Hero Clash: How to Upgrade S+ Heroes to Eternal Tier

To upgrade an S+ hero to Eternal tier in Hero Clash, you must advance the character through intermediate awakening stages using identical S+ duplicate copies and matching faction fodder. Reaching Eternal eliminates intermediate level caps, boosts base attribute scaling, and unlocks peak exclusive equipment performance.

S+ Awakening Progression Path

Awakening requires advancing through fixed tier thresholds. You perform these merges at the Hero Temple or Hero Awakening altar in the main city hub.

Upgrade Procedure

1. Lock all essential heroes in your inventory to prevent them from autofilling as sacrifice materials.
2. Open the Hero Temple or Awakening altar from the city hub.
3. Choose your Transcendent+ S+ hero as the base upgrade target.
4. Fill the sacrifice slots with the required S+ duplicate copies and designated faction fodder.
5. Confirm the merge prompt to finalize the Eternal rank.

Fodder and Resource Management

Acquiring sufficient lower-tier fodder is often the primary bottleneck when moving from Transcendent to Eternal. Efficient resource management prevents your progress from stalling:

• Target one carry at a time: Direct all faction summon tokens into the specific faction of your chosen carry. Concentrating on one unit maximizes your intake of same-faction A-tier heroes, which are required to build Epic+ and Legendary fodder.
• Rely on A-tier units for fodder: Evolve base A-tier heroes to meet fodder rank requirements. Avoid sacrificing standard S-tier heroes unless your main team is fully built and the copies are completely redundant.
• Save summon scrolls for events: Spend standard scrolls and faction tokens during server summon events that feature milestone reward chests.
• Hold selective hero cards: Keep faction selection chests in reserve until you need the final duplicate copy to cross an awakening threshold.

Costly Mistakes to Avoid

• Splitting S+ duplicates: Spreading duplicate chests across multiple S+ damage dealers leaves your account with several low-tier units rather than one dominant anchor. A single Eternal carry outperforms multiple Transcendent units because higher level caps unlock superior base stats.
• Burning utility heroes: Sacrificing rare S-tier crowd-control or support units for quick fodder limits your team options in faction trials and multi-lineup campaign stages.
• Upgrading without long-term plans: Because S+ copies require significant resources, verify that your target unit serves as an essential primary damage dealer or primary crowd-control initiator before committing duplicates.
