Effect: +15% Crit Chance (stackable per copy). Crits have a 14% chance to become Megacrits, dealing significantly increased damage.
Unlock: Available from the start - no unlock required
Giant Fork is a Legendary item with two effects. First, it gives +15% Crit Chance - and unlike Demonic Blade or Grandma's Secret Tonic, the wiki explicitly notes this bonus is granted every time a copy is obtained, not just on the first. Picking up three Giant Forks gives +45% Crit Chance total. Second, each Crit has a 14% chance to become a Megacrit, which applies an additional catastrophic damage multiplier on top of the normal crit.
Megacrits fire on top of Overcrit math. If your Crit Chance is already over 100%, you are already getting recursive crit multiplications on every hit. A Megacrit from Giant Fork then applies its bonus on top of those stacked multipliers, creating the extremely large damage numbers that crit builds are known for in Megabonk late game.
Note that a Megacrit bug was fixed in patch v1.0.64 (the H A T S update). If you played before that patch and felt Giant Fork underperformed, the fix means it now functions as intended.
The wiki explicitly confirms that the Overpowered Lamp does not grant extra chances for Crits to convert to Megacrits when used alongside Giant Fork. Despite the Overpowered Lamp working with Grandma's Secret Tonic (which has a similar on-crit trigger condition), Giant Fork is a confirmed exception. Do not invest in Overpowered Lamp expecting it to boost Megacrit frequency.
Understanding Megacrits requires understanding Overcrit first. When Crit Chance exceeds 100%, the overflow becomes a probability to crit again on the same hit. At 150% Crit Chance, every hit crits once and has a 50% chance to crit a second time. At 200%, every hit crits twice. Each recursive crit applies the Crit Damage multiplier again, so damage scales exponentially rather than linearly.
Megacrits sit on top of this system. A Megacrit applies a further damage multiplier after the Overcrit math resolves. Additionally, every 10% of Crit Chance over 100% gives a flat 0.1% bonus Megacrit chance on top of Giant Fork's 14% base - so at 200% Crit Chance you have 14% + 10% = 24% Megacrit chance from combined sources.

Giant Fork is available from the start with no unlock required. As a Legendary item it appears less frequently than Common and Rare items, but no quest or Silver purchase is needed before it can appear in chests and from the Shady Guy NPC.
CL4NK - The wiki explicitly names CL4NK as pairing perfectly with Giant Fork. His Crit Happens passive grants +1% Crit Chance per level, stacking directly on top of Giant Fork's +15% per copy. By level 30, CL4NK has added 30% Crit Chance from his passive alone. Combined with one or two Giant Forks, Precision Tome, and Revolver's own Crit Chance upgrades, CL4NK can reach 100%+ Crit Chance reliably and start triggering Overcrits and Megacrits consistently from the mid-game onward.
Dicehead - Dicehead's Gamba passive rolls dice on each level-up, permanently increasing his Crit Chance when he rolls a 6. Multiple Dicehead build guides - including the dedicated Dicehead guide on megabonk.org - explicitly state that Giant Fork is "build-defining" for Dicehead and that without it he is B-tier at best. As Dicehead's permanent Crit Chance accumulates throughout a run, each stack makes Giant Fork's 14% Megacrit window fire more often. The Dice weapon itself also gains permanent Crit Chance from rolling 6s, creating two parallel crit stacking sources that both feed into Giant Fork.
Ninja - Ninja's passive includes a Crit-based execute mechanic and +0.5% Evasion per level. The wiki lists Katana as one of the weapons with both Crit Chance and Crit Damage upgrades, and Ninja's high-speed melee playstyle generates many hits per second with Katana. More hits per second means more independent 14% Megacrit rolls, and Ninja's execute passive fires alongside Megacrits when they land on low-HP enemies - two finishing mechanics operating from the same high-crit-rate build.
It gives +15% Crit Chance per copy (stacking with every copy you pick up) and gives each Crit a 14% chance to become a Megacrit dealing significantly increased damage. Megacrits apply on top of Overcrit math. A bug affecting Megacrits was fixed in v1.0.64. Overpowered Lamp does not boost the Megacrit conversion chance - this is a wiki-confirmed exception.
Yes, fully. Each copy gives +15% Crit Chance and an additional independent 14% Megacrit conversion chance. The wiki explicitly notes this as different from Demonic Blade and Grandma's Secret Tonic, which only give their Crit Chance bonus once regardless of how many copies you hold.
A Megacrit is an enhanced version of a critical hit that applies an additional damage multiplier on top of normal crit damage. Giant Fork gives a 14% chance to convert Crits into Megacrits. Crit Chance over 100% also gives a 0.1% Megacrit chance per 10% of excess Crit Chance. Megacrits apply after Overcrit math, meaning they can fire on top of already-multiplied Overcrit damage.
No. The wiki explicitly confirms Overpowered Lamp does not grant extra chances for Crits to convert to Megacrits when used with Giant Fork. This is a confirmed exception - Giant Fork is in the small group of items that look like they should work with the Lamp but do not.
