On click six, Carnage has Massacres are my Specialty where he can use plasticity, steal energy, and flurry. He also has Symbiote Blade, which was established to replace his damage for both attacks in his flurry if he chooses to use it.

But what happens if he is on click six, uses flurry and steal energy, and also decides to use Symbiote Blade? Let' say that he rolls a 6, just to plug a number in there.
Click 5 still has Massacres are my Specialty, so the second attack will be fine, but it doesn't have Symbiote Blade. Is his damage still replaced, even though he lost the source of replacement?

Thanks.

I wondered the same thing. Personally i think no but i'm not sure.

Yes, it would still be replaced because of the wording of Symbiote Blade, it says he damage becomes locked, locked values stay until the action is over in which it became locked. Flurry is one action that gives 2 attacks, so even if Symbiote Blade is no longer there, the locked value would remain.

I agree with Blaiser. I don't see anywhere that it would go away, other than the precendent set by just about every other thing that goes away. But all of those (barrier, outwit, perplex) specify that the effect ends if the power is no longer there. This seems to lock it in and doesn't go away until Carnage gets done doing his thing.

But I would like to see something more official, or at least a decent concensus.

BN, page 15:

Whenever a power or combat ability is countered, or lost because it no longer appears in the stat slot on a character, all game effects generated by that power or ability immediately end, but any tokens placed on character cards (or feats) as a result of the countered power or ability remain there.

Hmm. I was right. I knew about this rule, i just wasn't sure how far it extended.
