I like it. Nice consumable source from some champions and killing enemies all at once is just satisfying

imo this would be a lot more fitting as a trinket, as this is an intense thing to commit to. It could either make your life a nightmare, or trivialize the game. Being a trinket would balance it out, as if its too tough you can drop it, or if its really good you may need to consider passing up other trinkets for it.

Not worth picking up imo. The champion enemies now have tooons of health, good luck ever killing them first.

i picked it up, i killed a champion and my game immediately crashed

just saying that it crashes your game won't help, you need to tell me what did you do
Did it crash when starting a game? when killing an enemy? when you find an item?

crashes my game

Akad wtf your polish fox powers prevent us from translating things

I can confirm my theory. I copied everything from your lua file and pasted into a lua file in another mod, overwrite everything in it. Now I can translate it into Chinese and have no issues in game. Basically your lua file is different from others, some kind of format or decoding method are different, I don't really know. But your lua file can only contain 26 English letter in it, anything else will not work. You might want to check this out, because that means all your mods can't be translated to any other language with special letter. Including Spanish.

Maybe its because i edited lua file using notepad? i dont really know

I think the reason for Chinese won't work in the game is because your lua file. Like the spanish EID description, there're a lot of gibberish, like those strange symbol like "s髄o". I also have ancient revelation mod installed and the Spanish EID description in that mod seems normal in the lua file. The reason that cause Spanish letter to glitched is also the reason that make Chinese translation not working.

Sorry, i really don't know how to help you
Can you please send me this file? i will look into it

Oh, I also notice in your lua file, the spanish translation have something wrong in it, Los enemigos campeones no podr醤 aparecer de forma regular, haciendo que s髄o aparezca uno por sala#Derrotar a este enemigo campe髇 har?que todos los enemigos mueran#Los enemigos campeones tienen m醩 Salud

Hi. I'm trying to translate your mod into chinese and I have no problem with any other item mod before. However with this mod, if I changed the name "checked mate" in your lua file and the item/item pool file, to other English name like Checked M or something like that, the mod will work fine. But if I changed the name into Chinese, the mod will completely stop working, the item have no effect and the EID description won't show. I've already translate lots of item mod, non of them have this problem. Do you have any idea what cause it?
By the way, if you ask me what exactly I changed in your lua file, it's the name after "Isaac.GetItemIdByName", and the EID description line, I didn;t touch the name after (register mod) and other thing. And yes, the name in the item/itempool file also changed. I'm pretty sure I didn't change anything I shouldn't because I already successfully changing the item name into Checked M and everything work fine. It just not working with Chinese.

Yup, but i liked this idea so i made this

i think this one has a reason for being unused

I think just dealing heavy damage would be more balanced than outright killing all other enemies

It shouldnt? bosses should spawn normally with or without checked mate

thought this was OP until i found out it makes bosses champion too

well this is absolutely busted

Its actually confirmed mechanic by Kilburn, i just nerfed it a little bit

wait that's a really cool concept actually

I don't think theres a reason to do that :p

i think it would be cool if there was a 20% chance for the item to drop if you killed the rare,rainbow champion instead of a bunch of pickups

huh, very odd

I didnt find it, it were my friends who found it, and from what i heard there is only items sprites and funny book of gay penis sex

where did you find this website of sprites exactly?? and is there any for other things like monsters and bosses?

thanks! also, item's sprite actually comes from a website that has all antibirth items sprites: https://vinh.penisoft.com/isaac/

What an interesting item! With a nice sprite too! Good job!

thats not a problem ^^

Cool, sry for all the questions

no, it can only turn non-boss enemies into champions and only kills non-boss enemies and champion bosses can spawn normally

Nice! Does Checked Mate also afect champion bosses such as Red Mega Maw and Black Rag Man?

Probably will allow only one enemy to be champion

Cool, but what about the Champion seed, where all enemies become champions? Will Checked Mate still only allow one champion in a Champion seeded run?

not really, this item allows only one champion to spawn

Awsome item, but would it be too powerful in the Void chapter, where champions are more common there?
