Death Coil - Fires a projectile at a target unit. If the target is Undead and allied, it heals that target. If the target is non-Undead (i.e. alive) and an enemy, it damages that target for an amount equal to half of what the heal would be.
Death Pact - Sacrifices an allied unit to heal yourself by an amount based on the unit's life. It is possible to modify the spell such that it leaves the unit alive. It is also possible to make this spell heal a % of your life, and also possible to have it restore your mana as well.
Unholy Aura - Increases the movement speed and life regeneration of nearby friendly units.
Animate Dead - Raises dead units in an area around the caster to fight for him. Units can be invulnerable. Or not.
Frost Nova - Deals damage in an area around the target. Also slows unit in that area. Generally, it deals damage to the target, and then deals damage to an area around the target (i.e. it damages the target twice).

Dark Ritual - Sacrifices an allied unit to restore your mana by an amount based on the unit's life. It is possible to modify the spell such that it leaves the unit alive. It is also possible to have this spell restore your life, and to have either/both amounts restored become a % of your health instead.

Vampiric Aura - Melee units affected by this aura will drain back a portion of the damage they deal, to be converted to health. This ability is not allowed.
Carrion Swarm - Does damage in a line. Cone effect. (Skills with a cone effect start with a small AoE but end up with large splash at the last bit.)
Sleep - Forces a unit to fall asleep for a certain period of time. The unit is invulnerable for a short period of time after it falls asleep. After that, you may attack the unit to wake it up.
Inferno - Does splash damage in an area upon impact, stunning any affected units. Also summons a unit there. You can make it such that a unit isn't spawned. Thus this could be a good targeted AoE damage spell.
