Although I use it on all 3 characters, it's most effective when used with a sunsinger, firebolt nades, and a helmet that boosts your super for grenade kills. Also make sure intellect and discipline are as close to maxed as possible (or I suppose you could use Voidfang with lower disc). This usually nets me a good amount of supers, and since people pull special and don't wait for people, this ensures I'll almost always have ammo. EDIT: I've also used Her Benevolence with Mulligan and Performance Bonus, but I didn't find it that much better.
