Animated Masque and Wand

Antimagic Susceptibility. The masque and wand are incapacitated while in the area of an antimagic field. If targeted by dispel magic, the masque and wand must succeed on a Constitution saving throw against the caster's spell save DC or fall unconscious for 1 minute.

False Appearance. While the masque and wand remain motionless and aren't flying, they are indistinguishable from inanimate items.

Eldritch Treasure. After the magic animating these items dissipates,  they can be used against their creators. The Wand of Eldritch Blast (using Charisma modifier) has 3 charges that reset at each dawn and the Disturbing Visage Masque can be used once per combat encounter.

Multiattack. The animated masque and wand makes two Eldritch Blast attacks.

Eldritch Blast. Ranged Spell Attack: +3 to hit, range 120 ft., one target. Hit: 7 (1d10+2) force damage.

Disturbing Visage (Recharge 5-6). When damaged by an enemy, the masque can magically haunt it using its reaction and forcing disadvantage on its next attack.
