Required Evolution Materials & Where to Farm Them
Evolving Zoro requires a dedicated collection of upgrade items and elemental resources. These materials are primarily gathered by playing specific game modes, clearing raids, or redeeming active Universal Tower Defense Z Codes released during major update patches.
Below is the complete material checklist required to complete the evolution process:
| Material Name | Quantity Required | Primary Acquisition Method |
|---|---|---|
| Triple Threat (Base) | 1 | Summoning (Gems / Tickets) |
| Ocean Fragments | 10 | Water-themed Raids / Event Challenges |
| Sky Fragments | 10 | Air-themed Raids / Virtual Realm |
| Universal Fragments | 5 | World Raids / High-Wave Infinite Mode |
| Gold | 50,000 | Story Progression / Daily Challenges |
Keep an eye on active event modes. Limited-time events often provide double fragment drop rates, making it much faster to farm the Ocean and Sky fragments needed for Zoro's evolution.
Step-by-Step Zoro Evolution Guide
Follow this precise sequence to successfully evolve your base Zoro into his Unrivaled state. Make sure your account has reached the necessary level requirements and that you have cleared the early stages of Story Mode to unlock the Evolution Menu.
Acquire the Base Triple Threat Unit
Spend your Gems or Summon Tickets at the main gacha banner. Triple Threat is an Epic-rarity unit, making him relatively accessible compared to Mythics. Keep pulling until he is added to your inventory.
Farm the Elemental Fragments
Navigate to the Raids or Virtual Realm portals. Target the specific elemental stages to secure 10 Ocean Fragments, 10 Sky Fragments, and 5 Universal Fragments. You can also check active codes for free material bundles.
Level Up the Base Unit
Take Triple Threat into Story Mode or Infinite runs to increase his base level. While not strictly locked to max level, evolving a higher-level base unit ensures his stats scale more effectively upon transition.
Execute the Evolution
Go to the Evolution NPC in the main lobby. Place Triple Threat into the primary slot, select the required fragments from your inventory, pay the 50,000 Gold fee, and confirm the evolution to receive Triple Threat (Unrivaled).
Once evolved, Triple Threat (Unrivaled) gains a massive spike in base attack power, a wider attack cone, and a unique passive that inflicts stacking bleed damage on bosses.
Triple Threat (Unrivaled) Build and Strategy
Now that you have successfully completed the evolution, you need to optimize Zoro's build to dominate high-wave Infinite runs and co-op World Raids. Because Zoro relies heavily on rapid physical slashes and bleed damage over time, your build priority should focus on speed and raw damage.
Optimal Traits
- Reaper: Increases overall damage output.
- Godly: Provides massive stat boosts across all categories.
- Swift: Lowers cooldowns to stack bleed faster.
Stat Reroll Priority
- Attack Speed: Higher speed means faster bleed application.
- Critical Chance: Essential for landing heavy physical hits.
- Range: Expands his AOE swing radius on tight corners.
Team Synergy
- Bulmo: Provides the early economy needed to place Zoro.
- Virtual Idol: Buffs his damage and range mid-game.
- Sasku: Complements Zoro with defense-shredding debuffs.
Place Triple Threat (Unrivaled) at major bends or U-turns on the map. This positioning allows his wide-angle sword slashes to hit the maximum number of enemies per swing, maximizing his bleed application.
