Oz's Flame Gear after Jump?

I think the 40% damage refers to the damage dealt by the skill the moment you cast it, to any monster near your character. I got no experience using flame gear, but I've used poison mist and I remember it acting as a regular attack the moment you cast it. hitting 1 monster in front of you.

It already does 280% when you cast it post chaos.

Is there a skill table for UA skills post Jump?

I can see the revamped explorer skills post Jump and UA skills post big bang in the Ultimate Skill Tables section but thats about it.
