Drain Energy

You point towards a creature and attempt to extract their essence. Choose one ability: Strength, Dexterity, Constitution, Intelligence, Wisdom or Charisma. The target must then make a saving throw using that ability score.

The target immediately takes 2d6 necrotic damage on a failure, or half on a success. If the target failed the saving throw, for the duration of the spell the target must subtract 1d8 from all ability checks, attack rolls and saving throws made that use that ability. If the target hits with an attack made using the affected ability, the damage is reduced by 1d8 also, to a minimum of 1. At the end of the target's turns, it may make another saving throw using the affected ability. On a success, the spell ends early.
