Please give us back Darkside MP eating mechanic

[Duelle]

- Dark passenger is worthless

I can think if three ways to fix this.

- Increase damage to something like 200 potency, but lock the ability behind DA.
- Change the DA effect into a 5-second stun.
- Change the DA effect into a mitigation effect that reduces damage taken by you for 10 seconds.

The first would make it worthwhile when dealing with multiple mobs. The second would do something similar and be nice to have in dungeons or dealing with adds (assuming they can be stunned). The third helps a bit with mitigation.
