Carrying objects/monsters/people (cantrip):
dark tendrils exit your body and pick up objects or creatures. any object under 250 pounds can be lifted and manipulated at will (5 objects max). when you try to grab a person or monster they must make a strength save or they are picked up by the tendrils, on their turn they must make a strength save to escape the tendrils.
Weapons (1st level):
you can create any weapons that you can think of. the weapons you create deal necrotic damage, the weapons you create can be disarmed, but disappear when they touch the floor (the mist weapons can be manipulated with the tendrils without using an object slot.)
Armour (cantrip):
you use the tendrils to cover yourself in any area you would like, you can make the armour light, medium or heavy armour. the armour is resistant to necrotic damage.
Clone creation (5th level):
you can create clones of yourself (max is 5.) if your armour is covering your entire body, including your face. your clones can not attack they can pick up objects up to 250 pounds and interfere with fights with said objects or distractions. it takes a whole turn to command all of them to do something in succession.
Ultimate move (9th level):
you can make an ultimate move with any means (the move can be stronger if you touch a solid object eg. floor wall ceiling) , which it takes 2 rounds to activate (it has to have a cool name though.)
