I created a tool that generates a random character for use in Ultimate Bravery matches. It gives you a random summoner, summoner spells, boots, boot enchant and five other items.
If you have any suggestions for improving this tool please comment below!
Edit: Some additional info.
1. You MUST buy the and finish the items in the order they are given, so boots first.
2. If you don't have a champion, just keep refreshing or use the Advanced generator.
3. You can easily copy/paste your build to show your teammates before hand.
4. Consumables are not at all brave.
Advanced Ultimate Bravery: I have created a tweak page where I will be adding various tweaks to the ultimate bravery character generator.
