had a few ideas for other transformations:

jar of flies -> jar of wisps
sharp key/latch key -> mom's key
box/moving box -> box of friends
blood of the martyr -> the halo
the ladder -> the stairway (kinda busted but it'd be a pretty fringe scenario)
dunce cap -> mitre (kinda pushing it lol)
tiny planet -> sacred orb

Another item transformation:

E Coli -> Midas' Touch

I know it already turns Iron Bar into Midas' Touch, but really apart from the sprite they are completely different, while E Coli and Midas' Touch actually do the same thing.

Using Philosopher's stone in a room with rocks would transform a random amount of rocks into Fool's Gold rocks.

Any Fly -> Smart Fly

I suggest you make this a rune instead of an active item

An option to make it a 1 time use again, making it a rune would work too

You can make it a 1 time use by editing the MAX_USES at the top of the main.lua for the mod

Turn poop into golden poop upon use.
Apply midas touch effect on all enemies in the room for a brief moment.
Be able to duplicate pennies (not nickels or dimes or lucky pennies, if those are there just turn them into regular pennies without doubling) in the current room

IDK how difficult it'd be, but you should add Mod Config Menu support with one of the options being the max number of uses (with -1 being infinite like the challenge)

When i used Philosopher's stone with schoolbag, both my active items destroyed.

I can't seem to replicate this issue, do you have any more specific info? Everything I try as a test works fine

Maybe because i have turned on the option, that makes Philosopher's stone only one time use.
