Afterbirth Custom Challenge Launcher
Make your own challenge runs!
Created 2 years ago
This is my custom challenge launcher for Afterbirth.
You can create your own challenge runs and share them with friends.

FEATURE LIST:

-Customize starting HP and consumables
-Choose starting trinket and card/pill/rune
-Choose starting items
-Enemy and boss health multiplicator
-Simple item pool editor
-Load/save challenge runs and share them through codes or files
-Random run generator

The item pool editor is a very simple tool which let's you change/combine item pools. For example you could make treasure rooms contain angel room items instead of treasure room items or you could make shops sell devil items AND shop items.

If you find any bugs or you have any suggestions feel free to post them and they might be fixed/included in the next version. Also I'm not a native english speaker, so if you find any GUI text which is bad english feel free to correct me.

INSTALL INSTRUCTIONS:

Just download the binary and start the .exe file. The tool should automatically detect your rebirth folder. If it doesn't it will prompt you to enter the root path of your Binding of Isaac - Rebirth installation.

Modify anything you want and hit the "Play" Button to start the run.

Using this tool may override following files. So it may collide with other mods which are using the same files:

players.xml
entities2.xml
itempools.xml
gfx/ui/minimap1.png
gfx/ui/minimap2.png

Why can't I set a spacebar item?
I tried giving myself Blank card, but that failed.
I was left with an empty space.
Active items like any of the books, razor blade, etc. don't appear. Everything else works fine but it's kind of a bummer I can't do stuff like razor blade / Isaac's heart
so i cant really start up the challenge so like ill go into the custom challenge of my own but then it wont show up when i start the game? anybody who knows how to fix this heres my discord https://discord.gg/Qy894yV

Your comment contains too many emoticon
mine doesn't work. Why does it keep crashing
How do you get the challenge off if you want to play normally again? And I don't know if reverting will mess up my save files or not.
fwoop don't you love how this can help you unlock characters easily?
Why can't I use this with afterbirth+?
I Just Use this To Unlock Characters and Items
Any chance that this will be able to change the starting stats anytime soon?
