Krasue

Krasue is a hostile creature encountered in Abiotic Factor, functioning as a temperature-based variant of the Leyak. It is associated with freezing environments and is only able to appear when the player is already cold, such as in the Server Room in the Office Sector, Cold Storage in the Laboratories, the Residences area, immediately after leaving a freezing portal world like Voussoir, or during a Cold Snap. In practice, it is a stalking threat rather than a roaming one: it remains invisible to everyone except its current target, and it generally pursues only one player at a time.

Krasue moves only when it is not in direct line of sight or when it is far enough away from the player. Partial obstruction can still break its movement, including being slightly hidden behind windows. It cannot pass through walls, but it can move through player-placed deployables and open doors. Even so, it cannot kick doors, and placing a Deployable Object so that a door cannot fully open is enough to block it. It also emits short vocalizations resembling sighs or moans.

Its targeting behavior is persistent. Krasue usually focuses on a single player and continues to track that player for a long time, even if the target remains available and no one consumes any Greyeb. The target can change if the current target enters a portal world or is killed. Unlike the Leyak, its Gaze debuff is applied while the creature is looking at the player. After 10 seconds of uninterrupted line of sight, the player becomes Frosted and is frozen in place for 5 seconds.

Krasue can be repelled by the OX Tower or OX Lamp, which also causes it to drop Frozen Essence, or simply by staring at it with completely unobstructed line of sight. Doors, windows, and fences do not count as valid obstruction for this purpose. If stared at directly, it will demanifest and vanish after about 5 seconds. It will also attack if it gets close enough to the player.

It can be contained with Containment Unit: 91. The creature must be lured close and struck with an OX Lamp or OX Tower to force it inside the unit. Once contained, the unit must remain powered and regularly supplied with Vial of Milk to keep Krasue from escaping. The containment display uses two blue bars with multiple segments; one segment is consumed each day, and a fully fueled unit lasts one in-game week. Each Vial of Milk restores half of the containment bar, so two are needed to fully refill an empty unit. Frozen Essence is produced from the containment chute every morning at 6 AM.

In the GATE compendium, Krasue is cataloged as IS-0091-B, and it is noted for its resistance to a higher range of EM energies than the Leyak, requiring frequencies above 100 KeV to desubstantiate. It is also described as an extremophile theorized to originate in a frigid environment, with its presence significantly affecting nearby temperature gradients. Its resemblance to the Leyak and its Southeast Asian folkloric inspiration are reflected in the creature’s general presentation and naming.
