Angel Legion: How to Transpose Red SS Heroes to S Heroes

In Angel Legion, you can transfer a high Red-tier promotion rank from an SS hero to an S hero using the hero Transpose system. Transposing performs a direct, mutual rank exchange between two characters rather than resetting materials, allowing you to shift stars to an S hero you can actively promote without sacrificing your prior duplicate shard investments.

How Transpose Works Between SS and S Units

Unlike a standard hero reset that refunds leveling materials and returns a hero to base level, Transposing leaves promotion progress intact. When you select a Red SS hero as the source and an S hero as the target, the two units swap star tiers:

The SS hero retains its rarity but drops to the lower rank formerly held by the S hero. Meanwhile, the S hero inherits the Red promotion tier and immediate combat rating boost.

Prerequisites Before Transposing

The game interface restricts heroes from conversion if they are tied up in active roster duties. Verify these three conditions before opening the conversion menu:

• Unlock Characters: Both units must be unlocked in your hero archive. The system prevents locked heroes from being selected.
• Clear Active Formations: Remove both heroes from defense formations, dispatch assignments, and expedition teams.
• Prepare Currency: Executing the transfer requires payment, typically in Diamonds or designated Transposition items. Check your balance to confirm you can afford the fee shown in the interface preview.

When to Shift Red Stars to an S Hero

SS heroes feature higher base attribute growth per star than S heroes. However, advancing an SS hero through Red star milestones requires scarce SS duplicate gene shards. If your SS carry stalls due to a lack of duplicates, your squad's overall progress can freeze.

S heroes appear more frequently in standard summons and faction shops. By swapping your Red star rank to an S hero with available duplicate shards, you can resume pushing through level caps and breakthrough milestones immediately. While the S hero will have slightly lower raw base stats than an SS hero at the exact same Red tier, their accessible duplicate copies and combat utility make them an effective primary carry when SS shards are unavailable.

Step-by-Step Transposition Process

Follow these steps to complete the transfer:

1. Unequip Sensitive Gear: Remove high-value specialized chips or custom equipment to ensure gear sets do not get misplaced during the tier swap.
2. Access the Menu: Open the hero management screen and navigate to the conversion or laboratory tab to select Transpose.
3. Set Heroes: Place the Red SS hero into the primary source slot and the S hero into the receiving target slot.
4. Review the Preview: Verify that the S hero is slated to receive the Red star rank, check the resulting level caps, and confirm the Diamond fee.
5. Confirm the Swap: Finalize the transaction, re-equip your newly elevated Red S hero, and assign them back to your main formation.
