Yes, depending on the level of the scroll that you have, whether it is easy, medium, master, or another, you will need a corresponding stash level to store the items. The different stash unit levels are required to store the items needed for each scroll, and they need different resources to be built effectively. The level of the stash you are building does matter, as higher-level stash chests will be able to hold higher-level items. Plus, with the higher-level stashes created, you don’t need to drag all your items around from place to place, especially if combat is required to continue with the quest. No one wants to die and then have to go and get their items back!
