Leveling up the Cathedral is getting harder.

I'm level 21 right now and it's super tough lol. The level 24 quest is impossible right now.

The level 24 hidden quest seems possible only if you give up on other things and gather a ton of speed items. If you give up on other things, you know what happens, right? You won't be able to handle the combat power or heroes. I'd love to hear some tips from those who cleared level 24. I gave up. I managed to get to level 23. Good luck!
