Attachments

**Attachments** are items that have an effect on the weapon if it is compatible.

There are two major types of attachments.

* The mechanical ones are obtained from the Weaponsmith and cost gold (unless he is rescued from a cage). The attachment given by the Weaponsmith is always compatible with the weapon equipped by the player when interacting with the Weaponsmith.
* Since Update 4.0.0, it is now possible to find exclusive attachments by fishing. However, the attachment found in this case is not guaranteed to match the current weapon.

The Redeem Machine is also able to give attachments if fed with the relevant vouchers. It is possible to obtain both types of attachments.

Most of the attachments are reusable ones, while some of them are single-use ones.

## Reusable Attachments

These attachments can be added to any weapon as long as it is compatible. If a weapon with this type of attachment is dropped on the ground, the attachment will also fall off and can be picked up again.

When a weapon is given this type of attachment, the weapon name will be followed by a star, in which the color is the same as rarity of the attachment. In the icon that shows what weapon the player has equipped they will be able to see a small image of the attachment below the weapon.

Some types of attachments may come with different rarities, such that their effects will also change. For example, a Grindstone of **Common** rarity provides +2 damage, while another of **Very Rare** rarity provides +4.

* Some weapons can only hold a certain type of attachments below a certain rarity. For example, a Hero Bow can hold a Grindstone of **Common** rarity, but not a **Very Rare** one, while it is still possible to hold **Fully Automatic Device** and so on.

All weapons cannot hold more than one attachment, while **Legendary** rarity and fishing-only weapons cannot have any. Followers do not use attachments and cannot equip them.

If an attachment can increase weapon damage for a charged weapon, the value will be doubled on full charge.

## Single Use Attachments

Since Update 2.5.0, it is possible to obtain a single-use attachment for applicable weapons. When used, the weapon is transformed into its corresponding variant and the attachment is destroyed.

## Trivia

* Attachments were added in Update 2.0.0.
* Formerly, merging weapons would cause attachments to be destroyed. Currently, they will fall instead.
	+ They may also fall when under the  condition, since weapons can get Reforged into ones that can't equip the current attachment.
* Before Update 2.3.0, if the player bought an attachment for a weapon that already had one, they could only get a different attachment.
	+ Also, if a weapon already had an attachment and found another of same type (like two Grindstones), it was impossible to change attachments directly, such that players needed to drop the old attachment first before installing the new one.
* Upon the addition of the single-use attachments in Update 2.5.0,  Rainbow Paint was also added to the game's assets, being the 24th attachment. It would supposedly transform Gatling Gun into Rainbow Gatling, but this attachment was never made obtainable.
* Before a certain update, under damage-modifying conditions, damage-amplifying attachments might cause weapon damage to change improperly. Currently, their values will be doubled or halved correctly.
* The 18th attachment is an unobtainable version of Poison Stone with unknown purposes.
* Even though Followers can't normally equip attachments, they're able to use attachments that spawn with their weapons if under the condition . However, they'll lose their current Attachment upon entering the next floor. This same condition allows Knights spawned from the Statue of the Knight to have attachments on their weapons.
