Amulet of Absorption

This amulet is found with 1d4 -1 charges on it, with a maximum of 10 charges. Charges are recharged by expending spell slots into the amulet at the start of a long rest, with any level slot recharging 1 charge. This trait cannot be used if you did not regain any spell slots during the rest. As a reaction, you may expend any number of charges on the amulet to gain temporary hit points equal to 1d4 + your spellcasting modifier for each charge expended, which lasts until the start of your next turn.

Cursed. This item cannot be removed once attuned to, except by spells such as Remove Curse or Greater Restoration. When this amulet is targeted by a spell that could remove or dispel the item, it attempts to defend itself by expending charges equal to the spell's level (up to 6). If it has enough charges, they are expended to cancel the effects of the spell. The wearer believes the necklace is a holy relic meant to keep them safe from harm, and will resist the removal of it to the best of their ability.

Notes: Attunement by a Wizard, Druid, Warlock, Bard or Sorcerer
