Well... It's just something I noticed, but Chaos Power seems to be giving +0-5/+0-5 (May even be +1-5/+1-5) now, anyone able to confirm this?
I'm unsure about the mutant stats, but I believe that's also +0-5/+0-5 as well.
Screenie:
Stage 1-
Stage 2-
I Chaos Power'd the Werewolves on the top and bottom row, and you can see that the bottom one got +2/+5. A few of the others confirm that the minimum is still 0, however. Of course, it could be +0-4/+0-5. Haven't seen a +5 attack yet.
Hope this helps the general population.
