Berserker:
* Battle Boast: Makes a disheartening boast at enemies to lower their attack and armor but increase their movespeed. Increases with number of enemies killed, manacost lowers with level.
* The Bigger They Are: Selects a single enemy. While active, every attack made on the selected unit does additional damage based on its armor (i.e. 2 armor does 2/10/20 damage, 5 armor does 5/25/50, etc.).
* Fury: Increases attack and move speed, but reduces spell resistance and armor (increase/decrease with level).
* Rampage: Loses all control and attacks everything in sight, with increased damage, spell resistance, armor, splash damage aginst both allies and enemies.
Blood Mage: Caster with direct attacks. Not sure what you mean. A melee spellcaster?
Priest:
* Blessing: Heals target for a large amount, surrounding allies are healed for a smaller amount.
* Holy Zeal: Target gains increased attack speed, and deals extra damage to demonic enemies.
* Way of Peace: All targets in area lose the ability to attack for a short time (must contain both allied and enemy units to work).
* Divine Protection: Heals all allies, removes negative buffs, adds positive buffs.
Ranger:
* Trick Shot: Arrow bounces off 1/2/3 additional enemies, doing reduced damage to each.
* Snipe: Gains increased damage and range at the cost of lowered move and attack speed.
* Weak Spot: Can find weak spots in enemy armor, dealing increased damage.
* Phantom Arrows, Fly!:
This.
Necromancer:
* Death from Life: Heals the Necromancer and his minions, dealing the same amount of damage to surrounding enemies, increases with level.
* Animate Corpse: Creates a random Skeletal Minion from a corpse (Warrior, Archer, Mage, Grunt), in greater numbers and power with level.
* Entropy: Target enemy is slowed and takes % damage. If it dies while under this spell, all surrounding units have a weaker version of Entropy cast on them.
* Grand Conjuration: Fuses all skeletal minions in an area into a Skeletal Aberration. The Aberration's health depends on the number of skeletons used to summon it (if only one skeleton, has health in the red. If all skeletons, has full health and some buffs).
Assassin:
* Hide: Moves and casts invisibly, but attacking makes the assassin visible.
* Patient Strike: Channels for a few seconds, then deals high damage to the unit in a small area in front of the assassin. If there is no unit to damage, the attack is wasted.
* Marked For Death: Stabs the target with a special poisoned blade that greatly reduces armor and spell resistance.
* Trance: The assassin enters a murderous trance that gives him greatly improved reflexes but decreased survivability. While active, has greatly reduced armor, very high evasion, and very high bonus damage.
