This trait is honestly pretty nice. I'm liking it a lot, but getting 1 stack of might as an option when you could have had Aegis, Protection (both good defensive boons), Regeneration (synergy with rest of Chaos line), or Swiftness just feels bad. I think one of the following changes is warranted
Remove might from the trait altogether
Each pulse gives 1 stack of might for 5s and one of the other current boons at random
Increase the number of stacks of might given each time it's applied by this trait
2 would be a flat buff, so I understand why that's not likely. However, it would better suit the ambush play-style that the increased stealth duration seems to encourage. But I would rather might just be gone from the trait rather than have it reduce my survivability since I didn't get one of the other boons.
