Pack Tactics. The clawfoot has advantage on an attack roll against a creature if at least one of the clawfoot's allies is within 5 feet of the creature and the ally isn't incapacitated.

Pounce. If the clawfoot moves at least 20 feet straight toward a creature and then hits it with a claw attack on the same turn, that target must succeed on a DC 12 Strength saving throw or be knocked prone. If the target is prone, the clawfoot can make one bite attack against it as a bonus action.

Attacker. The sidekick gains a +2 bonus to all attack rolls.

Second Wind.  The sidekick can use a bonus action on its turn to regain hit points equal to 1d10 + its level in this class. Once it uses this feature, it must finish a short or long rest before it can use it again.

Improved Critical.  The sidekick’s attack rolls score a critical hit on a roll of 19 or 20 on the d20.

Extra Attack.  The sidekick can attack twice, instead of once, whenever it takes the Attack action on its turn. The number of attacks increases to three when the sidekick reaches 15th level. If the sidekick has the Multiattack action, it can use Extra Attack or Multiattack on a turn, not both.

Battle Readiness. The sidekick has advantage on initiative rolls.

Multiattack. The clawfoot makes two attacks: one with its bite and one with its claws.

Bite. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) piercing damage.

Claws. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) slashing damage.
