Soul Siphon (aura, divine, force, necromancy) 30 feet. An astradaemon draws power from the souls of the recently slain. If a Small or larger living creature dies within its aura, the astradaemon gains 5 temporary Hit Points and a +1 status bonus to attack and damage rolls for 1 round, unless the creature was slain by an astradaemon's Devour Soul ability. Incorporeal undead and living spirits traveling outside the body take 1d8 force damage each round within the daemon's aura from the spiritual pressure as the astradaemon pulls in fragments of their soul.

Displacement (divine, illusion, visual) An astradaemon bends light, appearing shifted from its true position, though still in the same space. Creatures targeting the astradaemon must attempt a DC 11 flat check, as if the astradaemon were hidden, even though it remains observed. s such as the Blind-Fight feat and halfling's keen eyes that apply on the flat check against hidden creatures also apply against a displaced astradaemon.

Essence Drain (divine, necromancy, negative) When an astradaemon hits with its claw, jaws, or tail, it drains the target's spiritual and vital essences. The target takes 2d10 negative damage and the astradaemon regains an equal number of Hit Points. The target must succeed at a DC 37 Fortitude save or become doomed 1 and drained 1. If the target was already drained or doomed, it instead increases both conditions' values by 1, to a maximum of 4.

Mortal Shell [>>] (divine, necromancy) Requirements The astradaemon has killed a Large or smaller creature with Overtake; Effect Soul within the past 24 hours and that creature is within the daemon's reach; The astradaemon takes over and wears the body of their victim. This automatically creates a disguise to allow the astradaemon to Impersonate the target creature. The body has a number of Hit Points equal to 3 times the level of the creature. Any damage targeting the astradaemon damages the body first. Once the body is reduced to 0 Hit Points, it's destroyed and forces the astradaemon out, back to the daemon's normal form. If the astradaemon takes any good damage while wearing the body, the damage is dealt to the astradaemon directly and it must succeed at a DC 5 flat check or be forced out of the body. Additionally, disjunction and dispel magic can force the astradaemon out of the body with a successful counteract check against DC 41. While wearing the disguise, the astradaemon's attacks use the reach of the body it inhabits, and its size changes to match that of the creature whose soul it consumed. Additionally, the astradaemon is clumsy 2 and enfeebled 4 while wearing the disguise. (These penalties haven't been incorporated into this stat block.)

Overtake Soul [>] (death, divine, incapacitation, necromancy) Requirements The astradaemon hasn't used an action with the attack trait yet this turn; Effect The astradaemon draws out and consumes the soul of a living creature it has grabbed. The creature must succeed at a DC 39 Fortitude save or instantly die. If it dies, the astradaemon gains 10 temporary Hit Points. A creature that survives is temporarily immune for 1 minute.
