Quick overview

Evolving Aurin gives the Nuclear Giant variant. The evolved form remains a mythic rarity but is generally treated as a lower competitive pick. The process requires specific materials and gold. Use this guide to gather items efficiently and evaluate whether evolving Aurin matches your roster goals.

Evolution requirements

Collect all of the following before starting the evolution:

• Colossal Spine × 12
• Green Essence × 30
• Blue Essence × 30
• Red Essence × 10
• Yellow Essence × 10
• Rainbow Essence × 1
• Gold cost: 15,000

Tip: Colossal Spines commonly drop from higher-difficulty or legend-level stages. Essences are earned via challenge rewards, shops, and repeatable content.

Step-by-step evolution process

• Open the upgrades area and access the Upgrades / Evolve station.
• Choose Aurin from your roster in the evolution interface.
• Verify you have every required item and the gold cost.
• Confirm and press the evolve button to transform Aurin into Aurin (Nuclear Giant).
• After evolving, review trait and stat values, and reassign familiars or placement as needed.

Best practice: raise the base form’s stats before evolving so the evolved unit begins with higher effective power.

Key evolution notes

• There is no takedowns requirement for this evolution; only materials and gold are needed.
• Traits and familiars persist after evolution; plan rerolls prior to evolving if you want a specific trait to carry over.
• The evolved Aurin grants a temporary placement buff zone. Its value depends on roster synergy and placement strategy.

Tier and competitive value

Aurin (Nuclear Giant) is usually ranked as Tier C among mythic units. It is not a top-meta damage carry but can provide situational utility, especially for teams that can exploit its placement buff. Prioritize evolving higher-tier units if materials are limited.

Practical tips to improve your gameplay and roster

• Prioritize meta carries: Spend materials on proven high-impact units before niche evolutions.
• Max base stats first: Upgrade a unit’s base form to get stronger evolved stats.
• Pick complementary traits and familiars: Traits greatly change a unit’s value; aim for synergies.
• Farm legend stages efficiently: Repeat the stages that drop the items you need most.
• Practice placement and synergy: Position units to take advantage of auras, buff zones, and support effects.
• Compare cost vs reward: Only evolve when the expected utility justifies the material and gold cost.
• Follow community tier lists: Check up-to-date guides after major updates before committing resources.

Suggested roles where Aurin helps

Use Aurin (Nuclear Giant) as a supporting anchor in lineups that benefit from temporary placement buffs or short cost reductions. It performs best when paired with reliable damage dealers that can capitalize on the buff zone.

Frequently asked questions

Can every unit evolve?

No. Only specific eligible rarities and units have evolution paths. Check each unit page or your upgrade menu for availability.

Do I need kills or takedowns to evolve Aurin?

No. This evolution requires only the listed materials and gold; there is no takedowns threshold for Aurin.

Will traits or familiars be lost on evolution?

Traits and familiars carry over into the evolved form. If you want a particular trait, secure or reroll it before evolving.

Is evolving Aurin worth it given its Tier C ranking?

It depends on your roster and goals. If Aurin fills a specific utility gap for your lineup, evolving may be worthwhile. If you lack materials and have stronger units waiting, prioritize those instead.

Where should I farm Colossal Spine and essences?

Focus on legend-level and high-challenge stages that list the needed drops. Repeat the most efficient stage for each material to increase drop rates per hour.

How often should I check tier lists?

Review tier lists and patch notes after major updates. Meta shifts are common when new units or balance changes arrive.
