A lot of the ideas in this thread are pretty cool but I'm surprised no-one has mentioned Rikti yet, they would make an awesome psi-dmg mastermind set.
Here would be a possible setup:
Psionic Dart 1 - Ranged, Moderate DMG(Psionic), Foe -Recharge
Summon Rikti Monkeys 1 - Summon Rikti Monkeys
Mental Blast 2 - Ranged, High DMG(Psionic), Foe -Recharge
Mental Clarity 6 - Ranged, Focus Rikti Henchmen
Psychic Scream 8 - Ranged (Cone), High DMG(Psionic), Foe -Recharge
Summon Headman Gunmen 12 - Summon Headman Gunmen
Happy Thoughts 18 - Buff Rikti +Damage, +Resistance, +To Hit, +Recovery
Summon Chief Mentalist 26 - Summon Chief Mentalist
Words of Encouragement 32 - Ranged, Empower Rikti Henchmen
The Lore behind this set would be pretty easy to come up with saying that the Rikti Traditionalists, although abhorring violence, have begun to join some psychic heroes/villains in hopes of proving their commitment to peace with Primal Earthlings and gaining their trust.(or something like that)
