Barracoon the Piper

When Barracoon is defeated, it rewards Champion Tokens and the Skull of Greed.

Each champion rewards a different skull, all six are required to summon The Harrower.

Location

The Barracoon altar can be found on the fourth level of the Despise dungeon.

Activation

A champ spawn can be activated by using the Valor virtue, but it can also start just by walking near the altar, since there's a random chance the champ will activate on its own.

Vermin Horde Spawn

Once the altar is active, the first wave of monsters begins. Each champion spawn progresses through four tiers, and clearing all four will summon the champion boss.

Tier 1
Giant Rat	Slime

Tier 2
Ratman	Dire Wolf

Tier 3
Ratman Mage	Hell Hound

Tier 4
Ratman Archer	Silver Serpent
