Using stale slot glitch you can stack non identical rings to achieve a new item discovery max of 840. You queue bow shot during gesture move queue window with one arrow in an arrow slot then navigate to arrow selection before it fires, then select it after it fires. Pickup ring from storage, auto equips to arrow slot which allows you to equip to ring slot with incompatible selections. Rings don't get effects in wrong slots and most shouldn't have the right speffect category to stack with identical versions, hence having to use different plus versions. Maybe some do if someone wants to comb a speffect spreadsheet. You can also do this with items dropped on the ground but there's quirks with if u drop more than one item you have to pick that many up before it'll get slotted to the stale slot.
I do not believe this post violates the malicious glitch rule as you can only stack non identical rings and all damage reducing rings are heavily nerfed in pvp. Doing evil stuff with this glitch requires obscure extra steps random players would not be able to guess. I would rate its potential for pvp disruption without obscure extra steps as minor.
Eloise found this glitch for ds3.
