Secret Art: Bloody Ritual

You create a blood tether to all enemies within range, causing them to be Slowed. The tether lasts until the start of your next turn or until they move out of the range of this ability.

At the start of your next turn, the tethers explode, dealing Heavy damage to all tethered enemies as it sucks the life energy from them. For every enemy dealt damage with this ability, you recover 1 Mana or 5 HP (your choice). If an enemy dies while under the effect of the tether but before it explodes, you also gain this regeneration effect.
