Shock: Damages enemies with an electrical blast. The area effect attack sends a wave of electricity. The more powerful versions of shock can leave enemies convulsing for several seconds. Do enough damage and all that is left is a smoldering skeleton.
Inferno: Play with fire with either a single fireball thrown at an enemy or by creating a ring of fire to burn multiple enemies. The environment won't catch fire, but enemies will.
Time Control: The targeted and area effect versions of this power are vastly different. Targeting an enemy and using time control lets you dash behind them, leaving your opponent open for a strike. If you don't target an enemy, Time Control slows time for everyone around you. This is one of the most useful spells in your grimoire. The higher the level, the longer and more pronounced the effect.
Blades: Calls forth mystical blades to cut through your enemy. This is especially useful for targets running away, as the blades will track them down.
Vortex: Creates a powerful whirlwind that snatches up enemies and tosses them about. You'll do greater damage by targeting a single enemy, but it's more fun to send a whole room flying about.
Chaos: Summons the Mask of Madness to befuddle enemies. Confused enemies may attack their friend or even drop to scrub the floor (gotta get those bloodstains out). Targeted attacks extend the effect.
Force Push: Use an area effect attack to create a wall of energy around you, pushing back all nearby foes and giving you some breathing room. Or target a single enemy to knock them back. This is very useful when fighting near cliffs and ledges.
Raise Dead: Call forth the dead to fight as your allies. If cast near recently killed enemies, their spirits will rise to fight for you. Otherwise you get some less-impressive spirits. Use this spell when battling Balverines to even the playing field. Though this seems like a dark art, you don't become corrupt or evil by using this spell.
