How to Get the Filthy Loot Sack in Queen's Domain
You can obtain the Filthy Loot Sack by defeating Star Lizards on the Isle of Neasied.
These enemies can drop the sack as treasure, so check their loot after defeating them. The Filthy Loot Sack isn't a guaranteed reward from every encounter, and its exact drop rate isn't confirmed.
If you've already collected one, there's no need to search for a special location or character to activate it. Its purpose becomes clear once you gain access to the game's merchant.
For help finding the merchant and unlocking new items, check out our Queen's Domain Shop Location Guide to learn how to access Umbada's Trading Outpost, earn Ancient Coins, and choose the best items to buy first.
What to Do With the Filthy Loot Sack
The Filthy Loot Sack is a treasure item that can be sold to Umbada for 7 Ancient Coins.
Despite its name, it isn't a bag you need to open to reveal additional equipment. Its confirmed use is as a valuable item that can be exchanged for currency.
I recommend selling it once Umbada's Trading Outpost becomes available, particularly if you're still saving Ancient Coins for your first useful weapon or accessory upgrades.
Treasures work differently from ordinary consumables in the shop. Each individual treasure can be sold only once, and afterward it appears on the shelves behind Umbada.
That also means the sack serves as a small record of something you've discovered and sold during your adventure.
How to Unlock Umbada's Shop in Queen's Domain
If you've found the Filthy Loot Sack but don't know where to sell it, you first need to defeat the Shrine Guardian.
- Progress through the Isle of Neasied until you reach the Shrine Guardian.
- Defeat the boss to obtain the Stone Duck Figurine.
- Visit a Crystal Monument after the fight.
- You'll be transported to Umbada's Trading Outpost, unlocking the merchant.
- Sell the Filthy Loot Sack as treasure to receive 7 Ancient Coins.
After unlocking the shop, you can return through the Shop option at Crystal Monuments.
Umbada sells weapons, accessories, throwing weapon upgrades, and consumables. His inventory also expands as you progress, making Ancient Coins useful throughout the adventure.
Other Loot Sack Types in Queen's Domain
The Filthy Loot Sack isn't the only treasure of its kind. Other Star Lizard variants can drop different sacks, each with its own selling price.
| Loot Sack | Enemy | Sell Value |
|---|---|---|
| Filthy Loot Sack | Star Lizard, Isle of Neasied | 7 Ancient Coins |
| Rancid Loot Sack | Aquatic Star Lizard, Obmuer Temple | 8 Ancient Coins |
| Moldy Loot Sack | Learned Star Lizard, Tower of Knowledge | 9 Ancient Coins |
| Waxy Loot Sack | Grave Star Lizard, Deimpo Mausoleum | 10 Ancient Coins |
The different sacks provide progressively higher selling values, but they share the same general purpose as merchant treasures.
For the Filthy Loot Sack specifically, you only need to defeat Star Lizards on the starting island and take the treasure to Umbada. There's no additional crafting process or hidden unlock required.
If you're still exploring the Isle of Neasied, our Queen's Domain Tips Guide covers early equipment, combat, saving, and other useful mechanics.
