Jax
View on WikiGood (6/10)
Low Investment
Rare Relics OK
Jax is a highly efficient aggressive champion capable of rapid victories in standard encounters. However, his reliance on baseline stats and specific keywords causes him to underperform in late-game challenges where enemy health and damage are significantly inflated. While his low mana cost makes him accessible, the lack of a full constellation limits his long-term viability compared to modern specialized champions.
Aggressive Overwhelm
Exploits Jax's low level-up requirement to generate immediate board pressure and multiple attacks in a single turn.
Provides essential Overwhelm to the entire board, ensuring that the stat buffs from Weaponmasters and Jax's level 2 form effectively damage the enemy Nexus.
Synergizes with Jax's auto-equip mechanic and Forge effects, providing a consistent source of scaling stats that persist across rounds.
Strategy
This build focuses on maximizing Jax's early-game offensive potential. By utilizing Crownguard Inheritance, Jax can often end games the moment he levels up. The Beast Within ensures that the high Power stats generated by his Weaponmaster subtype followers are not wasted on blockers.
Sustained Voltron
Increases Jax's survivability and stat growth as he engages in multiple combats, compensating for his lower base Health.
Consolidates stats and keywords from allies into Jax, allowing him to bypass board space limitations and create a single, unstoppable attacker.
Grants Challenger to all allies, allowing for precise board control and ensuring Jax can strike targets that maximize his level-up progress without dying.
Strategy
This approach is designed for longer encounters where a single strike is insufficient. It focuses on building Jax into a massive unit that can survive multiple exchanges while controlling the enemy board through Challenger.
Other Relic Options
Increases deck consistency by adding more copies of Jax and reducing the cost of his champion spell, which provides necessary protection through Barrier.
Eliminates the risk of Jax dying during an attack, which is critical against high-Power enemies in Nightmare difficulty.
Enables a specific combo to draw high-impact cards or support champions at zero cost, facilitating faster board development.
Jax has high flexibility with Rare relics, making him a strong choice for players who have not yet optimized an Epic relic collection.
Constellation
Jax currently lacks a full constellation beyond three stars. This results in a performance ceiling where he remains dominant in 3-star and 3.5-star adventures but struggles to compete with champions who possess 4 to 6-star upgrades. His primary strength lies in his cost-effective aggression and the Weaponmaster origin.

Last Light of Icathia
Allies have "Attack: Grant me +1|+0. If I am equipped, also grant my equipment +1|+0."
Relentless Assault
+1 Starting Mana. When an equipped ally dies, draw 1.
Last Light of Icathia II
Allies have "Attack: Grant me +1|+1. If I am equipped, also grant my equipment +2|+0."
Gameplay Tips
- Manage Equipment Hand Space
Jax's mechanics frequently return equipment to the hand when allies die or are replaced. It is essential to monitor hand size to prevent burning critical draws or champion spells.
- Optimize Level-Up Timing
Jax levels up based on the total damage dealt by equipped allies. Prioritize attacking with equipped units early, even if the damage is non-lethal, to trigger Crownguard Inheritance or Tempest Blade at the most strategic moment.
- Utilize Auto-Equip Logic
When Jax is summoned, he will take his Light of Icathia from another ally if it is already on the board. Use this to move the weapon from a weaker unit to Jax for free, preserving mana for other plays.
- Challenger is Mandatory
In higher-tier content, Jax requires a source of Challenger (either from Laurent Bladerack, Chosen by the Stars, or support champions) to ensure he can pick favorable trades and avoid high-Power blockers that would otherwise end his run.
- Synergize with Ornn
As a support champion, Ornn is a premier choice for Jax. Jax's ability to quickly scale a weapon early in the game allows Ornn to copy a massive equipment, providing a secondary win condition for longer matches.
