If I wanted to change the % chance of a Splitting/Obliteration anvil destroying a book, would these two numbers be the two changes I would make? I believe these are the right values as it's 20% now but I just want to be sure so I don't mess something up lol. What would I put if I wanted say a 90% or 100% success rate with anvils enchanted with those enchants? What are different ways of going about changing something like this?

Also I do have a tiny background in C++ coding so I roughly know what is going on here. Just thought I'd mention that

Nevermind, figured it out
