Boss Battler: "Defeat bosses in the Onslaught activity."
How to complete
Onslaught is a wave-based defense of the ADU. Each set of 10 waves ends with a boss wave (the 10th), so survive to wave 10 and kill the boss. Bosses include Claw of the Witness, Fang of the Witness and Lightslayer variants (Fallen Warpriest, Siegehook Ogre, Fieldrazer Tormentor). Spend Scrap on defenses at the start of each set and after waves 3 and 6.
