Once you reach 6th level you may as a ritual raise an undead minion
as either a skeleton or a zombie from a humanoid corpse.
Undead creatures raised this way gain the following benefits:
-The creatures hit point maximum is increased by an amount equal to your warlock level.
-The creature adds your proficiency bonus to its damage rolls.
You may raise up to two minions this way instead of one at 7th level and up to three at 9th level.
On each of your turns, you may as a bonus action mentally command any minion made this way as long
as that minion is within 60 feet of you (if you control more than one minion, you can command any or all of them
at the same time issuing the same command to each one). You decide what action the creature will take and where it will move during its next turn
or you can issue a general command, such as to guard a doorway.
If you issue no commands the creature merely defends itself. Once given an order it will follow it to the best of its ability until the task is complete.
Minions created this way last until destroyed or dismissed but you may not have any more under your command than your level will allow. Any attempt to make more will cause
you to lose control of previously created undead.
Starting at 10th level you become immune to all diseases, poisons, and gain resistance against necrotic damage, and an advantage to save vs fear and charm effects. furthermore, you are immune to the poisoned condition.
Starting at 14th level you learn the rituals necessary to create unlife permanently. You can use this ability in two ways:
- You can use the Create Undead as in the spell, without components or using a spell slot. The created ghouls will stay under your control indefinitely. You can control undead in numbers equal to your warlock level.
