Welcome to the METAsrc Teamfight Tactics Double Up Jax build guide. We've used our extensive database of League of Legends TFT Double Up match stats and data, along with proprietary algorithms to calculate the best build options for Jax, including item builds, best team comps, spatula items, and trait synergies. We've also compiled useful stats, such as win rate, top 4 rate, pick rate, average placement, level, and score. We've also included in-game stats, such as ability, health, power, attack damage, spell power, armor, magic resist, attack speed, range, crit chance, and crit bonus. Use it as a reference to assist with gameplay decisions.
