Durability

Durability is a game-concept which limits the amount of usage an item or structure 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:

Tools

Tools lose durability whenever they are used for their specific actions and in the same way as weapons do when attacking something. 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).

	100	Chops down trees.
	400	Chops down trees.

	5	Fixes up degraded clothing.

Survival items

Survival items lose durability when used by the player or when triggered by mobs. Some of them can be used as weapons but will lose durability much faster.

	10 (4 when attacking)	Catches insects.
	9 (3 when attacking)	Captures fish and eels in ponds.
	20	Grows seeds.
	30	Grows seeds faster.

Weapons

Weapons 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 has a different number of uses.

Name	# of Uses	Special

	Unlimited	Spoils like food in 10 days.

	10	Damages mobs that walk over it.
	150	Spawns shadow tentacles on hit
	10	Puts nearby mobs to sleep.

Protection

Protective items include Armors and Walls. Armors are items worn by the player. 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). Walls can be placed to protect or limit access to an area from other mobs. They can be attacked and destroyed, but can be repaired and even upgraded to last longer. Stone Walls and Thulecite Walls are the only non-flammable walls.

	100%	500-800	Non-flammable.

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.

Amulets and staves

Staves lose durability when they are used while Amulets usually lose it over time while being worn. Chilled Amulets and Nightmare Amulets wear out in the same way as clothing, staves wear out as weapons or tools and Life Giving Amulet will lose durability itself by healing the character every 30 seconds if their health is not full.
