Silvery Barbs

You magically distract the triggering creature and
turn its momentary uncertainty into
encouragement for another creature.
The triggering creature must reroll the d20
and use the lower roll.
You can then choose a different creature you can
see within range. The chosen creature has
advantage on the next attack roll, ability check,
or saving throw it makes within 1 minute.
A creature can be empowered by only
one use of this spell at a time.
