Gatekeeper

The Gatekeeper is a formidable undead guardian found exclusively in The Infinite chapter. With 10 HP, 20 Shield, and 1 Brace, its effective durability far exceeds its raw health pool. It targets the cat with the lowest max health and uses a Soul Drain ability that instantly kills its target while permanently reducing their Constitution by 2. This makes the Gatekeeper one of the most dangerous threshold enemies in the game, as its damage is not just lethal but permanently debilitating.

Beyond its instant-kill attack, the Gatekeeper can summon skeletal minions including Skeleton Cats, Tall Skeleton Cats, and Bone Worms, flooding the battlefield with additional undead threats. It also performs long-range jumps similar to the Abandoned Ones, allowing it to close distance unexpectedly. Its undead classification means standard revival mechanics do not apply to it, and Holy Shield cannot protect against its Soul Drain.

The recommended strategy is to maintain distance and use hit-and-run tactics. Since the Gatekeeper has only 10 HP behind its 20 Shield, abilities that bypass Shield are extremely effective at bringing it down quickly. Champion Gatekeepers have 20 HP, 40 Shield, and 3 movement. The enemy is possibly inspired by Saint Peter as Heaven's gatekeeper, and the cattle skulls in its design may reference the Chayyoth from biblical descriptions.
