Item abilities have an associated ability level. By summing the ability level of each ability on a magic item, you can find that item's item level.

List of Ability LevelsEdit

Icy Burst: +2.

Ability Levels and Random LootEdit

When the game generates random loot, first the game decides an item type and an item level based on the level of the quest or combat area that the item was found in. From there, the game adds abilities until the sum of those abilities' levels is the target item level. Thus, by knowing an ability's item level, we can predict the earliest quests and lowest-level items that may carry that ability.
