Fortnite’s upcoming Kingdom Key weapon has received a more detailed gameplay leak ahead of the Kingdom Hearts crossover, with datamined values pointing to melee attacks, Thunder magic, aerial movement and a healing mechanic. Fortnite leaker SpushFNBR shared the findings while crediting dataminer Wenso, who has previously uncovered information about the weapon from the game’s files. Epic Games has not published these numerical values, so they should be treated as datamined specifications that could still change before or after release.
According to the leak, the Kingdom Key’s primary attack deals 40 damage, while its secondary Thunder ability deals 60. An air dash is listed at 35 damage, and the weapon apparently supports air combos rather than limiting players to simple grounded swings. The files also indicate that the Kingdom Key uses durability, meaning players may not be able to rely on it indefinitely during a match.
Those details substantially expand on what Epic has shown publicly. Fortnite’s Kingdom Hearts trailer already appeared to show the Kingdom Key casting Thundaga, along with close-range melee attacks and a fast movement ability. At the time, however, Epic had not revealed the damage values, durability rules or any description of how those individual actions would function statistically.
The most uncertain part of the new datamine concerns “Healing Orbs,” which are apparently referenced alongside the weapon. SpushFNBR suggested they may provide healing after an elimination, but that interpretation has not been confirmed and the underlying mechanic could work differently in the live game. It is therefore safer to treat healing orbs as a referenced feature of the Kingdom Key rather than assume exactly how they are generated or collected.
The leaked air-combo support also suggests the Kingdom Key will be more mechanically involved than a standard Fortnite melee weapon. Combining airborne attacks with a damaging dash could allow players to close distance, continue pressure after launching or jumping toward an opponent and then transition into additional swings. Whether those actions consume durability differently, have cooldowns or can be chained indefinitely is not yet clear.
The latest information follows earlier datamining that identified unique elimination-feed text associated with the weapon. Fortnite’s files include references to both the Kingdom Key and Thundaga elimination messages, reinforcing the idea that the Thunder ability is treated as a distinct source of damage rather than purely a visual effect attached to the weapon. Epic has still not released a complete official ability breakdown.
The Kingdom Key itself has been confirmed by Epic as part of Fortnite Chapter 7 Season 4: Override. The season announcement specifically identified the Kingdom Hearts weapon as one of the crossover items coming later in the season, while subsequent material revealed Sora, Riku, Kairi and Roxas as part of the collaboration. The Kingdom Hearts crossover is set for September 17, placing the newly datamined weapon details immediately ahead of its expected arrival.
Epic’s crossover trailer has already established that the Kingdom Key is more than a cosmetic recreation of Sora’s weapon. Players can visibly use it in combat, and the combination of melee swings, magic and mobility makes it closer to Fortnite’s more elaborate Mythic-style crossover weapons than an ordinary harvesting tool. The leaked numbers provide the first clearer indication of how those different functions may be balanced against one another.
A 40-damage primary attack would make repeated melee hits necessary against a fully healthy opponent, while the reported 60-damage Thunder attack would offer a stronger secondary option. The 35-damage air dash appears weaker in raw damage but could have greater value as a movement and combo tool. Without confirmed attack speed, cooldowns, durability totals or Thunder recharge behavior, though, the numbers alone are not enough to determine how powerful the Kingdom Key will be in actual matches.
Epic Games may adjust any of these values before the weapon becomes available. For now, the datamine indicates a 40-damage primary attack, 60-damage Thunder ability, 35-damage air dash, aerial combos, durability and some form of healing-orb functionality. The final live-game implementation should become clearer once the Kingdom Hearts update arrives and Epic publishes or exposes the weapon’s complete in-game statistics.
