I tried to see if this was answered already, but it doesnt appear so; When fighting Omnitron he will have multiple devices out that say ‘Remove from play when Omnitron takes ‘x’ damage’.
So, if two devices are in play that each take 7 damage to Omnitron to remove from play, would they both go away after dealing 7 damage, or would you have to do 14 damage to remove both of them?
It would be 7 and both go away, and it’s within a single round, so all in one go starting with the villian turn ending with the environment turn.
Thanks!
A related question that we encountered recently, when the heroes have accumulated 7 or more damage to Omnitron, does the components such as Electro-Magnetic Railgun get destroyed immediately? Or only at the end of the round (i.e. after the End of Environment phase)?
This affects whether Interpolation Beam continues to make heroes take damage for drawing cards or not.
Given the wording on the card, they would be destroyed the moment 7 or more accumulative damage had occured.
Seconded! TheJayMann is totally correct in his answers here 
Thanks, TheJayMann.
