Swarm 2.0. The swarm can occupy another creature’s space and vice versa, and the swarm can move through any opening large enough for a Tiny aberation. The swarm can’t regain hit points or gain temporary hit points. A swarm takes half damage from attacks that use an attack roll and double damage from effects that require it to make a saving roll. Creatures that are not swarms are impaired while they remain in the swarm’s space or within 5 feet of it and have disadvantage on attack rolls and Constitution saving throws to maintain concentration. The area of the swarm is considered difficult terrain. Web Walker. The webbird ignores movement restrictions caused by webbing.
Swirling Bites. The swarm attacks all creatures that share a space with it and automatically does 7 ( 1d8+3 ) piercing damage, or 5 ( 1d4+3 ) piercing damage if the swarm has half of its hit points or fewer. The target must make a DC 14 Constitution saving throw, taking 9 (2d8) poison damage on a failed save, or half as much damage on a successful one. If the poison damage reduces the target to 0 hit points, the target is stable but poisoned for 1 hour, even after regaining hit points, and is paralysed while poisoned in this way. Web (Recharge 5-6). Ranged Weapon Attack: +5 to hit ( 1d20+5 ), range 30/60 ft., one creature. Hit: The target is restrained by webbing. As an action, the restrained target can make a DC 14 Strength check, bursting the webbing on a success. The webbing can also be attacked and destroyed (AC 10; hp 5; vulnerability to alcohol damage (one flask of wine will free a trapped creature after 1 round immunity to bludgeoning, poison, and psychic damage).
Egg Layer. When a creature is restrained by a web attack or incapacitated by poison, a swarm of these creatures will fly down and alight upon him or her. Their chest appendage is inserted into the immobile victim’s flesh, and the webbirds commence to deposit their eggs therein. These eggs will hatch after a long rest and the infected creature will feel unwell until that time gaining one level of exhaustion. After hatching, and thereafter the larva-like grubs will begin to devour the host, causing extreme pain and inflicting 1d2 levels of exhaustion per hour until the host dies and the webbird grubs can crawl out. Any disease curative, such as restoration, will kill the grubs.
