Vegemite Necrosis

You spread a dollop of vegemite on the ground and utter a dark incantation. The vegemite begins to bubble and emit a foul odor. As you concentrate on the spell, 1d4 undead skeletons rise from the ground within 10 feet of you. The skeletons are under your control and obey your verbal commands, which you can issue as a bonus action on your turn. The skeletons remain for the duration of the spell or until they are destroyed. If the spell ends and any of the skeletons are still alive, they become hostile and attack the nearest creature.
