Amphibious. The tsathar can breathe air and water.

Keen Smell. The tsathar has advantage on Wisdom (Perception) checks that rely on smell.

Slimy. Tsathar continuously cover themselves with muck and slime. Creatures attempting to grapple a tsathar do so with disadvantage.

Standing Leap. The tsathar’s long jump is up to 20 feet and its high jump is up to 10 feet, with or without a running start.

Actions

Multiattack. The tsathar can make three melee attacks: two with its claws and one bite. It can use its flurry of blows or stunning strike ability in place of one of the claw attacks.

Bite. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 7 (1d6 + 4) piercing damage.

Claws. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) slashing damage, and the target must succeed on a DC 13 Constitution saving throw or become the living host to a tsathar egg, which over the course of the egg maturing, migrates to the chest cavity of the host. The host creature must make another DC 13 Constitution saving throw after 24 hours of the egg having been implanted. A failed saving throw results in the host becoming violently ill, followed by a deep comalike state that lasts 2d6 + 2 days. At the end of each day, the host can attempt another saving throw with a success indicating that its body has Tsathar managed to destroy the egg through normal immune response. At the end of the incubation period, the host awakes to excruciating pain as the young tsathar, freed from its egg, tears its way out of the host, who is reduced to 0 hit points in the process.

A DC 16 Wisdom (Medicine) check can be attempted to surgically extract an egg from the host. A lesser restoration spell will also cure the condition and purge the host of the egg.

Flurry of Blows (3/day). Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 14 (3d6 + 4) bludgeoning damage, and the target suffers one of the following effects of its choice:

• Prone. The target must succeed on a Dexterity saving throw (DC 14) or be knocked prone.
• Pushed. The target must make a Strength saving throw or be pushed up to 15 feet away from the tsathar.
• Agog. The target can’t take reactions until the end of the tsathar’s next turn.

Stunning Strike (3/day). Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) bludgeoning damage, and the target must succeed on a DC 14 Constitution saving throw or be stunned until the end of the tsathar’s next turn.

Reactions

Deflect Missiles. If the tsathar has one hand free, it can use its reaction in response to being hit with a ranged weapon attack. It reduces the damage by 14 (1d10 + 9). If it reduces the damage to 0, it can catch the missile if it is small enough for it to hold with one hand.
