Demonic Ascension 1.5

You offer your entire being—body, mind, and soul—to Zahlkthar, the Demon of the Eternal Sands. In return, he grants you ultimate arcane knowledge and power… at an irreversible cost.

Upon casting this spell:

• You immediately drop to 0 hit points, and your maximum hit points become 1. This reduction is permanent and can only be reversed by sacrificing a sentient creature to Zahlkthar (at the DM’s discretion).

• You ascend to level 19, gaining all class features, invocations, and spell slots as if you had leveled naturally. However, you do not gain any additional hit points from this increase.

• If you die after casting this spell, you cannot be resurrected by conventional means. Your soul is bound eternally to Zahlkthar, and your body becomes a Living Grimoire, a sentient magical artifact containing your essence.

This spell can only be cast once per character lifetime, and only by warlocks who have made a pact with Zahlkthar.

Casting this spell is considered a dark ritual, and must be done willingly and knowingly.
