Resolved Power Surge(?)

[Foxtrox]

I must've missed an Umbrella, though I don't recall her at all

 

[Lunix Vandal]

I'm unsure if I just missed a buff or is it a bug.
When I fight Robo Fortune, every I think 10 seconds I just lose a huge chunk of health. I do NOT use blockbuster, and sometimes it happens, sometimes not. Pretty sure it's not specific to a variant.

What other fighters are on the opponent's team when you see this happen? Wunderkind Umbrella's Signature Ability inflicts damage when your fighter reaches 3 stacks of Power Surge (even if Umbrella is off-field), making her a common pairing with Robo-Fortune's DDOS Marquee Ability. (Extra spicy: doing this during Annie's Diamond-rank Prize Fight, which inflicts extra stacks of Power Surge on top of the DDOS and applies Stun on reaching 5 stacks.)
