Spell set I generally use for Reive:
Whirl of Rage
Benthic Typhoon
Quad. Continuum
Delta Thrust
Heavy Strike
Sudden Lunge
Barbed Crescent
Triumphant Roar
Animating Wail
Cocoon
Battery Charge
Magic Fruit
MP Drainkiss
Dream Flower
Actinic Burst
Winds of Promy.
Blazing Bound
Fantod
Mortal Ray
Have been doing /WAR as of late since Whirl of Rage and Actinic Burst are usually adequate to get Dream Flower off and I always have a healer with me, however if you decide to go /RDM for extra safety, solo, or just Stoneskin/Phalanx/Aquaveil, then switch MP Drainkiss out for Empty Thrash to get Double Attack, Convert will cover the loss of MP Drainkiss if you end up running low on MP despite momentum bonuses. If you want to sacrifice some offense, you can swap out Barbed Crescent and Mortal Ray for MP Drainkiss and enough points on top of the two you'd have left anyway to set Chaotic Eye and Zephyr Mantle for Conserve MP depending on how defensive you want to get, otherwise spend the two points on whatever.
