Guild Feat - Undergrowth (Golgari Swarm)

Choose a corpse of a Medium or Small humanoid that you can touch. You place seeds or mushroom spores into the corpse. Plants or mushrooms grow and wrap themselves around the remains, and animate it to do your bidding. The target becomes a Shambling Shell (zombie), is considered both undead and a plant, and remains animate until the next long rest, after which time it collapses and dies, becoming a pure plant. In combat, the Shambling Shell's turn comes immediately after yours. It obeys your mental commands, and the only action it can take is the Attack action, making one melee attack.
