Boon of Acheron's Blessing

Pick any creature the player can see.  That creature will be affected by ONE of the following spell conditions:

-Disadvantage on all Saving Throws until the creature's next turn

-Any attacks made on the creature have advantage until the creature’s next turn

Upon every other level-up (3, 5, 7, 9…) this ability gains another charge per short rest OR the ability to target an EXTRA creature.
