The following happened to me during the second run of the sinister six event. The alliance was at round 7. The boss node was Carnage, Doc Ock and Venom. I finish off Doc Ock with a match. Venom comes in and creates 3 invisibility tiles whereas his ability states that he will only create 2.
I believe at higher rounds he creates more; have you re-read the description for the current round?
Yeah, he makes one per turn in the early rounds, then 2 per turn, and finally 3 per turn.
I know he creates more at higher levels. That’s why I explicitly stated what his ability showed.
Hmm, he did mention Round 7 as well. I believe 2 per turn is the round 7 rank.
