Durability

Durability is a game-concept which limits the amount of usage an item has. It generally applies to items which can be equipped, however there are some other items such as the Sewing Kit or Pan Flute which also have it. An item with durability can be identified by a percentage number in front of its inventory graphic. For example an Axe will have a 100% over its icon when first created, and this number will change as the Axe is used. Different items use durability in different ways:

Weapons
Weapons (and also Tools) use Durability to determine the number of times they can hit something before breaking. A Spear for example losses 0.66% of its durability each time it is used to attack something, allowing it to be used 150 times. Each weapon or tool has a different number of uses. The 3 most common Tools (Axe, Pickaxe, and Shovel) also have special versions with a much higher durability (Luxury Axe, Opulent Pickaxe, and Regal Shovel respectively).

Armor
Armor's Durability functions like extra Health for the character wearing it. Each type of Armor (Grass Suit, Log Suit, or Marble Suit) can absorb a certain amount of damage before breaking (225, 450, and 1050 respectively). When a character is hit, the armor takes a percentage of the total damage and the characters health takes the remainder. The number show on the armor's inventory icon is not actually the amount of damage it can still absorb, but the percentage of its own starting health (for example if a Grass Suit shows it has 50% durability left, it can still absorb 112 damage before breaking).

Clothing
The Durability of clothing indicates the amount of wear-and-tear the clothing has suffered. When equipped, a piece of clothing will gradually wear out, and its durability will decrease. Each clothing item wears at a different rate, so if a vest and a hat are equipped at the same time, one may wear out before the other. Additionally, clothing is the only item type which can have its durability restored, which is done by using the Sewing Kit.

Other items
There are several other items which have Durability but are not equipped. These items lose a set percentage of their durability each time they are used, resulting is a set number of uses. a Sewing Kit for example can be used 5 times, and thus loses 20% durability each time.
