I mean a really small change.
For example: Have Fist Weapons in Dark Souls 1 do double damage. That’s a small change, which could be implemented by changing a couple of values. A big change would be: Adding the sixth Archstone in Demon’s Souls with the Northern Limit area. That’s a big change, and it would take a team a couple of weeks to implement, but that’s not what this post is about. I’m talking about really small changes that could be implemented in a lazy afternoon or two.


Such an item would have been extremely helpful during my RL1 runs. I also wouldn’t say no to a Boss-Rematch feature like in Lies of P in Fromsoft games.
Also as an aside: Challenge runners and speedrunners use ERTool in Elden Ring for creating the effects you described. It’s easier to use than Cheat Engine and has many more easily enable functions like: Repeat enemy actions, infinite stamina or HP or consumables, Rune Arc always on, RTSR set-up…
There are also other similar tools for other Souls games. I don’t know which one is best for which game, sorry. Look up [game] practice tool.
Full disclosure: I only saw other people use these tools. I didn’t use them myself, since I’m currently on console.
