To upgrade gear to Mythic quality in Last Z: Survival Shooter, you must fully enhance a Legendary item to its maximum level and spend dedicated promotion materials alongside standard enhancement components and gold. You cannot craft Mythic items from scratch. Because promotional catalysts are scarce and primarily acquired through high-tier alliance rewards, elite shop purchases, and competitive milestones, you must funnel your upgrades into specific gear slots rather than spreading resources evenly.

Core Stat Multipliers by Gear Slot

Promoting equipment from Legendary to Mythic adds flat stat increases along with percentage-based combat multipliers. These percentage values scale with your tech tree, hero star ratings, and vehicle bonuses.

Follow a focused three-phase sequence to maximize duel win rates and high-level PvE clear speeds:

  1. Phase 1: Backline Carry Weapon

Invest your first batch of Mythic materials into the weapon slot of your primary damage carry. Securing early burst damage allows your squad to eliminate enemy frontline tanks before defensive abilities cycle.

  1. Phase 2: Frontline Chest Armor and Helmets

Once your main attacker has a Mythic weapon, direct all materials to the chest armor and helmets of your two frontline units. Upgrading these slots provides percentage damage reduction and health mitigation, preventing your damage dealers from being exposed.

  1. Phase 3: Auxiliary Radar and Secondary Offensive Pieces

Upgrade utility pieces, such as radar and boots, only after your main carry weapon and frontline defenses are secure. These auxiliary slots provide speed and critical bonuses that optimize an already stable formation.

Resource Allocation and Progression Rules

  • Focus exclusively on Squad 1: Never spend Mythic materials on secondary marches until your main five-hero squad has its core weapon and defensive slots upgraded.
  • Keep capped Legendary gear on secondary teams: Leave secondary squads with maxed Legendary equipment rather than fragmenting materials across multiple partial upgrades.
  • Swap gear for specialized content: When solo trials or campaign stages require specific hero setups, move your upgraded Mythic gear directly onto those heroes instead of forging duplicate pieces.
  • Avoid dismantling functional gear: Do not dismantle or reset leveled equipment from secondary teams to rush a single Mythic promotion, as doing so weakens your defensive garrisons during alliance wars and cross-server events.
