Turtle's Quiet Travel

For the duration of the spell, each creature you choose makes all Dexterity (Stealth) checks with advantage.

This effect fools any nonmagical senses using sight, sound or smell. Creatures with Truesight or those relying on Tremorsense are not deceived. It also doesn't interfere with any detection spells that would find targets of this spell. This magic does not provide concealment for the purpose of Hide action and does not hide tracks.

Using a Higher-Level Spell Slot. You can target one additional creature for each spell slot level above 2.
