Assimilated Demolisher

Overview

The Assimilated Demolisher is a secret Vex miniboss in the Echoes Battlegrounds. Each Battleground mission has a closed portal hidden in a random location. Using a Torch Hammer to open it summons the Demolisher, which has a yellow health bar.

Defeating the Demolisher drops a summoning beacon for a World boss. Summoning the secret bosses is tied to the Demo Squad triumph, and the upgraded Torch Hammer requires the NES006 quest and the A Rising Chorus questline.
