Amulet of Necromancy

The Amulet grants a +1 bonus to Intelligence. They can also expend a charge to gain resistance to necrotic damage  and they can expend two slots to cast Animate Dead at 5the level. At midnight you regain 1d6+your int mod in charges. If you wish to gain an extra charge before midnight you must take 1d6 necrotic damage per charge and to regain four or more charges you have disadvantage on all attack rolls and saves against undead.

Notes: Resistance: Necrotic, When you attune to it you take 1d6-3 piecing damage as the spike pieces your chest. Only the attuned can take it off and they must make a DC:12 Con Save or they will still be attuned and take 1d6-3 piecing damage.
