You could make a new talent that gives the following trigger on all melee, and/or magical attacks:
Suit of choice(I feel crows would probably be the best fit) : After succeeding, increase the value of the target's Crazy condition by +1.
Alternatively, it could be a Manifested Power against the target's Willpower and increases the value of the target's Crazy condition by +1 and an additional +1 per Margin of Success.
From there, you could make Manifested Powers that use the enemy's Crazy condition:
Reduce the Crazy condition of each target in Pulse 4 by -1 and heal by the total value reduced.
Deal a 1/2/3 magical attack, reduce the Crazy condition of the target by -X and add +X to the damage dealt.
Those are just examples, obviously; Target Numbers, ranges, and damage values would need to be tested, but I don't think those kinds of abilities would be game-breaking. Honestly, there's a lot of potential there. You could easily make a whole custom Pursuit out of it.
