Traits

Bloodheart Stake.The impaler is magically bound to the ceremonial stake and the sacrificed corpse the ritual caster used to create it. If the impaler is reduced to 0 hit points, it disappears, then re-forms 1d8 hours later in the nearest unoccupied space to the stake and regains all its hit points. The impaler dies only if it is reduced to 0 hit points while either the ceremonial stake is removed from the sacrifice's corpse or the impaler is on a different plane of existence from that corpse.

Legendary Resistance (3/Day).If the impaler fails a saving throw, it can choose to succeed instead.

Relentless Impaler

In the Domains of Dread, practitioners of foul magic perform a profane ritual that turns living creatures into fiendish killers. This ritual necessitates the use of a ceremonial stake, which is plunged into the heart of a living sacrifice. The hulking form of the relentless impaler then emerges from the sacrifice's pool of blood, spear in hand.

A relentless impaler is bound to the creature that wielded the ceremonial stake in the ritual that birthed it. As long as the original stake remains lodged in the heart of the ritual victim, the impaler can return over and over again to regenerate beside the victim's body, no matter how many times it is destroyed.

The impaler pursues its creator's agenda coldly and efficiently. It has no concern for its own self-preservation, knowing that, for itself at least, death isn't the end.
