Path of Exile

To obtain this achievement you need to kill all Warband leaders and they spawn on high-tier maps.

Any time you spawn a map below, you have chance to spawn any of the leaders that can spawn on that map. I believe each boss is limited to 2 per map. I suggest copying the list below to a word document and a you kill each boss variant you delete it so you know when you are done with a map.

Shipyard (T12) - Lightening based bosses
- Musky "Two-Eyes" Grenn
- Susara, Siren of Pondium
- Lussi "Rotmother" Roth


Beacon (T13) - Fire based bosses
- Uruk Baleh
- El'Albin, Bloodeater
- Leli Goya, Daughter of Ash
- Bin'aia, Crimson Rain


Sulfur Wastes (T13) - Cold based bosses
- Yorishi, Aurora-sage
- Jeinei Yuushu
- Otesha, the Giantslayer


Overgrown Ruin (T15) - Chaos based bosses
- Rama, The Kingslayer
- Kalria, The Risen / Kalria, The Fallen (not sure if you need to kill both variations of this)
- Invari, The Bloodshaper
- Lokan, The Deceiver
- Marchek, The Betrayer
- Berrots, The Breaker
- Vessider, The Unrivaled
- Morgrants, The Defeaning
