The Glow Stick is an item added in the AberrationDLC for ARK: Survival Evolved. It provides artificial illumination and can either be held, or thrown.
Usage[]
To use the glow stick as a portable light source, wield it and use the alt attack button (Default: Rmb) to activate it. Holding right-click attaches it to yourself. Opening your inventory, using alt attack again, or wielding another item consumes the Glow Stick and extinguishes the light source.
To use it as a placeable light source, throw it with the attack button (Default: Lmb). It will stick to the first clippable object it touches and provides light for 12 minutes. Glow Sticks can stick to almost any surface, including players, wild and tamed animals, and resources like trees and rocks. In the latter case, if the resource is harvested the Glow Stick remains in place floating in the air until its timer expires.
Notes[]
Once placed into the world, Glow Sticks cannot be picked up again.
Glow Sticks can be dyed.
Adding an undyed Glow Stick to a stack of dyed Glowsticks will dye them without the need of new dye.
Dying the Glow Stick white will make it easier to see the lighted area compared to the base red color.
Glowsticks are very useful for tagging creatures such as the fast Procoptodon or the Invisible Shadowmanes and Rock Drakes greatly assisting in relocating them should they wander off. however in PVP this proves less effective due to being removed by opening the Inventory or Attacking. Spears may prove more effective in tagging players
