Mage Eater Scythe

Alter: This dark metal scythe bears a fiendish grin along its blade. You gain a +2 bonus to attack and damage rolls made with this weapon. Whiel holding the scythe, you have advantage on saving throws against spells and other magical effects. When you hit a creaturewith an attack using this scythe, you can spend 2 or more hit dice (maximum of 4) to deal extra necrotic damage. The extra damage is 1d6 for each hit die spent in this way. If the creature has cast a spell since the end of your last turn, the extra damage becomes d10s instead of d6s, and that creature loses a total of spell slot levels equal to the number of hit dice you spend. Starting with the highest spell slot level that the creature has (up to 4th), subtract each slot level from the total, if possible, before moving on to the next remaining spell slot level.

Alternatively, while holding the scythe, you can use an action to spend 5 hit dice to create a magical barrier around yourself. Whiel the barrier exists, you can't be affected or detected by spells of 5th level or lower unless you choose to be, and friendly creatures within 10 feet of you have advantage on saving throws against spells and other magical effects. The barrier remains as long as you concentrate on it (as if concentrating on a spell), up to 1 minute, or until you drop or stow the scythe.
