Key Points

His 1st ability steals enemy Strength.
His 3rd ability, the tombstone, is also strong: it spawns zombies on enemies within its range. (To deal with it, destroy the tombstone, or move out of its range and kill the zombies.)
His 2nd ability drains HP from nearby enemies to heal him.
Landing his 1st ability while slowing enemies down with his 3rd is strong.
