The creature treats its saving throws with the associated save as one degree of success better than it rolled. This is not cumulative with other effects that change their degree of success, like the incapacitation trait (except for rolling a natural 1 or 20). Each time the monster gains mythic resilience, choose one save. The ability should apply to the creature's highest saves first.
Trinity Star(arcane)
When Dream Aethusa dies, a field of iridescent energy envelops her lifeless body (and her gear) for 10 minutes. During this time, any creature that touches Dream Aethusa's body takes 9d6 force damage (DC 37 basic Reflex save). After 10 minutes have passed, Aethusa's body rises into the air and is consumed by mythic energy, transforming into the Trinity Star hazard.
The creature has a pool of 3 Mythic Points, and can spend those Mythic Points for any of the actions it has.

Recharge(concentrate)

Remove a Condition(concentrate)

Steady Spellcasting
