Just an idea for an MP resource management tank that uses cloth. Probably has a "magic dagger" or something as a weapon.

Example skills:
Lvl 1: Firey Thrust -Delivers 150 potency attack at cost of X mana.
Lvl 2: Enfrost - Regular attacks regen mana and deal X potency extra damage (less than Enfire)
Lvl 4: Ice Sickle - Delivers 120 potency attack and regens X mana. (combo to do 170 potency w/Firey Thrust)
Lvl 6: Enfire - Increase enmity and deal X potency extra damage at the cost of mana per second.
Lvl 8: Thunder Spikes - Whenever an enemy deals damage to you, they take X potency damage for over X seconds and increases armour by X. (mana)
Lvl 12: Chain Lightning - Increases enmity and applies a low-damage DoT (mana)
Lvl 15: Fireball - Deals ranged 130 potency damage and increases enmity (mana)
Lvl 18: Shock - Deals X damage and stuns
Lvl 22: Thunderous Blade - Deliver 240 potency attack (combo with Ice Sickle) and applies low level dot, increases enmity
....etc
