Hey guys!

This is basically the same thing except the cooldown, so if you need those heals and debuff removals in round 1 right away Y mystery would be your choice

I would go with the chaos Y standard because she is a support ninja

Nothing special here honestly, this one isn't really necessary

This one is a good supporting one of course

+2 is interesting and can be combined with the +2 standard making her some kind of a healer/dps

You can try that for some fun builds but generally I would recommend just keeping her as a pure support so either +2 or Y are viable in this case but Y is the safer option especially vs big damage enemies

Breakthrough priority:

Passive 1,2 > Mystery > Standard > Chase
