The secret to increasing the amount of item slots is hidden in a single card: the Arsenal. This card can be stacked, if you’re lucky to find more than one in a single loop. This allows you to increase your item slots by more than just one, although that happens extremely rarely.
How to Get More Item Slots in Loop Hero
In order to unlock the Arsenal card you must have two buildings: Smelter and Intel Center. But first you need to craft a Smithy, which requires a campfire available at the start of the game.
The Smithy can be crafted using the following resources:
2 Stable Wood 4 Preserved Rock 7 Stable Metal 2 Food Supply
When the Smithy is ready, you can start building the Herbalist’s Hut:
2 Stable Wood 3 Preserved Rock 4 Food Supply
After the Herbalist’s Hut build the Field Kitchen at the campfire using:
3 Stable Wood 2 Preserved Rock 1 Food Supply
When the Herbalist’s Hut and the Field Kitchen are ready, build the Gymnasium:
5 Stable Wood 3 Preserved Rock 6 Stable Metal 1 Metamorphosis
Once you have both the Gymnasium and the Smithy, you can build the Supply Depot:
9 Stable Wood 17 Stable Metal 9 Food Supply 3 Metamorphosis
After the Supply Depot you can start building the Intel Center using:
12 Stable Wood 15 Stable Metal 17 Food Supply 3 Metamorphosis
Finally, you need to build the Smelter using this recipe:
5 Preserved Rock 18 Stable Metal 3 Food Supply 1 Metamorphosis
Once the Smelter and the Intel Center are done, the Smelter unlocks Arsenal and Temple Storm cards, as well as additional 30 points to your base HP.
The Arsenal card unlocks an additional item slot for each of the three hero classes:
Warrior gets the extra slot for Helmet Rogue geta the extra slot for Amulet Necromancer gets the extra slot for Shield
Arsenal cards can also drop randomly from the chests. In that case you can stack them and have another extra slot for one of your heroes.
