sreth 01:47, 16 April 2010 (UTC)

Rain Strength

I was wondering what the chart meant by "Rain Strength". Well, more-so I wondering what the numbers refer to, since on the weather forecaster I use from the Weather page here only go from 0~9 and then to storming. I'd imagine that 20 = storming for this skill. and 0 = just cloudy? --Iyasenu 05:06, 9 May 2010 (UTC)

Yes It's True. 20 = storming and 0 = just cloudy. --Juff 13:16, 9 May 2010 (UTC)
Oh, I just tested and 0 strength rain on the chart is actually rain. xD It's only just clouds and Novice rank. --Iyasenu 06:37, 11 June 2010 (UTC)

stacks with normal rain?

if you have +3 normal rain and +2 rain casting, does that mean +2, +3, or +5 result for your production? -- ladywinter ~{talk | contribs}~ 19:01, 16 May 2010 (UTC)

No, Rain Casting and natural Rain do not stack. Tested by checking the success rate for crystal making at a steam oven, used Rain Casting, and then checked the success rate again. No change post cast. EnigmaticFractal 11:18, 10 June 2010 (UTC)
Actually, it does not stack with just Alchemy skills at the time being it appears, since all levels of rain besides thunder give the same alchemy bonus. With regular life skills at a higher rank, it DOES stack with rain. This was tested with Handicraft and potion making. -Temjin 12:02 am pst 6/16/10

stack damg.

if two people with rain casting r1 used it, and the clouds overlapped would water canon get a +40% boost instead of just +20%. if so maybe thats why it takes so much ap Sreth 01:26, 8 June 2010 (UTC)!

Alchemy Mastery

Does anyone know what effects, if any, Alchemy Mastery has on Rain Casting? I'm hoping it increases the duration, or perhaps the radius of the rain cloud, but I figured I'd ask here in the hopes that someone actually knew. EnigmaticFractal 13:02, 9 June 2010 (UTC)


Can you use rain casting to obtain gems such as rubies that require it to be raining during the day? I know it would be a bad idea to use rain casting on one small spot, but can someone verify if this works?--Th3Evil5Ponge 00:12, 15 August 2010 (UTC)

Fun Fact

Well I'm not sure if you can do this in other indoor locations but, you can create rain clouds in the guild halls :D -- Rainfall - 02:36, 14 August 2010 (UTC)

Rain and enchants.

I've heard from people that Rain Casting can boost the success rate of enchant burning but I haven't been able to check myself. Can anyone confirm this? Tellos 18:37, 14 August 2010 (UTC)

At least it doesn't for rank 1 burning. Ƹ̵̡Ӝ̵̨̄ƷCosmicƸ̵̡Ӝ̵̨̄Ʒ a L k 19:04, 13 September 2010 (UTC)

Increasing natural reserves

Since Rain casting increases the amount of herbs/wool/etc that can be gathered before depleting the resource, does it apply to ores as well? Specifically in Barri as raincasting can't be used in the underground.

Squirel (talk)21:25, 30 May 2015

Allied NPCs affected by No-aggro?

I was in Rescue the Scout, I noticed any of the Guardsmen standing under the cloud did not aggro any of the enemies. Is this normal?

Infodude575 (talk)11:29, 3 January 2015

Effect of Rain on Aggro

I think more research needs to be done on how rain affects aggro.

It appears that rather than prevent aggro, raincasting drastically reduces aggro range. For example, casting rain, and then standing on top of an enemy in Martial Arts Competition WILL cause the enemy to aggro. Creds given to Felyx.

If this is true, I think we need to figure out what the aggro range is, or by what percentage the aggro range is reduced.

Also, it seems that r1 Raincasting's lightning de-aggro effect does not apply immediately. Rather, some monsters will require multiple strikes before they lose aggro. Perhaps this number can be quantified.

Kirbysama (talk)15:28, 18 April 2014

I've definitely noticed the reduced aggro range. Kristell has aggroed me many times after I finished rain casting, to my great annoyance.

Blargel (talk)17:15, 18 April 2014

I have done some preliminary testing on the matter, it seems that from ranks 9 -> 1, the aggro range is reduced to 100cm. This is just within barehand melee range. I need some help confirming, but rank 1 -might- reduce visibility to 50cm. This would be when character models are basically touching. Considering what Raincasting is, I'd explain this effect as "Visibility is reduced in a rain storm, so enemies will have trouble noticing you."

It seems that the "visibility range" might decrease at rank 9, making it more effective, but I haven't yet tested below rank 9.

Also, I have not fully tested the de-aggro ability of the rain, but it seems it requires 3-5 lightning strikes.

Anyone willing to do some more testing and confirm?

Kirbysama (talk)10:52, 19 April 2014

Lightning Strikes

It seems like they're not happening? When I use raincasting in MA, the lightning doesn't seem to do anything at all. It strikes randomly, but doesn't hit any enemies?

Kirbysama (talk)14:03, 31 January 2014

not in range from what I can tell...unless they are directly under it then...I have no idea.

レキシス・ミカヤ (talk)14:06, 31 January 2014

Lightning strikes randomly within the cloud radius, or perhaps slightly smaller. But even for enemies underneath, it didn't hit...

Kirbysama (talk)14:47, 1 February 2014

Quite odd. I'm not really a raincaster, but I do see what you mean when alchs I party with use raincasting.

レキシス・ミカヤ (talk)17:02, 1 February 2014

Forget it. The lightning DOES strike. At least, it does on weak mobs. I haven't tested stronger mobs yet.

However, I noticed the lightning does not reset aggro. Monsters that have aggro'd me, and were hit by lightning continue to aggro, with no re-aggro. It appears it might reset AI rather than aggro. If it reset aggro, then it should be the case that using rain casting would cause a monster to be unable to re-aggro the caster unless attacked. But that is not the case.

Kirbysama (talk)23:05, 2 February 2014

maybe kinda like how golem AI works, you need to target something?

レキシス・ミカヤ (talk)00:10, 3 February 2014

I don't understand what you mean. If you are not targeting anything, lightning will still randomly strike any enemies in cloud radius, and do 1-10 damage not corresponding to the visual lightning striking from the cloud itself.

How does targeting relate to resetting aggro or resetting AI?

Kirbysama (talk)11:10, 3 February 2014

OOps, I was talking about summon GOlem Ai and how it requires you to target something to use skills. Throwing that out the window, I don't see any other oddities with rain casting outside of what you mentioned :x.

レキシス・ミカヤ (talk)14:01, 3 February 2014

So to restate the question here-- does raincasting really reset aggro? I've confirmed that it's true that it prevents aggro from enemies underneath the cloud, until they are attacked, but does the lightning reset aggro when it strikes?

It appears that it resets AI rather than aggro, and I ask that somebody else help me test this.

Kirbysama (talk)15:12, 3 February 2014

Not that I noticed when I'm in MA with people that raincast.

レキシス・ミカヤ (talk)15:14, 3 February 2014

Hillwen Mine

Will it rain or snow when RC is used inside ^?

Infodude575 (talk)10:58, 21 August 2013

Is there a weather bonus cap?

Does using rank 1 RainCasting in a thunderstorm give more production bonus than just thunderstorm or RainCasting alone would? Also, do any cloud bonuses from multiple casters stack?

Sozen Cratos Focker (talk)20:56, 27 May 2013

These have both already been asked on this very page.

Eos367 (talk)04:41, 28 May 2013

Where? I looked through the entire page before posting and again after your reply, I have found no discussions about the first one (cap) and the unanswered one about multiple raincasters is only about the water cannon boost(I'm asking about the production & gathering effects).

Sozen Cratos Focker (talk)04:55, 28 May 2013

It's literally right above where you're talking about;

If searching for "stack" doesn't make it visible try;

Eos367 (talk)10:57, 28 May 2013

Exactly, it's not a threaded discussion. it's at the VERY top

Aubog007 (talk)11:46, 29 May 2013

Up on the very very top.

Aubog007 (talk)05:34, 28 May 2013

There is definitely nothing about this at the very top.

Sozen Cratos Focker (talk)08:08, 28 May 2013

Ok, I've checked the page myself. There used to be a line that stated something along the lines of "Rain Casting does not stack with weather effects". It must have been cut sometime during the rearrangement.
My own personal testing found that so much as "cloudy" would overwrite my R1 rain casting, that is to say, the production effects of rain cast only occur during a clear day.

Rain casting in Homesteads

Friend of mine is ranking the skill and while we were in my homestead, I checked the weather effect and there was a thunderstorm. Sure enough, using the skill in there gave her training for using the skill on a rainy day (as well as experience in pvp for using water cannon under a cloud).

After that training requirement was capped, we left the homestead and reentered, I checked the weather effect in the homestead again and it said it was clear. She went into the homestead but didn't receive experience for using the skill on a clear day.

Do homesteads always have a "clear on a rainy day" effect, or does anyone seem to have more information on training this skill?


Fibbler10:53, 22 June 2012

Look on the homestead page and its talk page, there are hidden weather effects. Only once in a hundred will you actually ever be able to visibly see the rain.

Pyro - (Talk)11:13, 22 June 2012

I wasn't asking about that...I even talked about the weather effect myself...

I'm asking if rain casting can be trained for both "Use during a rainy day" and "Use during a clear day" requirements. My friend used it after I found a thunderstorm in my homestead, using potion making to test the % success rates. That allowed her to train her "Use on a rainy day". After that requirement was finished, I found a clear weather effect(normal success rate %) but that didn't train her "Use on a clear day" requirement.

Fibbler11:19, 22 June 2012

Maybe it wasn't actually clear. What if the homestead's weather was "Cloudy"? Cloudy doesn't add a success rate bonus, similar to clear weather, right?

And if it was cloudy it'd explain both the 0 success bonus and Raincasting not getting any training.

Of course, I'm just guessing.

Iyasenu18:06, 22 June 2012

Nevermind it. But as I understand, Homesteads have two types of weather; Rain or Clear. When it's raining, the production bonus on par with a thunderstorm. When it's clear, there isn't any production bonus. It always shows the weather as "clear" by both the in-game weather forecast and the rain itself will never show up on screen.

I don't know how to explain the test we did any more, but it doesn't matter at this point. My friend has gotten higher rank Rain casting already, so the point is moot.

Fibbler09:53, 4 July 2012

It's a hidden weather effect.

Weather effect outside of Homesteads

  • Changes every 20 minutes.
  • Varies per area, but some areas share the same weather
  • Weather effect can be described from a scale of 1 to 10 (1 being sunny day, 10 being thunderstorm).
  • The increase in production success rate depends on the weather effect.
  • The weather in the surrounding area reflects the forecast.

Weather effect inside of Homesteads

  • Changes every 5 minutes and varies per channel.
    • The change will only take place if you exit and re-enter your Homestead, so you could literally sit there for 5 days without having the weather change.
  • The weather is either sunny or raining (thunderstorm).
  • Homestead weather always appear to be sunny, whether or not the bonus is in effect.

Basically, rain doesn't show up in homesteads, but the effects still occur. That's why your friend got training for rain casting and water cannon.

Cylinders affect Rain Casting Length

Edited by author.
Last edit: 13:18, 13 September 2011

After testing with several of the advanced cylinders. I came out with these results from Rank 4 Raincasting.

Note that it goes:

Name -> Cool Down Time Remaining -> Duration of cloud

Tidal Wave - 38 seconds remaining - 82 Seconds

Earthquake - 41 seconds remaining - 79 Seconds

Hurricane - 37 seconds remaining - 83 seconds

Volcano - 68 seconds remaining - 52 Seconds

Will test further with basic cylinders. Also, the base time using a normal cylinder was still 75 seconds

Kendoza09:11, 13 September 2011

That makes sense considering Rain Casting uses a crystal from all of those elements save fire. My guess (although might be obvious), is that Fire Cylinder will have more time than Volcano, but the other three will have more than fire and volcano but less than Tidal Wave, Earthquake, and Hurricane.

Pyro - (Talk)11:33, 13 September 2011

Does the boost % gained from rain casting increase with each rank, or stay the same through all ranks? Also, does anyone know what the specific Success increase numbers are?

Th3Evil5Ponge15:18, 12 November 2010

The boost to life skills such as weaving and potionmaking changes each rank, as the rain gets stronger. But the boost to alchemy "life" skills such as synthesis and metal conversion stays the same, until rank 1 since they don't check the rain's strength. For them it's either, "Is it raining?" or, "Is it thundering?"

So to answer the question, success rate increases for life skills as you rank it. But doesn't increase for alchemy, until rank 1 (Thundering).--Iyasenu 13:56, 10 January 2011 (PST)

Iyasenu14:56, 10 January 2011

Thanks, that about all I was looking for, but still looking for the exact numbers.
