So, I always thought it was weird that we named things in game like our standard +1 to +3 items by number. All those numbers are generally an ooc number for the players though, so what if all those numbers were named differently instead?
My suggestion is as follows:
Rings of protection, amulets of natural armor, rings of resistance, scarabs of protection, and anything I Midas that follows the +1, +2, +3 progression follow this track
Lesser Ring of Protection (Ring of Protection +1)
Ring of Protection (Ring of Protection +2)
Greater Ring of Protection (Ring of Protection +3)
This would give is a better making convention by default, and make it easier to differentiate by in character terms as well.
That said! This is not super important, it's part of the nwn experience and we're all very used to it! It's more of a "wouldn't it be cool if" suggestion, and I have no idea how much of a headache it would be to change the name pig every item by that convention in the module.
But if you like it, neat! I'll have been a positive member of the community!
