The party first finds him battling Black Gauntlet of Banes and Steel Watchers in the main floor of the foundry. Around his neck is a Kill Collar, which must be disabled by activating a Motivator held by one of the Black Gauntlets.
If the party manages to save him as part of the quest Save the Gondians, he will run out of the lab and gather with the rest of the Gondians outside of the foundry.
Shoot a green arrow that bursts in a spray of acid. Deals 4d4Acid damage immediately and 2d4Acid damage at the end of the target's next turn.
If the spell misses, the target still takes half the initial damage, but no damage at the end of its next turn.
