Add rp with the monsters/combat, and add a custom enemy/npc/world creator
The custom enemy/npc/world creator sounds like a lot. I tend to pick fights with Oriana, Darian or Gareth if I want to RP combat. I always keep one or two NPCs at low relationship just to add conflict to dialogs and such.
in interested in turning fights with monsters into adult encounters or making them into followers instead of enemies.
