Guild Feat - Afterlife (Orhzov Syndicate)

Strip the spirit from a dying creature, and beckon it to serve you. When a humanoid you can see within 60 feet dies, summon an Indentured Spirit (Guildmaster's Guide to Ravnica, chapter 6) at its location and impart the dying soul into it. The spirit serves you and follows your verbal commands until you lose control, free it, or perish. In combat, the spirit'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. The creature is under your control for 24 hours, after which it stops obeying any command you've given it. You can only command one spirit at a time and this requires concentration. If you lose concentration the spirit becomes hostile and may either attack you or try to pass on. Once control is lost, the spirit leaves after one minute regardless.
