Use the fields visible on your own hero cards to choose active slots, keep useful duplicates, and avoid replacing a strong hero just because a new pull looks rarer.
Recent footage shows heroes entering the Backpack with a visible Power value and equipped heroes occupying limited active slots. Keep all slots filled, compare each new pull with the weakest equipped card, and swap only when the new Power is higher or a visible special effect justifies the change.
Power is the safest first comparison because it is displayed in game. Rarity describes how unusual a pull is; it does not by itself prove that the card beats your current weakest slot. Compare the live number before equipping.
Only equipped heroes are shown fighting in current gameplay. An empty slot wastes potential damage, while a strong card left in Backpack contributes nothing to the active team. Unlock and fill slots before chasing a perfect single pull.
The observed Index UI tracks both heroes and enemies and says discoveries award Index Gems. A lower-Power new discovery can therefore still matter for Index progress even when it should not replace an equipped hero.
Record the hero name, Power, rarity, mutation/size or star state if shown, and whether it is equipped.
Compare the new Power with the lowest equipped Power. Do not dismantle or filter anything yet.
Equip a clear upgrade. Keep matching duplicates together if Fusion is available or close to unlocking.
Configure Auto Roll deletion only for pulls you no longer need for active slots, Index discovery, or matching Fusion copies.
A current Gamepur guide places the Fusion Machine in Dark Forest and reports that Fusion requires matching hero identity, mutation, and star level. It reports combining ten matching copies into one higher-star hero with a 1.5× DPS multiplier.
Those counts and multipliers are third-party, dated August 10—not official Roblox documentation. Use them as a preparation checklist, then trust the live Fusion Machine if its requirement differs after an update.
Practical consequence: do not auto-delete all weaker duplicates once Fusion is in reach. Separate exact matches from unrelated low-Power pulls.
| Reason | Keep when | Do not assume |
|---|---|---|
| Active Power | It beats the weakest equipped slot | Higher rarity always means higher Power |
| Index discovery | It is a new hero or mutation entry | Index completion makes it combat-best |
| Fusion copy | Name, mutation and star level match the live machine requirement | Any duplicate can be fused together |
| Enchant target | It remains a core active hero after the upgrade | Every enchant is permanent or equally valuable |
Rank the values actually shown in your Backpack.
Decide when duplicates should become long-term upgrades.
Use rankings only when their hero fields and patch evidence are visible.
