I use this to remind me of what challenges give what reward, mainly the repeatable challenges. I also put a little note on the "value" of the challenge as a repeat. A few near the end are the first time reward as I have not completed them yet to see the repeat reward. Some of the TAKES info is cryptic sorry, it is only a cheat sheet not the skyblock bible. At least now I am not spamming  /c over and over. GOOD LUCK!
