After some thinking.
4K per Increment would be quite a good increase, not too high, not too low. But somewhere in the middle. It's a passive buff which triggers off hits.
I would like to think it would benefit and work on actually making the Dragon AA Tree Relevant again.
Would love for this to be moved to the Poll Caith.
Probably won't get a lot of votes due to it effecting an assassin but would definitely love to see it up there.
