Some items I would love to see in the game.
A key ring. A container that allows you to only put keys in it and if you have the key ring in your hand you can unlock a door without removing the key ring from the container.
The Halls of Justice has class specific merchants selling things for squires and paladins even one for High Priests but the merchant for priests only sells bandages. Adding some clerical robes would be nice and maybe a diaphanous blindfold.
(I know I will regret this later) Caltrops. Work a lot like marbles only they do a very low amount of damage when you walk through a room. To your mount if you ride through a room and no damage if you are flying or on a flying mount.
(I know this one was suggested before but I like it enough I am going to readd it) Little tags that can be added to items with a word on it. For example can add a tag to a potion that says slink and then you can 'get slink bag' and it will grab the potion. Allow you to add your own key words to an item.
Please feel free to respond to this thread with your own suggestions for items!
