Ashir's Vivid Strike

The next time you hit a creature with a weapon attack before this spell ends, the weapon gleams with fey magic as you strike. The attack deals an extra 1d6 force damage to the target and must succeed on a Wisdom saving throw or be outlined in a color of your choosing, becoming visible if it is invisible, and can’t become invisible until the spell ends.  . Additionally, the next attack roll made against the target has advantage or the next saving throw it makes has disadvantage before the end of your concentration, whichever happens first ends the effect of this spell on the creature.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the extra damage increases by 1d6 for each slot level above 2nd.
