Once per ingame day for hint? Or real time day?

I have basically gotten two possible hints and they don't seem to reference to the current 'drop' list that is on the wiki.

1) Sea or Forest, with the sea means fishing (fishing ship, or fishing at sea?) but she didn't expand on that. With the forest, she specified the 'tree' that protects the dungeon, which is likely Fidoh, but the reward someone posted on the wiki is Coil.

2) She mentions 'rascals' and how they were harmless yet actually holding a lot of power (imps or some type of fomor?), she says they can be also found on 'gigantic' monsters, the ones who grew to massive size by absorbing the game's sun, and two moons.

1) References the 'tree' that protects the dungeon in the coill abyss dungeon... AKA Sephirot. Not sure what the sea meant, but the forests definitely suggest Coill and/or Foidh. The reference to Sephirot makes it clear though which dungeon she's talking about.

2) She mentions the succubus fiends in Rabbie Phantasm, calling them rascals cause, well, they are in Phantasm. And the 'gigantic monsters' reference refers to how ancient monsters are ginormous/big/thicc when compared to non-ancient mobs of the same type.

These hints clearly hint at the places they drop, it just takes large amounts of knowledge of the mobs/places in Mabinogi. :/ The rest of the hints I didn't view but I'm very sure they hint at the drops in the tables. In response to the title, I think it's only once per real day; I could be completely wrong. (Can't check anymore since I have the skill already)

I believe it is, in fact, once per real-time day. I tried to ask for another hint several hours later in real-time (which would equate to multiple Erinn days) and she said to ask again tomorrow (or something to that effect).
