About

Fortnite's loot pool contains over 80 distinct weapons across 6 rarity tiers, each with different damage multipliers, fire rates, and effective ranges. Selecting the right loadout requires understanding DPS calculations: DPS = Damage × FireRate. This generator uses weighted probability distributions that mirror actual in-game loot spawn rates. Common items appear at 25.5% probability while Mythic weapons drop at just 2%. The tool covers weapons from Chapter 1 through Chapter 5, including vaulted and unvaulted variants.

Use this for challenge runs, creative mode loadout planning, or settling arguments about which random kit wins. The generator supports single weapon rolls, full 5-slot loadout generation with no duplicates, and filtered rolls by weapon type or rarity. Stat bars are normalized against the highest value in the dataset for accurate visual comparison. Note: damage values reflect base stats without headshot multipliers or damage dropoff at range.

Formulas

The generator determines weapon rarity using a weighted probability distribution that models in-game loot spawn rates. Each rarity tier r has an assigned weight w_r, and the selection probability is computed as:

P(r) = w_rn∑i=1 w_i

Where w_Common = 25.5, w_Uncommon = 24.5, w_Rare = 22, w_Epic = 16, w_Legendary = 10, w_Mythic = 2.

Damage Per Second is calculated from base weapon stats:

DPS = BaseDamage × FireRate

Where BaseDamage is the per-hit damage value in HP and FireRate is shots per second. Stat bars use min-max normalization:

BarWidth = value − minmax − min × 100%

Where min and max are the global extremes across all weapons in the dataset for each stat category.

Frequently Asked Questions

The generator uses cumulative distribution function sampling. A random float between 0 and 1 is generated, then mapped against cumulative rarity thresholds. Common weapons occupy 25.5% of the probability space (0-0.255), while Mythic weapons occupy only 2% (0.98-1.0). This mirrors actual Fortnite loot chest distributions where higher rarity items are exponentially rarer.

Fortnite applies a consistent damage scaling multiplier per rarity upgrade. Typically each tier increases base damage by approximately 5-10%. For example, a Common Assault Rifle deals 30 damage while the Legendary variant deals 36 - a 20% total increase over 4 tiers. The generator stores the full rarity-damage curve for each weapon and selects the appropriate value based on the rolled rarity.

Yes. The full loadout mode uses Fisher-Yates shuffle on the filtered weapon pool and draws 5 unique weapons sequentially. By default it also enforces slot diversity: no more than 2 weapons of the same type (e.g., you won't get 3 ARs). This constraint can be toggled off for pure random chaos loadouts.

The dataset includes both currently available and vaulted weapons spanning Chapters 1-5. You can filter by availability status using the "Include Vaulted" toggle. Vaulted weapons are marked with a vault icon on the weapon card. This is useful for Creative mode planning where all weapons are accessible regardless of vault status.

Burst weapons like the Burst AR fire 2-3 round bursts with inter-burst delay. The listed fire rate represents effective rounds per second accounting for burst delay. For a 3-round burst at 1.75 bursts/second with 27 damage per round, effective DPS equals 27 × 3 × 1.75 = 141.75. The generator uses this effective rate, not raw cyclic rate.

Yes. Each generated weapon card has a "Save as PNG" button that renders the card to an HTML5 Canvas element and triggers a download via canvas.toBlob(). The exported image is 600×400 pixels at 2x resolution for high-DPI displays. Loadout exports combine all 5 weapon cards into a single panoramic image.
