Terrify (T8) does good AoE damage while being Mind's "every encounter" power. There are 2 problems with Terrify though. 1. Mass Hypnosis is your only reliable way of setting up Containment for it and 2. Terrify doesn't set up containment for the rest of the fight.
I haven't played him since before Page 5, so my tactic will likely change, but my Mind/FF used to start every fight with this combo
Mass Hypnosis->Terrify->Repulsion Bomb.
With the FF changes, I suspect the new start should be
Force Bomb->Mass Hypnosis-> Terrify
The reason for this change is that Force Bomb now has -Res to it, however, since the damage got lowered, you want to use this before MH so you don't waste the Containment potential of Terrify (which I slot with Dam/Mez HOs).
