Ember roc

An ember roc is a variant of the standard roc, created by Matthew Mercer.

Creature Information
Ember rocs are giant, fiery, birds presumed to originate from the Fire Plane; Vex noticed one flying above the City of Brass.

Vox Machina soon afterward fought an ember roc during the battle at Fort Daxio, where it was being used as a mount by a fire giant. After its master dismounted, the ember roc joined the battle as well, but was eventually slain by Grog.

Abilities
Due to their fiery nature, ember rocs are immune to fire damage. Just being close to the ember roc causes fire damage; in addition, they have a rechargeable ability called Inferno which more heavily burns nearby enemies in certain radius and pushes them back. They also have normal multiattack consisting of one bite and two claw attacks.
