Fire II

[Zantusken]

If you have all Astral Fire and Umbral Ice stacks ready, you can combo 2 Fire II casts followed by 2 Flare casts (i usually keep swiftcast for the double flare) for some great AoE dmg, bonus points if you also use sharpcast beforehand for thunder IV, but that combo is mainly used on large Dungeon pulls, since Fire II is in my book only worth using when you fight 4 or more enemies at once.

Fire II is a DPS loss. It is better to just spam flare(using it to go from UI back to AF). Fire II is basically never useful at any level which is the problem.
