Yeah… Some additional loot or reward for doing dungeons might be in order, e. g.
- new armor and weapons,
- legendary chest weapons,
- Eldarium,
- treasure items,
- Recipe fragments,
- spell scrolls/potions,
- crystal golem parts (from bosses, not random chests…) or
- new consumables, e. g. a demon summoning wand similar to Zath spider orbs.
