ARAM has 65 champions that are free-to-play by default, mostly to avoid people making ARAM-only accounts full of poke champions. If a champion from the list also happens to be on the weekly rotation, there won’t be any other champion to ‘compensate’ for it. As for the list, it is as follows: Aatrox Ahri Akali Amumu Annie Ashe Brand Braum Caitlyn Cho’Gath Darius Draven Ekko Ezreal Fiora Fizz Garen Graves Irelia Janna Jarvan IV Jax Jhin Jinx Karma Karthus Katarina Kayle Kha’Zix LeBlanc Lee Sin Leona Lucian Lulu Lux Malphite Maokai Master Yi Miss Fortune Mordekaiser Morgana Nautilus Nidalee Pantheon Pyke Quinn Renekton Riven Ryze Sivir Sona Soraka Thresh Tristana Tryndamere Tisted Fate Twitch Varus Vayne Veigar Vel’Koz Vladimir Wukong Xayah Zed
