Hounds of the Hunt

The pack can occupy another creature's space and vice versa, and the pack can move through any opening large enough for a Medium hound. The pack can't regain hit points from magical or nonmagical healing or gain temporary hit points. While summoned, the pack recovers all lost hit points whenever you finish a long rest.

The pack has advantage on Wisdom (Perception) checks that rely on hearing or smell and can track creatures across water.

The pack is immune to conditions that only apply to a single hound, such as poison from a weapon attack or a grapple. When determining whether the entire pack is affected by a condition, the hounds count as 4 Medium creatures that take up a 10-foot by 10-foot square. The pack has advantage on saving throws against spells and effects that target a single target, such as poison spray. The pack has disadvantage on saving throws against spells and effects that affect the entirety of the space it occupies, such as fireball.

The pack functions with a single purpose and has advantage on all melee attacks.

Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 10 (2d6 + 3) piercing damage. If the target is a creature, it must succeed on a DC 13 Strength saving throw or be knocked prone. If the pack's current hit points are less than half its hit point maximum, the target takes 6 (1d6 + 3) piercing damage instead and must succeed on a DC 11 Strength saving throw or be knocked prone.
