Is steal energy optional?
e.g. can Parasite choose not to use it to get back onto poision?

Also i am making a figure of Omega red, i was wondering
how would flurry work if i was to have energy steal on the same part of the dial.

Assuming Omega hits twice, once getting him a click of energy back, and on that part of the dial flurry is NOT shown, would he get the second attack?

No.


Should it be?

Every sane person would think so.

Parasite,
no good.

Could Whiz Kids fix this.
Yes.


But
why
should
they?


(it would only make the game better)

(and why use the internet for something useful?)

No, he wouldn't. Resolution of the (first) attack includes dealing damage to the character (such as from a critical miss) or healing the character (such as Steal Energy). If after resolution of the first attack the character no longer has Flurry, they cannot make the second attack.
