Amulet of Sin (Wrath)

Once per long rest, you can use a bonus action to enter a maddening anger for 1 minute. While in this state of anger, you are immune to the Charmed and Frightened conditions and are resistant to Psychic damage. If you are already Charmed or Frightened when using this bonus action the condition ends.

The amulet has 3 charges and regains its expended charges daily at dawn. You can expend 1 charge to get one of the following effects:

• As a bonus action, you can spend one charge to choose a creature you can see within range and mark it as the target of your anger. Until your Maddening Anger ends, you deal an extra 1d6 damage to the target whenever you hit it with a weapon attack, and you have advantage on attack rolls against your target if you are grappling it. If the target drops to 0 hit points before your Maddening Anger ends, you can't move or take actions until after your next turn, as a wave of lethargy sweeps over you.
• As a bonus action whenever you make an Intimidation check you can spend one charge to roll an additional d20. You must choose to do so before the roll, and you can do so only once per turn.

Notes: Can only attuned one Amulet of Sin at the same time. For a given player, any Amulet of Sin will always have the same effect when attuned.
