MMOItems features an item generator which you can use to lower the amount of config files needed to create same versions of the same item. The idea is to have a set base item which is called an item generation template, and a set of generation modifiers, which add extra stats to the base item. The rarer the item is, the more modifiers it has, and the stronger the stats are.
When being generated, items all have an item level which directly determines how strong the item stats are and a modifier capacity which determines how many modifiers the item can have.
MMOItems item generator hooks onto the MMOItems tier system. The higher the item tier, the more modifiers the item has. In other words, the item tier determines the item modifier capacity.
Example
These items have the same generation template, which is an item called Long Sword. However, the right one has a Sharp modifier which gives him +3 Atk Damage while the left one has no modifier.
These two items have the same attack speed because it was chosen not to scale with the item level. However the attack damage does scale with the item level: although the first item has got a higher level, the second item has a Sharp modifier and therefore has more attack damage.
The Sharp modifier gives the second item a Sharp prefix as well as an extra line of lore.
Second Example
The item at the right has a much higher item level and therefore his attack damage is much higher. It also has two modifiers: Sharp and Fiery. Sharp still gives the item +3 Atk Damage but it's slightly useless given its level. Fiery gives the item a nice red name prefix and a on-hit burn ability.
The second item has the Rare item tier, therefore has much more modifier capacity than the non-tiered sword, which explains why it received two modifiers. Non tiered items also have a modifier capacity, but it is less important.
You can only see the Fiery prefix because this modifier prefix has a higher priority (although you can configure modifier so all prefixes show at the same time for extra fun!).
Item with multiple modifiers
The default item is a bow with some attack damage and crit chance. The first Heavy modifier makes it two handed, adds a few attack points and some critical strike power. The second modifier which has a suffix adds an on-hit ability with custom damage which scales on the item level.
