Writhing Codex (Patreon)

Kill and zombify foes with breath of the master, do exactly what you think with corpse explosion, cast parasitic eruption to send someone to Cronenberg-ville, curse enemies with power word doom, become as resilient and unyielding as your animated minions via undead fortitude, disturb everybody at the party by conjuring a wall of flesh, protect your secrets with withering aura, travel in style by using wormway to hitch a ride in a purple worm, or go all-in and make the change into a wriggling mass of worms by casting the epic writhing transformation spell. Don't worry about the spellbook slithering a little bit—that's completely normal and nothing to worry about. Disturbingly designed by Ben Green, illustrated by Rachel Maduro.
