Imbue
Imbuement is a term for when an Item requires the player to choose a specific ability of the hero they are playing. Typically the item will enhance only that ability, or provide a greater boost of Stats for that ability compared to the others.
Superior Cooldown as 
Shiv presents the option to Imbue an ability.Items refer to the selected ability as the Imbued Ability. Abilities not imbued by an item are referred to as Non-Imbued Abilities.
Ability imbuements are item-specific - imbuing two separate abilities using, for example, Superior Cooldown and 
Quicksilver Reload, will not grant both abilities the effect of both items. However, one ability can be imbued by multiple sources.
