Nible's Challanges Idea

[Kacpert25]

Nimble's Challenges currently only rely on receiving emotes, which once you get all of them, makes Nimble a useless NPC. 
I think it would be useful to add some replayability to this mechanic.
For example, after obtaining both emotes from a given area, you could still complete challenges in subsequent runs, but the rewards would not be emotes, but a random item that can be purchased in the store (i.e. powers, resources, potion refills, etc.).
Of course, the rewards for completing the second challenge would be of higher quality than the rewards for the first challenge.
The challenges themselves could be random, i.e. apart from the two basic ones, there could also be some other general challenges or ones based on the mechanics of a given area or anomalies currently occurring in it.
Of course, then these quests would not be assigned to us directly from Nimble at the start of the run, but would be displayed for checking under Tab, since it is now possible.
