I use the PerfZing +PsiDam proc in Radiation Therapy, along with 3 Touch of the Nictus, and 2 Oblits. I just use the base slot in taunt the power. Anything you like. But I use Mocking Beratement Taunt, Recharge, Range, that I bumped up to max +5 levels.
I use no other Taunt sets.
I slotted Ground Zero for DefDebuff, Recharge, and Damage. I also put an Achilles Heel proc in there.
