The corpse star grants the ability to bring others back to life, albeit in a twisted form. The soul’s final moments free of its corporeal fetters are engulfed by blinding, cold light and the stench of rotting flesh, then it rises again bound to a new fate.

You return a dead creature you touch to life, provided that it has been dead no longer than 10 days. The target returns to life with half its hit points, even if it is not willing. It can resist being brought back if it was previously 12th level or is protected by another patron or powerful entity. When a creature is returned in this way, it becomes considered humanoid with the undead subtype regardless of its previous conditions. 

This spell also neutralizes any poisons and cures nonmagical diseases that affected the creature at the time it died. This spell doesn't, however, remove magical diseases, curses, or similar effects; if these aren't first removed prior to casting the spell, they take effect when the creature returns to life. 

Coming back from the dead is an ordeal, even in undeath. The target takes a −4 penalty to all attack rolls, saving throws, and ability checks. Every time the target finishes a long rest, the penalty is reduced by 1 until it disappears.

Creatures raised in this way are loyal and willing to die for the caster and remain so until the raised creature dies again. If the caster dies any creatures raised in this way vanish into dust. (Effect of disintegrate spell.)
