Jungle clear category now exists, where you have to full clear your side of the jungle. You won't see it with other categories, but on he sidebar there is now "Level Leaderboard" where you can find the category subdivided for all champions. Have fun practicing your first clears!
is currently the discord server which you can join from the sidebar.
If you are interested in running any category and want some tips, wonder how something is possible or done (like the practice tool runs) the best way to get an answer is to just ask on discord, many people there will be happy to help you.
I realize that having guides and tutorials which everyone can access directly from the site is better, but we don't have them, so for the time being join our discord if you're interested in running the game.
