Disguise Memory

You choose three creatures with the spells range and must make a Wisdom saving throw; If a target fails, you alter the memories of that target.

If a creature were to cast Detect Thoughts on a target, it would see the targets true memories. Once the target hears something that contradicts the memory it can make a Intelligence saving throw to dispel the effect.

This effect lasts until you dispel it, it succeeds on it's Intelligence saving throw or someone casts Dispel Magic on the target.

This spell doesn't affect constructs, undead and creatures who are immune to being charmed.

If you cast this spell as a ritual, the spells range is doubled and can effect twice the amount of creatures.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, you can affect one additional creature for each slot level above 3rd. The creatures must be within 30 feet of each other when you target them.
