Blackjaw, The Remnant

Blackjaw, The Remnant, is a whirlwind of destruction who pushes players to balance offense with defense under nonstop pressure. His lightning-fast movements and unpredictable attacks make it nearly impossible to relax, even for a moment.

Adding to the chaos, Blackjaw summons spirit minions that pursue players and disrupt movement. These summons are not just a nuisance—they hit hard and can throw off your rhythm in an already intense encounter.

Beating Blackjaw demands constant motion, precise aim, and the ability to multitask effectively. Clearing his minions while avoiding his direct attacks is no small feat. As a boss, Blackjaw delivers one of the most dynamic and reactive fights in Path of Exile 2.

The arena is often filled with poisonous clouds, and with Jamanra’s ground-pounding AoE attacks, players must constantly move or risk getting overwhelmed. This constant pressure is what elevates Jamanra to one of the hardest boss in PoE2 fights.

To come out on top, you’ll need to rely on quick footwork, solid poison resistance, and the ability to consistently deal damage without staying still for too long. Jamanra punishes hesitation and demands full focus from start to finish.

Xesht, We That Are One
