Attribute Trick
Apply the ring or amulet then put the item on then take the ring off and the item won't turn red and you can still use it. Note this only works if the item you want to use gives you points to the attribute you need to boost.

Easy Money
Start a two-player game and load two characters or load one and start a new one. Now transfer all gold and any equipment to one character. Save that character and start a new game. When you load the character all you need to do is sell stuff and build a gold pile. Save again then repeat the process as needed.
