A Hook (후크, hookeu, "hook") is an uncommon type of weapon in the Tower. They are generally used to pull, stab and crush. A basic example is "hooking" the opponent in order to restrict his/her movements.
- In fact, the Green April is a very unusual kind of hook, as it is a compression weapon that can be used for much more than just hooking enemies.
- Coincidentally, hooks are commonly used by Fishermen. This is most likely a subtle joke by SIU.
