The Legend Of Vox Machina Episode 16

Zahra released a monster from her locket, planning to incapacitate the members of Vox Machina to retrieve a vestige. As they fight, the monster turned Grog, Percy and Keyleth into stone. Kash refused to let this go on and join Vox Machina in fighting the monster, causing Zahra to also try and save him by returning the monster into the locket but it attacked Zahra from behind, also turning her to stone. It then proceeded to also turn Scanlan, Pike, Trinket and Vex into stone. The vestige then granted Vax with newfound powers to defeat the monster while Kash healed everyone's petrification.
