TL;DR: We’re testing the loot system soon on PBE, details [here](http://na.leagueoflegends.com/en/site/2016-season-update/champion-mastery.html). We’ll be resetting PBE accounts to remove most unlocked content in order to get solid testing.
We’re going to be releasing the loot system to PBE in the very near future! We’re really excited to be able to show it to you, get some testing and hear your feedback.
Because this system is built around unlocking content, we’re going to be performing a partial inventory wipe of all PBE accounts in order to test the crafting system. We’ll be removing all owned champions, skins, ward skins and summoner icons -- except for exclusive content (such as ranked rewards icons, Triumphant Ryze skin, etc.). We won't be touching RP/IP amounts and you can re-purchase items in the store if you wish (but please try loot first before buying everything back up!)
If you find any bugs with the system, please use the bug reporting tool to report them [here](http://pbr.pbe.leagueoflegends.com/pbe/en_BE/bugReport/create). If you have problems with the tool, alternatively post in this thread. Please use this format - [link ](http://boards.pbe.leagueoflegends.com/en/c/bugs/CF5EEDC8FF5AC1A896F517E2C7AE4650C472807F-how-to-report-bugs-on-the-pbe)- for the format to use to report bugs.
Please leave feedback, and thanks for testing on PBE!
