In Palworld 1.0 your character begins with two accessory slots, which is rarely enough once you are juggling climate undershirts, movement boots, and stat pendants. You can permanently raise that ceiling to four, but the upgrade is locked behind a special currency and an out-of-the-way vendor rather than the normal Technology tree.
Quick answer: Collect Dog Coins, travel to a Medal Merchant inside a church ruin, and buy both the Mysterious Accessory Box and the Box of Mystery Accessories. Each one adds a single slot, taking your total to four.
What the accessory boxes do
Two items control the upgrade, and both are one-time purchases. The Mysterious Accessory Box raises your equipment slots by one, and the Box of Mystery Accessories raises them by one more. That is the full extent of the increase. Four is the hard maximum for a single character, so there is nothing else to buy afterward.
Both boxes behave like key items. They never occupy inventory space, similar to Lifmunk Effigies or Pal Gear, and you only need to own one of each for the effect to apply. Once bought, the slot stays unlocked for that character even if you die or relocate your base.
| Item | Effect | Cost |
|---|---|---|
| Mysterious Accessory Box | +1 accessory slot | 50 Dog Coins |
| Box of Mystery Accessories | +1 accessory slot | 300 Dog Coins |
Note: pricing has shifted between updates. Earlier Sakurajima builds charged 100 and 1,000 Dog Coins for the two boxes, so if the vendor lists higher numbers than above, that is the older cost structure and the boxes still function identically.
How to farm Dog Coins
Medal Merchants refuse ordinary gold. They only take Dog Coins, a separate currency you gather out in the world. The fastest reliable source is defeating or catching Mimog, a rare Pal that disguises itself as a treasure chest. A single Mimog hands over roughly 15 to 20 coins, but it bolts the moment you engage it, so aim for a one-shot or a heavy stun before it flees.
Mimog show up on islands such as Sakurajima Island, Twilight Dunes, Bamboo Groves, and Mount Obsidian. Hunting at night helps, since Pals glow in the dark and the pale desert terrain makes the chest shape easier to pick out. A fast flying mount lets you close the gap before it escapes.
Beyond Mimog, several routine activities drop Dog Coins as you explore:
- Digging through Scrap Piles, the broken wood-and-metal heaps scattered along beaches and across the map.
- Clearing enemy human camps and looting the corpses left behind.
- Completing Sakurajima Expeditions.
- Raiding the Oil Rig Stronghold and opening its chests.
- Cracking chests that require Pals with specific work suitabilities.
Butchering Pals never yields Dog Coins, so do not rely on the Disassembly Conveyor for this. Stick to Mimog and Scrap Piles for the steadiest returns.
Where to find a Medal Merchant
Medal Merchants are uncommon NPCs who live inside church ruins. They resemble Black Marketeers but wear yellow robes instead of black. Fast travel to one of the church ruin points and step inside to find them near the central statue.
| Church location | Coordinates |
|---|---|
| Desolate Church | 63, -416 |
| Sea Breeze Archipelago Church | -73, -551 |
| Marsh Island Church Ruins | 399, -276 |
| Forgotten Island Church | -461, -13 |
The merchant does not always spawn on arrival. If the church is empty, travel to a different one on the list or roam near the listed coordinates until the NPC appears.
Buying both boxes
Confirming the upgrade worked
The change is immediate and visible. After buying the first box, the Accessory panel in your inventory shows three slots. After the second, it shows four. If a slot still appears locked with a message asking for an item, you have not yet purchased the matching box, so head back to a Medal Merchant and complete the pair.
With four slots open you can stop swapping gear mid-expedition and instead run a fixed loadout, for example a Multiclimate Undershirt alongside movement and combat accessories, and keep it equipped as you cross the Palpagos Islands.
