You start Palworld 1.0 with only two accessory slots, which limits how many stat-boosting items you can wear at once. Both extra slots come from a single vendor, and paying for them permanently expands your loadout so you can stack things like the Double Jump Boots alongside heat or cold resistance gear.
Quick answer: Bring Dog Coins to a Medal Merchant and buy the Mysterious Accessory Box for 100 Dog Coins, then the Box of Mystery Accessories for 1,000 Dog Coins. Each purchase adds one slot, taking you from two to four.
What each slot costs
The two upgrades are sold separately and priced differently. The first is cheap enough to grab early, while the second is a longer-term goal. Buying both requires 1,100 Dog Coins in total.
| Item | Cost | Result |
|---|---|---|
| Mysterious Accessory Box | 100 Dog Coins | Adds your third slot |
| Box of Mystery Accessories | 1,000 Dog Coins | Adds your fourth slot |
Note: These boxes do not sit in your normal inventory or take up carrying space. Each one increases your equipment slots by one the moment you buy it, so there is nothing extra to activate afterward.
Where to find a Medal Merchant
Medal Merchants are the only vendors that sell the accessory boxes. They wear gold cloaks and have a distinct, unsettling grin, which makes them easy to spot among other traders. One reliable spot is the Medal Merchant at the Marsh Island Church Ruins.
You will know each upgrade worked when a new empty accessory slot appears in your equipment screen and you can drop an item into it right away.
How to farm Dog Coins fast
Dog Coins are the rare currency behind both upgrades, and the 1,000-coin second slot is the real grind. The most efficient source is defeating Mimogs, the treasure-chest Mimics that drop a solid chunk of coins when killed.
- Hunt Mimogs whenever you spot a suspicious treasure chest, since they pay out the most per kill.
- Clear out human camps and groups of enemy humans for coin drops.
- Search Scrap Piles, the large heaps of wood scattered across the world, and loot them by interacting.
- Loot regular chests as you explore.
- Take on the Oil Rig Stronghold for a larger haul.
Grabbing the first slot is quick since 100 Dog Coins adds up fast from early looting. Building toward the second slot takes patience, but with two extra accessories equipped, you can run added weight capacity along with level 4 heat and cold resistance at the same time.
