A newly documented glitch in The Legend of Zelda: Ocarina of Time is giving speedrunners a fresh reason to re-examine routes that have stood for years. The technique, highlighted by runner ZFG, uses a bottled item at the moment a hitbox disappears. In the right circumstances, the interaction can overwrite damage values, letting Link deal damage normally associated with tools he may not actually have.
Its two clearest uses so far are striking: Volvagia can be defeated without the Megaton Hammer, while Ganondorf can be beaten without Light Arrows. Those are major departures from the game’s expected progression, but they are not a simple “press a button, skip a boss” discovery. The glitch appears to depend on timing, prior setup and how the game is loading and unloading memory. That makes it potentially powerful, yet highly situational.
What the new bottle interaction appears to do
In game-development language, a hitbox is an invisible area the game uses to determine whether an attack, object or character has connected with something. The reported trick requires a bottled item to be used as one of those hitboxes is vanishing. The result can be an overwritten damage value: instead of the expected damage attached to Link’s current action, the game can apply another value.
The important term here is damage value. It is the internal instruction that tells the game how much damage an event should inflict, rather than merely the visual animation on screen. The discovery is compelling because it is not simply a collision exploit that lets Link pass through a wall or evade a trigger. It changes what a successful attack can mean to the game’s combat logic.

ZFG has described the behavior as connected to memory loading and unloading. That is a useful explanation, but it should not be overstated: the currently reported applications do not establish that every disappearing hitbox can be converted into any desired attack. Instead, the early findings point to particular combinations that can produce unusually high-value damage under particular conditions.
One combination currently described as relatively consistent in Ocarina of Time uses Link’s magic spin attack followed by a fairy in a bottle. “Consistent” still does not mean effortless. In speedrunning, a technique must be reliable enough to justify its risks, setup costs and execution demands before it meaningfully changes a route.
Why Volvagia and Ganondorf matter
Volvagia and Ganondorf are not interchangeable targets. Each normally points runners toward a major required tool, so defeating either boss without that tool can remove—or rearrange—a piece of a route’s item progression.
For Volvagia, the possibility of fighting without the Megaton Hammer is especially significant. A route that does not need to collect the hammer may be able to avoid time and movement tied to obtaining it. In randomizer play, where items are placed in altered locations, the impact can be even broader: a player may no longer need the hammer to be accessible before Volvagia is addressed.
Ganondorf without Light Arrows is equally eye-catching as a demonstration of what the damage manipulation can achieve. But a visually dramatic skip is not automatically a record-setting improvement. Runners will need to determine whether the prerequisite actions, resource needs and failure risk beat the time required to follow a more conventional route.
The immediate lesson is that “can bypass a required item” and “saves time in a competitive category” are two different claims.
Why the category impact is uneven
Early discussion suggests the glitch may affect several Ocarina of Time categories, though not equally. That distinction is essential. A speedrun category is defined not just by the game’s ending, but by its rules and route assumptions. A discovery that is useful in one rule set may add nothing in another—or may require a route to be rebuilt around it.
In All Dungeons, the current route reportedly skips both the Slingshot and magic. The bottle glitch needs one of those elements to function, creating an immediate tradeoff. If acquiring the necessary resource costs more time than the boss shortcut saves, the technique is not beneficial. Runners are nevertheless investigating a way to pick up the Slingshot that could improve the Volvagia encounter.
No Wrong Warp appears to be the most immediate candidate for improvement. A wrong warp is a speedrunning technique that redirects a transition to an unintended destination. In a category that prohibits it, normal progression constraints carry more weight. The new damage manipulation could allow runners to avoid the longer process of obtaining magic while collecting the Slingshot instead, a change projected to save several minutes.
Randomizer runs may be the biggest beneficiaries. A randomizer changes where items are found, which means the standard sequence of acquiring tools can no longer be taken for granted. If Volvagia is beatable without the hammer, a seed in which the hammer is late, remote or inconvenient becomes less restrictive. The glitch could therefore offer routing flexibility rather than merely shaving seconds from a fixed route.
What runners need to test next
The first discovery is only the start of the speedrunning process. Before a trick becomes routine, runners typically need to identify exactly which game states permit it, which bottled items work, how narrow the timing is and whether the result behaves consistently across a full run rather than in isolated attempts.
For this glitch, the key practical questions include:
- What specific hitboxes and bottle contents produce the desired damage values?
- Which prior actions are required to arrange the relevant memory state?
- How much time does the setup consume compared with the progression it skips?
- How often does the trick succeed under run conditions?
- Which categories can absorb the new item requirements without losing time elsewhere?
These details matter because a technique can be technically valid but competitively unattractive. An elaborate sequence with frequent failures may be useful for challenge runs, demonstrations or randomizer problem-solving while remaining too risky for a record attempt. Conversely, a method that looks inconvenient at first can become route-defining if runners find a dependable setup and integrate it into existing movement.
Majora’s Mask has an early application too
The same broad behavior has also been reported in The Legend of Zelda: Majora’s Mask. There, using a magic spin and then spring water can generally produce damage associated with a Powder Keg. With setup, that can rapidly break through obstacles on the way to Goron Racetrack and Romani Ranch.
This does not mean the two games have identical applications. The reported bottle contents, targets and outcomes differ, and each game’s routes have their own constraints. What it does show is that the underlying interaction may have relevance beyond one boss skip in one game. That gives runners of both titles a concrete reason to test further, while retaining the caution that the trick’s behavior is currently known to be conditional.
Original hardware and Switch Online are both in the picture
For players curious about the technical side rather than leaderboard implications, the reported compatibility is notable: the trick works on the original cartridge release and on the Nintendo Switch Online version. That makes it more broadly accessible than a discovery limited to a single rare revision or specialized setup.
Accessibility does not make it a casual-play necessity. Most players will have no reason to restructure a normal adventure around a difficult bottle-and-hitbox timing interaction. But for challenge runners and randomizer players, the possibility of treating the hammer or Light Arrows as optional in specific fights is a meaningful new tool.
More than anything, the discovery is a reminder that old games can still produce new technical knowledge. Nearly three decades after Ocarina of Time first arrived, the questions are no longer only whether the trick works, but where it is legal, where it is fast and where it changes the logic of a route altogether.
