how about floor 300 always drop +3 gear from chests, floor 400+ has a 10 percent chance of +4 gear, floor 500+ has a 10 percent chance of +5 gear, this would see some nice lightweight bronze items and such being useful as well as the chance to get some real breath taking iron and steel pieces.
I’d also like to see flayers, ghostblades and liches having a 1 in 100 chance to drop a bronze weapon or shield as if it was from a chest (factoring questing skill and depth) and a 1 in 500 chance to drop an iron weapon or shield and a 1 in 1000 chance to drop a steel piece, these arent great odds but would make mob grinding a little more exciting as opposed to the completely pointless iron sword drops from ghostblades atm… tbh it would be better if ghostblades didnt even drop loot right now.
