Jax is one of the new playable Champions added to the Path of Champions PvE Lab Mode in Legends of Runeterra's Awakening update. It's obvious that Riot is building towards some big world-building event in Runeterra, and this expansion is another step towards that. Alongside seven other newly playable Champions, Jax's general tactics and starting deck incorporate a lot of the new Keywords, specifically Improvise and Equip.
