Wraith's Army of Death

Releasing a massive wave of necromantic energy you attempt to raise an army of undead soldiers to do your bidding. Targeting all corpses or remains within 120 feet of you and not behind total cover, you raise 2d10 * your spellcasting modifier HP worth of 3 or more medium or small undead, each taking the form of an undead with an Intelligence score of 10 or lower that you choose. The undead servants are friendly to you and any creatures you designate, following all orders received from you without question. Your undead army acts on your initiative, taking their actions right after yours. As a bonus action on your turn, you can mentally command up to 10 of the undead within 1 miles of you to preform an action, which they do to the best of their abilities until given another. If not given a order, the undead defend themselves against all hostile creatures. 

This spell can only be cast once per week, with all previous undead raised by this spell being destroyed or included in the new casting.
