A mod to The Binding of Isaac, making that first Treasure Room contains an item of at least 3 Quality.
Warning This mod only works with AB+ DLC and does not work Repentance.
Please subscribe to this mod on Steam Workshop here.
There are mods like that, but they do not work with AB+. That's because Quality attribute was added in Repentance and can't be easily accessed in Lua.
So how does it work? Easy, just listed every item with 3+ Quality in Repentance ranking. (Also, I know that most of these items aren't in Treasure Room's item pool, so I listed them all. Of course only those actually present in this pool will be rolled)
There is only one known, Accessing Game():GetRoom():GetType() sometimes throw C stack overflow. I do not know how to do it the other way. If you tried something, and it worked, or have another improvements, please open a pull request.
