Revision 18

Tumbaga Ingot is the weapon ascension material in Windrose. It is used at the Weaponsmith Workshop to ascend a Rare (blue) weapon to Epic (purple) rarity, unlocking that weapon's Epic-tier special effects.

Source

Tumbaga Ingots are found in chests tied to Blackbeard Treasure Maps. Each Blackbeard Treasure Map chest typically contains three ascension ingots. Treasure Maps drop from named encounters and boss-tier enemies in Blackbeard's fleet. The exact drop rate from specific enemies continues to be documented by the community.

Ascension Process

At the Weaponsmith Workshop's upgrade tab, a Rare weapon already leveled to 8 (via the Upgrade System) can be ascended to Epic by consuming Tumbaga Ingots. Ascension grants the weapon new Epic-tier passives on top of its existing stats. For example, a Rare Reliable Musket (+faster reload) becomes an Epic Reliable Musket (faster reload + 20% Critical Damage) after ascension. A Rare Sturdy Halberd becomes Epic with +15% Critical Hit Chance and +15 base damage.

Which Weapons to Ascend

Tumbaga is scarce, so plan ascensions carefully. Good ascension candidates are weapons that scale with your build's primary attribute, already show strong base stats, and have meaningful Rare or Epic effects. The Plague Halberd (Epic version restores 35% of max Health at 5 Corruption stacks) and the Rapier of a Thousand Cuts (bleed stacks with kill-transfer) are standout candidates for ascension.

Uses: Gear Ascension

Tumbaga Ingot has a single use: it is the sole consumable required for Ascending Gear, the mechanic that increases an item's rarity tier and unlocks an additional passive slot on weapons and armor. The full ascension track runs Common to Rare (blue) to Epic (purple) to Legendary, with each step consuming Tumbaga Ingots from the player's inventory. In the current Early Access build the reliably testable step is Rare to Epic; Legendary is referenced in game data and in the community ascension flow but does not yet have confirmed craftable weapons or armor in the live patch, so most Tumbaga spending in practice funds Rare-to-Epic conversions.

Tumbaga is consumed at two different workbenches depending on the item type. Weapons ascend at the Weaponsmith Workshop and armor pieces ascend at the Armor and Clothing Workshop. Both benches expose a dedicated Ascend tab that only unlocks once the target item has been upgraded past a specific threshold at the Upgrading Station, which is covered in the next section.

Iron Stage Anvil Prerequisite

An item cannot be ascended directly out of its base craft. It first has to be fed through the standard upgrade track at the Upgrading Station until it reaches the iron stage of the track. The iron stage is the upgrade threshold that consumes an Iron Ingot and requires an Anvil built at the player's camp. If the camp has no anvil yet, the upgrade slot that would cross the iron threshold is locked and the Ascend tab will not appear on the weapon or armor bench. Players who want to begin ascending gear therefore need to prioritise an anvil in the build order well before spending any Tumbaga.

The full prerequisite chain is: anvil placed at camp, item upgraded to the iron stage at the Upgrading Station (typically continued to level 8 for maximum stats), Tumbaga Ingot in inventory, item carried to the Weaponsmith Workshop or Armor Bench, Ascend tab selected, ingot consumed, rarity ticked up. Missing any link in that chain causes the ascension UI to refuse the action. None of the cheaper material refunds from the Disassembly Table return Tumbaga once it has been consumed, so the chain has to be completed deliberately on the first attempt.

Passive Unlock on Ascension

The defining effect of spending a Tumbaga Ingot on a piece of gear is the passive unlock. Blue-and-above items already carry one passive roll: weapons grant a single active effect (faster reload, stacking Bleed, Critical Chance bump, stamina-scaling damage, and so on), and armor pieces grant stat lines or set-specific bonuses. Ascending a Rare item to Epic adds a second passive effect on top of the first, and the two effects stack. The community data from the launch build groups these passives into three broad buckets: damage (flat damage, Critical Hit, Critical Damage, condition scaling), reload speed or handling (faster reloads on firearms, faster swing recovery on melee), and damage reduction or defensive triggers (flat defense, percentage reduction, conditional self-heals).

Because the pre-ascension passive is preserved, the Tumbaga cost buys compound value. A Musket with a reload-speed roll becomes an Epic Musket with reload speed and Critical Damage; a halberd with a damage-scaling roll becomes an Epic halberd with that scaling plus a second line on top. This compounding is what separates Epic gear from Rare gear in practice: Rare is strong, Epic carries the combined strength of two passives, and the gap typically matters most at the first tough boss where a single unbuffed hit can still kill the character.

Also Found in Ruins Dig Spots

In addition to Blackbeard Treasure Map chests, Tumbaga Ingots appear as a rare drop from the Ruins scattered across the archipelago. These are the same map locations that reward the player with rare crafting materials, lore fragments, and occasional unique gear, and they are reachable well before the player is strong enough to farm Blackbeard fleet encounters for treasure maps. Sweeping every ruins marker inside an island's travel loop is the baseline Tumbaga farm for early-to-mid game players; the drop rate is low enough that most sessions end with zero or one ingot, but the steady trickle over several in-game days does compound.

The combined picture is that Tumbaga supply has two speeds. The slow, steady source is ruins exploration, which works from the first hour of the game and keeps flowing for the entire campaign. The fast, burst source is Blackbeard Treasure Map chests, which usually drop multiple Tumbaga Ingots per chest once the player is strong enough to clear the named encounters that yield maps. Planning the ascension roadmap around both sources (rather than relying on either alone) is the standard community advice for avoiding long Tumbaga-starved stretches.

Saving Tumbaga for Late-Game Gear

Because Tumbaga is scarce, every community build guide repeats the same piece of advice: save Tumbaga Ingots for gear you actually plan to use into the late game. Spending an ingot on a Rare weapon that the player replaces two hours later is a straight loss, since ascension cannot be reversed and the Disassembly Table does not refund Tumbaga even when the rest of the material cost comes back. The safer pattern is to carry a Rare weapon (or armor piece) unascended for several combat encounters first, confirm that the passive matches the playstyle, and only then commit the ingot.

The two practical heuristics most veterans settle on: stockpile three to four Tumbaga before the first ascension so that a single unlucky drop window does not force the spend, and pick ascension targets whose Rare passive already reads as useful at baseline. If the Rare passive is weak on its own, the Epic second passive has to carry the whole item by itself, which rarely justifies the ingot cost. If the Rare passive is already strong, the second passive turns a good weapon into an exceptional one, which is where Tumbaga generates the most value.
