Your patron grants you a Demonic blade that acts as a conduit of your bond. The demonic blade can embody a weapon of your choice dealing Necrotic damage and gaining the vicious property. During a safe rest you can change what type of weapon it is.

1/Encounter: Use one use of Pillfered Power and put a curse on a creature you can see within 6 spaces. Attacks against this creature made from your Demonic Blade don't suffer the rushed condition and 1/round you can make an attack as a free action. When the creature dies you can use an action to put the curse on another creature within 6 spaces and your next spell cast does not cost a use of pilfered power

You gain +Int to your armour and are proficient with leather armour. When you defend against the enemy with curse of dread you gain Temp HP equal to Key

When you attack with the Demonic Blade you can deal damage equal to your eldritch blast (this counts as if it was used)

When you kill a creature with the Demonic Blade you gain Temp HP equal to LVL.

1/round: When you attack with your demonic sword you can have all your Shadow minions attack; but they all die at the end of the round.

1/ Rest When the creature afflicted by the Curse of Dread dies you can use 1 Action to make it explode dealing +Key d20 damage to creatures within 3 spaces.
