1) Each named u kill in quests at reaper difficulty give Reaper xp equal to its level (this can be added after completion or during quest (yes can be farmed); if after completion, can be added and use multipliers (first time, etc.) or not). Why? Besides a mini bone for Reaper xp acquire, it promotes named hunting for long quests or even small quests, promotes the hunt for optionals, and will make u glad each time u find a named.

2) Multiply all reaper xp in epic quests by 2.
