Traits

Ashen Rebirth (1/Day). When reduced to 0 hit points, Phenex becomes an ember in its space with AC 15 and 30 hit points, immune to fire and poison damage. It retains its initiative and saving throws, but cannot move or take actions, bonus actions, reactions or legendary actions. At the end of its next turn, if the ember has more than 0 hit points, Phenex reforms there with 80 hit points. If the ember reaches 0 hit points, Phenex dies and does not reform. Rebirth does not restore spent Legendary Resistance uses or automatically recharge its breath.

Legendary Resistance (2/Day). If Phenex fails a saving throw, it can choose to succeed instead.
