	clvl and ilvl control alvl of crafts by controlling the final ilvl that the craft receives. It follows this formula. ilvl = int(.5 * clvl) + int(.5 * ilvl). The int() means that you round down before plugging through the equation. Affixes control the required level of the craft. The formula is rlvl = rlvl(of highest affix) +10 +3x (#of ~~other~~ affixes). So if you have a craft with 3 affixes and the highest affix has a required level (rlvl) of 12 your required level for that craft is 12 + 10 + 3*2 = 28. Since character level controls affix level and the # of affixes that can spawn it also controls the rlvl of the craft.		clvl and ilvl control alvl of crafts by controlling the final ilvl that the craft receives.

	* '''Item Type:''' ~~The kind~~ of item~~; a cap~~, ~~a gem~~, ~~a short sword~~, a ~~ring, etc~~.		* '''Item Type:''' Each item is assigned an item type through the type column in armor.txt, weapons.txt, and misc.txt. All item types are defined in itemtypes.txt, and examples are Swords, Staves, Wands, Jewels and Misc. An item has one specified item type, although other item types may have an effect on it, eg. a Grim Wand is of the Wand type, which is part of the Rod item type group, which is part of the Blunt item type group, then Melee item type group, and finally the Weapon item type group. Because it's also part of the Blunt item type group a Grim Wand receives the +50% damage to undead bonus.

These are, in order of increasing scarcity: low quality > normal > superior > magic > rare > set > unique. Crafts are also considered an item quality.
	* '''Affixes''' The magical modifiers on an item; prefixes and suffixes. ~~(Not~~ all item properties are affixes. ~~For example: stuffmods~~, ~~pre—defined~~ properties ~~of crafted~~ items and ~~some special mods of set and unique items. E.g. "+60 to Mana" on magic ring is affix, "+20% crushing blow" isn't affix~~.		* '''Affixes''' The magical modifiers on a magic, rare or crafted item; prefixes and suffixes. These can be found in MagicPrefix.txt and MagicSuffix.txt. It should be noted that not all item properties are called affixes, only those found in MagicPrefix/Suffix.txt, the others are either simply called properties, or follow a different naming scheme such as staffmods and automods. Crafted items have both pre-defined properties that always appear and affixes.
	* '''Qlvl:''' Quality level. 1) A level of item type. ~~All these~~ levels are stored in the weapons.txt, armor.txt and misc.txt data files. 2) A level of set or unique item~~.

In v1.10 there are 29 weapon and 29 armor Treasure Classes ([[TC_1.10\|see those here]]), with additional TCs covering all the smaller, miscellaneous items such as runes, charms, gems, potions, etc. All TCs are recursive: this means that one treasure class may include another treasure class. E.c. Hell Baal drop all his items from "Baal (H)" treasure class, which consists of "Act 5 (H) Equip B", "Act 5 (H) Junk" and "Act 5 (H) Good" treasure classes.
