Embellish

Embellish a single memory of your target. Instead of having fought of a single wolf, make the creature believe they single handedly faced off against an entire pack, or that they defeated a massive dire wolf! Or, enhance the generosity they received from someone.

The target must make a Wisdom saving throw. On a successful save, the creature does not believe the embellishment and is aware you cast a spell on them.

The greater the alteration, the less likely it is your target will believe you. It is much easier to convince someone the Wolf they fought was a Dire Wolf than it is a Manticore. It is up to the DM to decide if the target receives advantage or any bonus to the saving throw.
