Dungeons with trust system

Hello! I have a question of the trust system and the EXP bonus. When you are on the "Trust HUD", there is one part that says: "Below 81 lvl: Y exp" (Y is the exp of the dungeon)

How does it work? I is split between me and the NPC, just for the NPC or just for the first time you finish it? I did the math and it is not exactly the one on the HUD.

Thanks!

I believe that the EXP shown is how much EXP the NPCs will earn upon completing the dungeon run. The amount they earn depends on their level.

Oh... you that makes sense.

Thanks!
