Right now there isn't much emphasis on element types. I've easily dealt with the 'hell/fire' level with pure Promethean magic and don't particularly care what damage types my weapon deals, just how big the number is. Would Dredmor benefit from a greater emphasis on the various damage types? It doesn't have to go as far as pure rock, paper, scissors but it might be nice to have some enemies have greater resistances (or even weaknesses?) to certain types.
