Incubator

Incubator is an item class of consumable items which can be applied to a piece of equipment in a manner similar to currency. After a specified number of enemies of sufficient level are killed, the incubator will be removed from the item and drops an item from a pool of rewards specific to the type of incubator applied. Up to 10 incubators can actively incubate at once by default (one per each piece of equipment); after unlocking the trinket slot in a Heist blueprint, an additional incubator can be applied to a Thief's TrinketThief's TrinketCorrupted for a total of 11. Incubators can be applied to corrupted and mirrored equipment. Incubators applied to weapons or shields in your weapon swap slots will not accumulate kills when not actively equipped.

Incubators primarily drop from Legion encounters. Incubators drop with an item level which determines the item level of its reward, the selection of items which can drop, and the minimum level of monster required to accumulate kills.

Attempting to apply an incubator will cause items that are already incubating to display a small incubator symbol in the bottom right side of the item's icon.

When an incubator is at 75% or higher incubation progress, an icon and progress bar will be displayed on the right side of the screen.

The item level of the dropped item is described on the Incubator. So that players can use a high item level Incubator and then farm monster in lower area level, as long as it is the same or higher than the required level written in the Incubator. Since the required monster level is capped at 68, players can just farm T1 map to fulfill the kill count of any end game Incubator.
