I really mean Faery Dragon.Imo Fairy Dragon ( I believe it's what you meant )
This is a small dragon, 2-3 feet long with butterfly like wings, which can be found on mystic forests or other faery land.
They are rather michievous but usualy good creatures.
They are known to be good spell caster.
Their breath weapon is a gaz that provoque comatose. (i don't see how to simulate sleep effect in diablo)
Since it's not a real dragon and has nothing to do with "fairy", we have relative freedom for his choice spells.
I've tried to make it different from other pets, so his lack of aura, etc..
But i think his skills are too close from the classic D2 ones, so more work is needed.
