Minion Skin Sets
Minion skins?? CharacterJunkie on Reddit came up with an incredible idea to help promote team themes and add flavor to the maps. Check out what he has to say, then click his imgur link because it's got some pretty sick minion concepts. Someone hand this man a beer...this is pure genius!
"League has so many matching skin sets for champions now (Pool Party, Pentakill, Arcade, etc.) that it gave me a cool idea for the minions. If your team has all five champions wearing matching skins, you would unlock minion skins that match your team. Only real problem is that not all the champion skin sets have every role filled. But I still thought it was a fun idea! Check back for more later. Minion skins for Mafia and Pool Party sets--> http://imgur.com/LfnhH8Z "
