Hooks are 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. Hooks usually don't increase in length, but some do.
The Arms Inventory is one of the three major kinds of inventories in the Tower. It is used for storing weapons.Arms Inventory is the basic armament used by all Fishermen, but it is not restricted from use by other Positions. Arm Inventories are customised for the storage of each user's weapons. They are not limited to what weapon they can hold, as they have shown to also hold bombs. Capable of turning invisible. An example of an Arms Inventory is
An Observer is a modified Ball used by Scouts. They collect visual data and pass the information on to both the Scout himself and also to allied Light Bearers, who in turn analyze these data and coordinate their own team accordingly. They are able to illuminate the darkness and is also able to project a hologram. They are also capable of helping Light Bearers using Flow techniques. Capable of turning invisible, but will not work when invisible. An example of an observer is
Needles are one of the most common weapons in the tower, but also one of the best. They are thin spikes, generally used to pierce and stab. One reason the Needle is the most basic weapon in the Tower is that piercing and thrusting attacks receive less Shinsoo resistance, and are technically more aerodynamic(able to move better in Shinsoo). A sword will have to break through more Shinsoo due to having a greater surface area. They are usually used by Fisherman and Scouts.
A Pipe is a Arms Inventory for Spears only. It is used by the Spear Bearers to carry multiple spears at a time. Pipes are known for being very heavy. Capable of turning invisible
A Reel is a spool (a cylinder) used for winding a long and flexible line which has been fed through the Reel and it can, in turn, allow the Fisherman to adjust the "reach" of the line. A Reel can be manipulated with Shinsoo, to rewind or unwind the Reel and to control the length and direction of the line. The line of a Reel is used to tie and throw weapons such as Needles and Hooks. The line is probably considered as part of the Reel, so a Reel is the main weapon used by Fishermen.
A sword is a weapon consisting typically of a long, straight or slightly curved, pointed blade having one or two cutting edges and set into a hilt.
A Wand is an item with the ability to create and collect an amount of Shinsoo. The ability to control Shinsoo is very rare, and most Regulars and Rankers use special items when they wish to manipulate larger amounts of Shinsoo. Wands can vary in shapes and sizes, either being an actual wand or long staff or a ring or earring.
A spear is the weapon most commonly used by Spear Bearers. They are generally two kind of spears, the ones used for stabbing and the ones used for long range throwing. Some of them are of such quality that they can be thrown vast distances. Spear bearers use a Pipe to carry their spears.
Pockets are devices that provide a variety of functions that aid Regulars and Rankers in the Tower. It is seen as a "symbol" of strength for the Regulars. They are generally round in size and are able to go invisible. Enables one to meet with a Guardian to attempt to make a contract.

An Ignition Weapon is a powerful type of weapon used in the Tower. An Ignition weapon is said to be a weapon with a soul. However, instead of thinking that all ignition weapons have souls, it's more accurate to say that they're created using a special kind of Shinsoo. When activated ( by either saying "ignite" or "start engine") it releases vast amounts of power, enhancing its speed, damage, etc. A branch form of Ignition weapons are Compression Weapons.
- Compression Weapons: A variant of the Ignition Weapon. Compression weapons often resemble normal weapons, yet actually contain far more mass than their volume would normally allow for. Apparently these weapons can be "decompressed" to their full size, although this has not yet happened in the series.
Ignition Weapons are rare in the beginning Floors of the Tower, but become more common as you go up.
