Gunslinger Build (Lv. 10-200)

Cooling Effect has a higher damage percentage than Fake Shot (you'll want to incapacitate them somehow) and also applies extra elemental damage while freezing. At the rate you'll be killing monsters in that level range with Triple Fire, the extra damage from Cooling Effect will more than likely be more helpful than a slow attacking Octopus or an every now and then Gaviota.
