What Fusion Does
Fusion is one of the two ways to raise a hero past the version you rolled. The official Roblox listing for Heroes RNG 🏹 states it plainly: “Fuse & Enchant them to make them more powerful!” — and unlike a seasonal event, it is listed as permanent.
It arrived in the UPD 3.2 Fusion update, when the experience carried the [FUSION] tag and PCGamesN reported new heroes shipping with it. That means fusion is the older, better-documented system of the two, while enchanting was only written into the description in August 2026.
How to Fuse Heroes
The four steps, in order.
Open your hero roster
Fusion acts on heroes you already own, so start from the roster screen rather than the roll station.
Select two heroes you are willing to lose
Fusing combines owned heroes into something stronger. Treat both inputs as spent — never fuse your only copy of the hero carrying your team.
Open the fuse action for that pair
The developer lists fusion as a core system on the official Roblox page ("Fuse & Enchant them to make them more powerful!"), so the action ships with the game rather than as a limited event.
Confirm and check the result
After the fuse, compare the outcome against the inputs. Because Heroplay does not publish a recipe table, testing on spare duplicates is the only reliable way to learn the ladder.
Fusion vs Enchanting vs “Crafting”
Three words, two documented systems.
Fusion
Confirmed systemCombines owned heroes into a stronger unit. Shipped as the headline feature of the UPD 3.2 Fusion update — Pro Game Guides and Try Hard Guides both carried the [FUSION] tag in their titles and PCGamesN reported new heroes alongside it. It is now permanently named in the official description.
Enchanting
Confirmed systemA second power-up path applied to a hero, listed beside fusion in the official description. Costs, tiers and failure rules have never been published.
Crafting
Community phrasingPlayers and some code pages say "crafting" when they mean fusing. There is no separately documented crafting bench in Heroes RNG — if a guide promises crafting recipes, check whether it is describing fusion under another name.
Artifacts are a third upgrade track but not a hero action — they drop from bosses. Read the enchanting & artifacts guide →
Fusion Mistakes That Cost Runs
Cheap insurance before you press the button.
- Fusing your only Legendary or your main damage dealer to "test" the system — the roster weakens immediately and the result is not guaranteed to be better for your team.
- Fusing before you bank Gold for upgrades — fusion does not replace the roll-and-upgrade loop, and a thinner roster makes the next zone harder to clear.
- Trusting a "fusion recipe chart" with exact rarity outcomes. Heroplay has not published one; charts circulating online are player experiments.
- Fusing away duplicates that a future requirement might need. Spare heroes cost nothing to hold.
Still Unannounced
- — No official fusion recipe table, success rate, or rarity floor.
- — No published Gold cost for a fuse, and no statement on whether fusion can fail.
- — Whether an enchantment carries over through a fusion is undocumented.
- — No developer statement on whether fusion results depend on the two input heroes, their levels, or both.
Fusion is confirmed; its numbers are not. We publish mechanics only once Heroplay Studios or a named authority states them, and re-check the official listing with every weekly update.
