Carrion Sense.

The swarm can pinpoint, by scent, the location of carrion, dead creatures, and Undead without the Incorporeal Movement trait within 60 feet of it.

Pilfering Swarm.

A creature in the swarm's space is surrounded by ravens pecking and pulling at its clothing, hair, fur, and belongings. If a creature in the swarm's space casts a spell with a material component, it must succeed on a DC 12 DEX save or the spell fails to cast, expending the action required to cast it but not the spell slot or daily use, as the ravens steal the component.

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 raven. The swarm can't regain HP or gain temporary HP.

Swarm Resilience.

The swarm is resistant to bludgeoning, piercing, and slashing damage, and it is immune to the charmed, frightened, grappled, paralyzed, petrified, prone, restrained, and stunned conditions.

Actions

Beaks.

Melee Weapon Attack: +4 to hit, reach 5 ft., one target in the swarm's space. Hit: 9 (2d8) piercing damage, or 4 (1d8) piercing damage if the swarm has half of its HP or fewer.
