Inventory slots in Gw2 are a key part of the game, and they’re important for a couple of reasons. First, they’re necessary in order to hold more items in your inventory so that you can better outfit your character and complete quests.
Second, inventory slots are important for farming resources, as they’re the only way to collect specific items that are needed for crafting.
The best way to increase your inventory slots is by leveling up your character. This will increase your overall stats, which will in turn give you more inventory slots.
Additionally, you can purchase inventory slots from merchants or other characters in the game.
