The info for the Ritch Flamespitter reads:
info = function(self, t)
return ([[Conjures up a bolt of fire doing %0.2f fire damage.
The damage will increase with the Magic stat]]):format(damDesc(self, DamageType.FIRE, self:combatTalentSpellDamage(t, 8, 120)))
end
, while the actual ability does:
self:project(tg, x, y, DamageType.FIRE, self:mindCrit(self:combatTalentMindDamage(t, 8, 120)), {type="flame"})
So, the ability actually uses WIL, rather than MAG, which is consistent with all the other Wild Gifts.
