Dark Reaping

Increase your Strength or Charisma by 1, to a maximum of 20.

Additionally, when a creature within 30 feet of you is reduced to 0 hit points and dies, you can feed upon the power of their death to gain your choice of one of the following benefits:

• Temporary hit points equal to your total character level + your Constitution modifier, which last for up to one minute.

• The first attack you hit with on your next turn deals additional necrotic damage equal to your total character level + your choice of either your Strength or Charisma modifier.

• Advantage on all saving throws until the start of your next turn. Once you use this ability, you must finish a short or long rest before you can use it again.
