Displacement (Recharges after the Lich Casts an Illusion Spell of 1st Level or Higher). As a bonus action, the lich projects an illusion that makes the lich appear to be standing in a place a few inches from its actual location, causing any creature to have disadvantage on attack rolls against it. The effect ends if the lich takes damage, it is incapacitated, or its speed becomes 0.

Magical Illusion. As a bonus action, the lich can mask its shriveled flesh and appear to be a living human. This magical illusion lasts until it ends it as a bonus action or until it uses its Frightening Gaze legendary action. The effect also ends if Vthe lich drops to 30 hit points or fewer, or if dispel magic is cast on it.

Illusory Self (Recharges after a Short or Long Rest). When a creature makes an attack roll against the lich, it can use its reaction to interpose an illusory duplicate between the attacker and itself. The attack automatically misses the lich, then the illusion dissipates.
