Jade Winds
Eh, we really don’t need a buff to Jade Winds. It is already a hundred times better than Basilisk Venom, and that’s without a cooldown. If you lower the energy cost even more you run into the risk of people repeatedly stunning multiple foes in rapid chains of Jade Winds.
I see the skill as more of a team enabler of escape than a straight up duel skill, but I reckon it could be powerful even in those scenarios if you were patient and pooled some energy before going at it!
