Create Greater Undead

You can cast this spell only at night. Choose 1 corpse of a Medium or Small humanoid within range that was of a CR rating 18 or level 18. The corpse becomes a undead of CR 17 or lower under your control. Example death knight.

The Undead you create with this spell take commands mentally as long as they are within 120ft of you or can hear you if a effect should block your mental link. The undead can perform complex or simple commands, able to carry out tasks and return independently. If attacked a undead will defend it's self and if left to it's own devices they will usually guard the area they were left, but they may start to act like actual undead of that kind if left without orders for to long. The average is 1d4 +1 months. If left to their own devices they will endeavor not to muddle in their creators plans willingly, some may even seek favor with their creator only to be released from undeath or hopefully receive a reward for their loyalty.

The creature is under your control for 1d4 +1 months. To maintain control of the creature for another 1d4 +1, you must cast this spell on the creature before the current period ends. This use of the spell reasserts your control over up to three creatures you have animated with this spell, rather than animating new ones.

At Higher Levels. When you cast this spell using a 9th-level spell slot, you can animate two undead. If one wishes to create a Draco lich, they must gather the ingredients needed and perform the ritual with at least 19 others spell casters. This ritual of creating a Draco Lich is risky and causes the loss of all casters spell slots for 14 days. A 1d100 is rolled, on a 1 the ritual failed, on a 2-50 it worked but the dragon becomes hostile due to its new undead hunger. On a 51-90 the Draco lich is friendly, on a 91-99 the Draco lich will help you allowing you to call in 1d5 +5 favors with it, it will not accept a request considered suicidal. On a 100 the Draco Lich is completely under your control.
