I had a fun session with the game last night. I even managed to upgrade a couple of my characters to expert armour! I've now realized there are little icons next to the character levels that tell you whether or not you need to upgrade your character before you can upgrade that particular skill.My only problem now is trying to work out why the Jarl of Drangheim has sent me back to Angstram Keep with a new key when I've already cleaned that dungeon out for the Jarl of Stromford! Hopefully this is not a bug and there really is a door somewhere in the keep I can use the key on to access another level.
Anyhow, thanks once again ppl for your assistance. Going back to the game now...
