Bestiary 2 | Monsters | Aeon | Bythos | Special Abilities | Aging Strike
If a bythos strikes a living target with two slam attacks in a single round, the bythos ages the creature, causing it to
advance to the next age category (Pathfinder RPG Core Rulebook 169) if it fails a DC 24 Fortitude save. The victim gains all of the penalties from this aging and none of the bonuses. A venerable victim targeted by this ability dies if it fails a DC 24 Fortitude save. This process is reversible with greater
restoration,
limited wish,
miracle, or wish. The save DC is Constitution-based.
