Chardun’s Army

You must cast this ritual so that it ends during nighttime. Corpses and bones of Small and Medium humanoids within a 150-foot radius of you animate as up to 40 undead under your control, assuming enough remains are present. Bones become skeletons and corpses become zombies. Alternatively, you can assert control over uncontrolled skeletons or zombies in  he area, but the maximum number of undead created or controlled remains limited to 40. You can use a bonus action to mentally command any creature created or controlled with this ritual, as long as the creature is within 150 feet of you. To command multiple creatures at one time, you must issue them all the same command. When the duration ends, 75 percent of the undead created with this ritual are destroyed and turn to ash. The remaining undead become uncontrolled. However, if uncontrolled undead have a clear task remaining when they become uncontrolled, they tend to keep performing that task.
