Confused on metal skeletons..

The notes say that Metal Skeletons switch to archery when hit with icebolt...

And then say that icebolt counter is a good idea.

Does anyone else see why that's problematic?

Ahaha! Its very problematic indeed, perhaps the notes should be revised then! Good Catch! XD

They don't always switch to archery when hit by icebolt, just that they might. That being said, if you see them switch, hit 'em with another icebolt. That should most likely cause them to run at you again with melee (which of course you then load counter).

I say we edit it slightly to have Dante's note in it too?

Done, now it explains it in Basic Information at the top of the page and I also included how effective Fire is against Metal Skeletons (but that's not true for red because of their element).

Fire and ice are equally effective against metal skeletons since they're lightning element. Both are 150% damage, correct?

Yes, Lightning skills do 150% on Fire and Ice enemies and vice versa.
