In Omniheroes, you can exchange surplus duplicate Legendary heroes for alternative heroes of the same rarity and faction pool. This conversion feature rerolls unneeded copies into potential synergy partners without downgrading unit rarity.
Conversion requires unlocked heroes and dedicated conversion currency, making it an option primarily for mid-to-late game accounts that have already established baseline roster depth.
Step-by-Step Hero Conversion Procedure
Before starting a conversion, verify that the hero is not currently locked, equipped, or assigned to active formations.
- Unequip and unlock the hero: Open your Hero Bag, locate the duplicate unit, remove all gear, runes, and artifacts, and deselect the lock icon.
- Open the conversion menu: Navigate to the Sanctuary or Hero Management interface and select the Hero Conversion tab.
- Insert the sacrifice card: Place the unlocked duplicate into the conversion slot and verify the eligible faction outcome pool displayed on screen.
- Pay the conversion cost: Confirm you have the required conversion tokens or exchange currency specified by the menu.
- Roll and decide: Initiate the conversion. If prompted, compare the newly rolled unit against your original hero and confirm your final selection.
Which Heroes to Convert
Because conversion consumes currency and forfeits guaranteed star-ascension fodder, reserve the system for truly redundant units rather than heroes you still need to build.
| Hero Type | Recommended Action | Rule |
|---|---|---|
| Max-Star Duplicates | Convert immediately | Heroes at maximum star ascension gain no further benefit from duplicate copies. |
| Off-Meta Regular Legendaries | High conversion priority | Units with weak synergy passives rarely justify star investment over core synergy partners. |
| Unbuilt Core Synergy Units | Hold in reserve | Keep units belonging to core synergies (such as Mystifiers, Doomsdayers, Ethereals, or Valiantors) for team thresholds. |
| Royals / Rare Factions | Never convert | Premium units have exceptionally low drop rates; do not sacrifice them in standard conversions. |
Managing Ascension vs. Conversion Costs
Every conversion consumes duplicate cards and dedicated tokens that could otherwise support guaranteed star promotions. Prioritize standard star ascension if your account still needs raw combat power to clear campaign stages or Rift Odyssey floors. Guaranteed promotions provide reliable stat gains that outweigh random rerolls.
Shift toward active conversion only when raw star promotions reach diminishing returns and progression stalls due to missing synergy keystones. In addition, avoid converting unique Legendary heroes you do not yet own in duplicate; account systems like Sanctuary resonance scale with the variety and star levels of unique heroes registered to your collection.
