That token could be handed in to an NPC in abyss that would spawn 1 of the bosses left on your task list.
no...this would make t5 trivial because its the last 5 or 6 bosses that make it hard...
Perhaps that NPC appears after a full clear, or some other trigger. I would put the NPC in the arena area.
A npc that spawns after a full clear with some sort of chest is not a bad idea....maybe it drops an item that is lore and you can turn in for berries?
I think this might allow the task completion to be cleared up, and not trivalize t5. 1 boss you need per day does not seem OP.
Again this would remove the challenge from t5.. you could do the hardest part over several days with 30 min missions....lame..
Also please reconsider the ability to sell back prisms even at 1 berry per I think people would appreciate it.
Yea people would like this but i would not hold your breath...
