Fuse

is an ability in.

Overview
TotK: is an TotK: that allows TotK: to bond any NaN Items and most NaN Objects and NaN Weapons with his equipped TotK: or TotK:. Items from the Inventory can also be attached to NaN Arrows. Internally, the two parts of a fused weapon are distinguished as the "base" and the "attachment". Different attachments grant the base special NaN Fuse Properties, as well as other effects depending on what is used.

An TotK: that has been TotK: with a TotK: or TotK: can be removed in the Inventory to let the base equipment be TotK: with something else, but doing so will destroy the TotK: TotK: in the process. However, TotK:'s TotK: in TotK: can do so while preserving the TotK: TotK: so it can be re-TotK: with other equipment.

Weapons
Using Fuse on melee NaN Weapons has by far the most range of effects. Any Fused material will increase the attack power of the Weapon, and usually change its shape and thus its hitbox/reach. Base Weapons retain their NaN Weapon Traits and NaN Weapon Bonuss.

Fuse Properties
Almost every Object or Item fused to a Weapon grants it a new ability, known as a TotK:.

Durability
Using Fuse on a Weapon in effect increases its TotK:. The actual effect of this is that the base weapon gains access to a certain amount of "bonus" durability, which is 25 for most Weapons, and less for some others (see the below table). Any strike that lands with the Fused Weapon depletes this bonus durability, with the base weapon's durability not being depleted until either all bonus durability is used up or the attachment is removed or broken (however this bonus value is saved but not consumed during this state). Weapons attached to the end of another will use their own durability alongside the base weapon's, and break if it is depleted. However, if and only if the base weapon is Fused again, it can utilize any remaining "bonus" durability. Any attachment, regardless of its own durability (if it even has any), will break when the base weapon's base durability is depleted.

The sparkle at the top-right of the icon indicating if the weapon durability is at its fullest measures its total durability, thus any use of the weapon with or without the fuse will make the spark disappear.

As an example, if a TotK: (base) is Fused with a TotK: (attachment), the fusion will last for 15 hits– the durability of the Gloom Sword– without depleting any of the Fierce Deity Sword's base 35 durability, but depleting 15 of its 25 "bonus" durability. After the Gloom Sword breaks, the Fierce Deity Sword will use up its base durability until another fusion is made, which reallows the 10 remaining bonus durability to be used.

While a Weapon's base durability is used when it is an attachment, simply Fusing it restores its "bonus" durability. This means Fusing a Weapon to the end of another and detaching it at TotK:'s NaN Break-a-Part Shops effectively gives it more durability (usually 25) as long as the Weapon itself now has something else attached to it. However, Fusing also removes any TotK: modifier the attachment may have had, though these can be regained at random with NaN Rock Octoroks. Additionally, allowing a TotK: to swallow a Weapon will completely restore the base and "bonus" durability of both the base and the attachment. This can be used to repair Weapons that NaN Rock Octoroks normally refuse to when they are a base (namely, those received from crafting the NaN Champions' arms or from past games available from NaN Bargainer Statues or TotK:) and can be re-separated at the TotK: in TotK:.

Possibly due to an oversight, the "bonus" 25 fusion durability of the TotK: is never recharged alongside its base durability, and because the Master Sword cannot be dropped or Fused with anything this cannot be repaired with the above methods. This means the Master Sword will never again show the "sparkle" indicating full durability in the Inventory. The TotK: also cannot have anything Fused to it in the first place, though it technically has a bonus durability of 25 that cannot be utilized without glitches.

Shields
NaN Items and NaN Objects can also be fused to Link's NaN Shields. Shield Fusions do not increase durability or Shield Guard, with the exception of the long TotK: which increases Shield Guard by 1. This means Fusions with no special properties, such as most other Shields, do not do anything aside from modifying the Shield's hitbox and friction when TotK:. Depending on the TotK: being TotK: to the TotK:, TotK: may also be enhanced or outright disabled.

Arrows
NaN Arrows can be TotK: with NaN Materials to imbue them with more attack power or other special effects. This is done using the quick menu instead of actually utilizing the Fuse ability. As such, only Materials from the Inventory can be fused to Arrows, and not Objects from the overworld.

For example, unique to arrow fusion, NaN Keese Eyeballs that are TotK: with NaN Arrows can home in on NaN Enemies and NaN Creatures that would normally be too fast for TotK: to hit reliably, and NaN Arrows TotK: with icy NaN Materials such as NaN White Chuchu Jellies can freeze targets upon impact. Using a multi-shot TotK: will also apply the Fused material to all arrows while only consuming one.
