Phylactery

Spawner · Trains 1× Lich / wave

Trains Lich - the undead's kitchen-sink caster. Knows Frost Nova (burst AOE + chill), Death and Decay (channeled AOE), and Bone Armor (self-buff). Most ability-dense unit in the game, but mana-starved - it can't cast everything every fight.

When the cold reaches you, it has already chosen which bones to take first.
