Legend of YMIR Mythical Companion Fusion and Preparation Guide

To unlock a Mythical Companion in Legend of YMIR, you must accumulate and combine duplicate Legend companions through the fusion menu using large reserves of gold. Companions provide auto-looting in open-world hunting zones and dungeons while passively boosting your Combat Power (CP). Mythical-tier companions add high-value secondary stats, including critical hit chance, skill damage reduction, bonus gold gain, and monster hunting experience, significantly lowering potion usage during sustained field farming.

Companion Fusion Mechanics and Tier Requirements

Companions advance through rarity tiers via percentage-based synthesis. Combining duplicates offers a chance to ascend to the next rarity tier or awards combine mileage and compensation tokens toward pity thresholds if the attempt fails.

Never sacrifice your primary equipped companion in a fusion attempt. If a combine fails, losing your active pet reduces farming speed and loot pickup efficiency. Only fuse spare duplicates once your main hunting pet is secured.

Codex Registration Order for Maximum Combat Power

Every unique companion registered in the Companion Codex grants permanent, account-wide stat bonuses regardless of which pet is currently active. Registering a duplicate into an incomplete codex slot often provides more immediate, guaranteed CP than risking that duplicate on a low-percentage fusion gamble.

Prioritize codex stat categories in this order:

1. Accuracy and Penetration: Hitting higher-level monsters without glancing blows is the primary bottleneck for grinding efficiency. Complete Accuracy collections first.
2. Defensive Stats (Health and Damage Reduction): Flat damage reduction and bonus health allow your character to survive in higher-level hunting grounds without excessive potion consumption.
3. Offensive Amplification (Critical Rate and All Damage): Once baseline accuracy and survivability are stabilized in your farming zones, finalize collections that increase critical chance and damage output.

Check your codex before executing bulk fusions to ensure low-tier duplicates are not destroyed before completing cheap stat collections.

Resource Stockpiling Checklist

Preparing for Mythical fusion attempts requires deliberate inventory management:

• Save Companion Summon Tickets: Hold summon tickets and premium chests obtained through maintenance rewards, daily achievements, and event shops. Using them during companion updates ensures chances at expanded pools and event mileage.
• Accumulate Gold Reserves: Combining high-tier companions requires tens of millions of gold. Avoid depleting gold balances entirely on gear crafting or skill upgrades before running fusion sessions.
• Retain Spare Legends: Mythical fusion attempts require multiple spare Legend-grade pets. Keep your primary farming companion locked and separate from your synthesis materials.
