Ammo

Overview

Ammo in Windrose covers the firearm projectiles and gunpowder used by Pistols, Muskets, and Blunderbusses, plus one unique item (Pearl) that is catalogued as ammo but is actually an alchemy reagent. Firearm bullets roll out across three quality tiers: baseline Stone, mid-tier Copper and Iron, and a rare top-tier Bullet Arborum. Gunpowder is its own supply chain, powered by the Millstone once Sulfur and Ash are flowing.

The six items below are the full ammo roster in version 0.10.0. The damage modifier column is the headline stat that most affects which bullet you load: baseline Stone Bullets actually reduce damage, Copper is even, Iron adds a flat 10%, and Bullet Arborum converts that into a 30% boost to critical damage. Pearls sit in the ammo category but are consumed at the alchemy station for Elixir of Cruelty, not fired.

Damage Modifiers Explained

The in-game tooltip for each bullet tells you exactly how the projectile interacts with firearm base damage. Stone Bullets apply a penalty of 20%, Copper Bullets are neutral with mediocre ballistics, Iron Bullets add 10% Ranged Damage, and Bullet Arborum shifts the bonus onto critical damage at 30%. Because the modifier scales off the firearm's own roll, a higher-tier bullet paired with a Reliable Musket or Drake's Double-Barreled Pistol benefits far more than the same bullet fired from a worn starter weapon.

Ballistics is the other axis the tooltip calls out. Poor, Mediocre, Good, and Excellent correspond to how tightly the ball tracks toward your reticle at range. Stone Bullets only hit reliably at close range, Copper is passable, Iron is accurate enough for mid-range engagements, and Bullet Arborum is the only round that stays on target for long shots.

Gunpowder Supply

Every firearm shot consumes one Gunpowder regardless of which bullet you load, so Gunpowder is the more dangerous bottleneck than bullets themselves. Early game you rely on loot: pirate camp crates and the Tortuga Goods Seller both carry small amounts (vendor price: 2 Piastre per unit), and Blackbeard Crew Chests in Pirate Camps are the most reliable respawning source.

Once Foothills access opens and Sulfur starts flowing, the Millstone crafts 10 Homemade Gunpowder per 45-second cycle from 10 Sulfur and 20 Ash. See the Gunpowder article for the full crafting chain and conservation principles.

Construction Use

Homemade Gunpowder is not only a combat consumable. It is also a construction material: each Explosive Barrel station requires 40 Homemade Gunpowder to build. Players planning ship boarding raids or base defenses should plan Millstone output around both combat and construction demand.

Progression Path

A typical ammo progression follows the biome unlocks. Stone Bullets carry you through the Coastal Jungle since stone piles are on every road. Copper Ingots become routine as you start dungeoning, so Copper Bullets smooth out the mediocre accuracy of Stone without a real damage change. Iron Bullets are the workhorse from the Foothills biome onward because the 10% Ranged Damage boost applies to every firearm simultaneously. Bullet Arborum is a late-game luxury: keep a small stack reserved for bosses and elite pirate officers where the critical damage bonus pays off the expensive Ingot Arborum cost.
