Illusory Form. The Phantom Beholder can cast *Disguise Self* at will to appear as a true beholder.

Gas Cloud. When it drops to 0 hit points, it releases a cloud of spores in a 15-foot-radius sphere. Each creature in that area must succeed on a DC 14 Constitution saving throw or be poisoned for 1 minute. A poisoned creature can repeat the saving throw at the end of each of its turns.

Actions

Multiattack. The Phantom Beholder makes two Tendril attacks.

Tendril. Melee weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 10 (2d6+3) necrotic damage. If the target is a creature, it must succeed on a DC 14 Constitution saving throw or its hit point maximum is reduced by an amount equal to the necrotic damage taken. This reduction lasts until the target finishes a long rest.

Spore Burst (Recharge 5-6). The Phantom Beholder releases a burst of spores in a 30-foot cone. Each creature in that area must make a DC 14 Constitution saving throw, taking 17 (5d6) poison damage on a failed save, or half as much on a successful one.

Lore & Description

Appearance

The Phantom Beholder resembles a classic beholder, its spherical shape covered with a mottled green and brown texture that mimics the appearance of rotting flesh and moss. At its center are bulbous core-like structures that pulsate and emit a faint glow of eerie bioluminescence. Instead of eyestalks, it features tendrils that extend outward, swaying gently as if in a breeze.

Behavior & Origins

Found in deep forests and dank caverns, the Phantom Beholder lures adventurers with its appearance, which they mistake for a true beholder. Inquisitive creatures drawn near will unknowingly become subjects of its parasitic nature, as the Phantom Beholder releases intoxicating spores to weaken their resolve and drain their vitality.
