Scanlan Shorthalt used a Gate spell scroll to summon Yenk to the ruins of Draconia to use as bait for Vorugal. Scanlan used a successful Dominate Monster spell to convince the fiend to challenge the dragon and Vox Machina hoped for one of them to kill the other. However, after several rounds of fighting Yenk managed to shake off the spell and take a swing at Percy, causing Vox Machina to join in the battle. Grog eventually landed the final blow on Yenk as the fiend did a jumping kick at his head. The goliath grabbed him by the legs and slowly tore him in two. Once the battle had ended, the Spire of Conflux was retrieved from the goristro's eviscerated stomach and given to Keyleth.
