It would be interesting to have enemies who actually crouch sometimes when being attacked or dissappear only to reappear behind you. Or have some enemies flee a short distance to either drink potions,eat food or simply run away.
2.armour immunity As i feel it is my duty to make this game as hard as possible i suggest that some monsters are immune to the skills that some armour gives you. E.g orcs are immune to skills by rings. Imps are immune to skills by helmets Lizards are immune to skills by boots.
I.e to say if any of these armour has say"identify creature" and you are wearing this armour when fighting the above then the skill wouldnt work.
Demons-i feel that there should be demons around level 49(only 20 of them) who each have low attack/defence but high hitpoints say like 1200. They would be found in a sort of lava pit and would have high resistances to spirit/fire. The odd good weapon and money would be the main drop.
Dragons- for me they would be deep in the cave,say they would be only 8 of them in the game and they would guard huge amounts of treasure gems. They would have a high attack/defence but only around 900 hitpoints. High resistance to poison and lighting
