Cover Up

While stealthing, sometimes the tiniest of bumps or the cracking of a twig can ruin the whole thing.

This spell allows the caster to muffle a sound, briefly cover an area with a still frame, or create a subtle distraction which makes a guard look the other direction at the very last moment. 

When you or another creature you see makes a Stealth check, as a reaction you can have them reroll the Stealth check and add your proficiency bonus. Clever use of this may let you use this spell for other checks too.
