Algea
Level 11Abilities
Lifesense allows a monster to sense the vital essence of living and undead creatures within the listed range. The sense can distinguish between the vitality energy animating living creatures and the void energy animating undead creatures, much as sight distinguishes colors.
An algea can see magic auras on creatures or objects that it can observe; it can't see magic auras on creatures or objects that are hidden from its view. It learns the schools of magic for all spells affecting creatures.
30 feet. A creature that begins its turn in the aura must attempt a DC 27 will save. Undead take a -2 circumstance penalty to this saving throw. The creature is then temporarily immune to the grieving aura for 1 hour. Success The creature is unaffected. Failure For 1 round, the creature can't use reactions and is Slowed 1 for that turn as it sobs uncontrollably. Critical Failure As failure, but the effects lasts while the creature remains in the aura plus 1 minute.
Whenever a creature fails its save against Frenzied Beaks, the algea attempts to counter a spell effect active on that creature (6th level, counteract check +22). The algea can choose which effect to attempt to counteract for each creature.
Each foe in the swarm's space takes 5d6 piercing damage (DC 30 reflex) and is exposed to drain magic. This damage affects incorporeal creatures as if it had the effects of a ghost touch property rune.
An incorporeal undead damaged by Frenzied Beaks must attempt a DC 30 will save. Critical Success The undead is unaffected and is temporarily immune for 24 hours. Success The undead takes a –10-foot status penalty to Speeds for 1 round. Failure As success, but the undead is also Immobilized for 1 round, although it can attempt to Escape (DC 30). Critical Failure The undead is restrained for 1 round. The algea can attempt to plane shift with the Restrained creature even if that creature isn't willing, but an unwilling creature can attempt a Will save to resist Interplanar Teleport. If it succeeds, the algea plane shifts and leaves the incorporeal creature behind, which is then no longer restrained.
Description
Algeas protect (and sometimes retrieve) souls at risk of being claimed by other entities, particularly spellcasters who dabbled with otherworldly forces but never officially pledged their souls.
