Ultimate Bravery
For the added challenge is Ultimate Bravery! Nothing is efficient! Everything is pain!
Ultimate Bravery is a kind of mode that let's you select a champion or group of champions, and get an output of random summoner spells, items, and which skills to max out first once a champion is chosen.
It's not something I would recommend for Ranked solo/duo queue. However, it can be a blast in Normals, but don't do it unless your whole team is down for it (ie, don't doom the lone guy that's been matched into your 4-Man Premade), but otherwise, it's a pretty fun mode to buckle down with for a few games, even if only in Co-op v AI. Hilarity and frustration both guaranteed. Give it a shot!
