Trying to do a quest and it says I have too many items in my inventory. I don't want to get rid of anything but I don't know if it's possible to increase my inventory?

gold account users have an inventory limit of 250 items, but you don't need to actually keep all your items in your inventory. items you want to get rid of, you can put in your shop; and items you want to hold onto, you can put in your vault or a gallery.

ah thank you! makes sense.. I'll probably just dump whatever I have in my vault haha
