Swarm of Tritails (5e Creature)
From D&D Wiki
Swarm of Tritails
Large swarm of Tiny beasts, unaligned
Skills Acrobatics +7, Perception +5
Evasion. When the Swarm is subjected to an effect that allows it to make a Dexterity saving throw to take only half damage, it instead takes no damage if it succeeds on the saving throw, and only half damage if it fails.
Lifesense. The swarm can sense the life-force of living creatures and plants. When viewing constructs, undead, and necromancy spell effects, the swarm treats them as if they are in dim light.
Swarm. The swarm can occupy another creature's space and vice versa, and the swarm can move through any opening large enough for a Tiny beast. The swarm can't regain hit points or gain temporary hit points.
Multiattack. The swarm uses its Force Dart four times, or two times if the swarm has half of its hit points or fewer.
Force Dart. The swarm coalesces energy into a dart-like form and hurls it at a creature it can see within 120 feet of it. The dart deals 3 (1d4 + 1) force damage to the target, striking unerringly.
The tritail (\ ˈtrī-tāl \) is a humming-bird size bird. It appears as a tiny yellow swallow with a tri-fork tail. When they swarm, it is to protect their territory against a perceived threat.
