Going Rogue (Akshan W)

A creature you touch has the Invisible condition and the target's Speed is doubled until the spell ends. The spell lasts for the duration as long as the target remains within 3 feet of a solid obstacle (such as walls, doors, or cliffs). The spell ends early immediately after the target makes an attack roll, deals damage, casts a spell, or moves more than 3 feet away from a solid obstacle.
