This spell creates a pact which is enforced by celestial or fiendish forces. You and another willing creature commit to a mutual agreement, clearly declaring your parts of the agreement during the casting.
Heart of Dis
You magically replace your heart with one forged on the second layer of Hell.
A weapon formed from the essence of Hell appears in your hands. You must use two hands to wield the weapon. If you let go of the weapon, it disappears and the spell ends.
When you cast the spell, choose either a flame fork or ice spear. While the spell lasts, you can use an action to make a melee spell attack with the weapon against a creature within 10 feet of you. On a hit, you deal 5d8 damage of a type determined by the weapon’s form. On a critical hit, you inflict an additional effect.
Your body becomes catatonic as your soul enters the vessel used as a material component. While within this vessel, you’re aware of your surroundings as if you physically occupied the same space. The only action you can take is to project your soul within range, whether to return to your living body (and end the spell) or to possess a humanoid.
Area: Up to a 300-foot sphere
Wall of Flesh
A squirming wall of bodies, groping arms and tentacles, and moaning, biting mouths heaves itself up from the ground at a point you choose. The wall is 6 inches thick and is made up of a contiguous group of ten 10-foot square sections. The wall can have any shape you desire.
As part of the casting of this spell, you lay down in the coffin on a patch of bare earth and it buries itself.
