Spears are a consistent and reliable source of damage due to their abundance and ease of use. Smaller creatures can be taken out with one or two stabs, while a few more hits tend to ward off or kill even large predators. Throwing Spears at creatures up against a surface can pin them, rendering them immobile for a short period of time. The exact damage a Spear deals varies depending on the Slugcat, with Monk, SaintIn Expedition dealing 0.6-0.9, Survivor, Rivulet dealing 1, and Hunter, Artificer, Spearmaster dealing 1.25, and Gourmand dealing 3 and 0.3 damage while exhausted.
Spears also have a few limitations: they can't be swallowed, only one can be held at a time (though Hunter can carry two by putting one on their back, and Spearmaster can dual wield them along with other Slugcats with the relevant perk in Expedition), and Spears that hit a target can only be picked up again after a short cooldown, which can be circumvented by using more than one Spear.
Spears also have a variety of other uses besides combat. They can be thrown and embedded into most solid surfaces, functioning as short climbable poles. This allows the player to reach otherwise inaccessible areas without the help of other creatures or items. Lodging Spears into floors or ceilings via a down-throw or up-throw can also be useful in a few locations. It's also possible to lodge Spears into ceilings by performing a slide-throw at a slope, although this is very niche.
Spears can also be helpful while gathering resources. Thrown spears can skewer Batflies, open Popcorn Plants, detach Blue Fruit from vines or knock a Vulture's Mask from its face by hitting the back of its head.
Spears can be given to Scavengers in exchange for other low value items and a slight reputation increase. The combined trading value of a Spear and Overseer Eye adds up to 10, which is enough to safely cross a Scavenger Toll, and can make for a good, reusable alternative if no Pearls are available.
Spears can collide and deflect each other mid-air.
The cooldown before a Spear can be picked up again lasts exactly 15 frames (0.375 seconds).
Spears embedded into surfaces fall out after 3-6 cycles. They can be found near the spot where they were embedded, guaranteeing a Spear spawn in that area.
When playing as Hunter, it's possible to wield a Spear in both hands at once by performing a slide-spin over a Spear on the ground while already holding one.
Rubbish spawning in at the start of a cycle has a 20% (1/5) chance of being a Spear instead. As Hunter, the base chance is raised to the power of 0.85, resulting in a chance of approximately 25% (1/4). Additionally, spots that require wall-spearing to progress often have multiple fixed Spear spawns.
Up-throws have lower damage than horizontal throws and do not benefit from damage-boosting abilities of specific Slugcats.
This does not affect Slugcats whose throwing ability is already lower, such as Monk or starving Slugcats. Combined with the fact their damage is random, this means that their up-throws can sometimes deal more damage than those of other Slugcats.
