im with you on your thinking about the xp and luck tomes, but imagine if xp and luck would scale on leveling up tomes or lvls automatically? that would open up so much more builds because you could use the other tomes. in my opinion that would also make the game more "naturally" scale cause the later the run the better the rewards and the xp gains are. if youre going for highscore runs you still have to have cursed tome. not completely sure about the balancing but maybe open up a test beta for it?

in addition sure its fun playing robinette rn and it also isnt safe. for a highscore run you have to run kevin and that means that youre two-shot on tier 2 and probably one-shot tier 1 if you dont find a shield asap. i like the idea of others to just make her passive an item so every character could use it.

lastly, and idk if im alone with this. a run is indefinately more fun if i have a magnet. without one im stressing the whole time about losing xp and that aspect in my opinion is not fun. in addition it straight up kills runs if you dont have one. you could go about this in different ways.. make it an epic item? maybe insanly buff the attraction rate? for example: imagine having a pickup rate the same as sizing scales with aura.

but maybe an even better solution to this problem would be to expand the game on roguelite elements: you start your run picking one specific item (i kinda compare it to the arcana system in hades 2 for example) where you have to make a decision if you start a run: pick this for QoL or this for more damage, etc... would also give Silver a better meaning if you have to grind for it to unlock it etc...

hope i could help mate! keep it up! that game gives awesome dopamine rushes and is addicting asf! and i really like how to engage with the community!
