Ultimate Ironman Mode is where players are completely self-sufficient and are not able to use banks (or depositboxes).

The main challenge of this game mode, is that you're completely unable to use the bank or Grand Exchange. This means that you're limited to the 28 inventory spots and some other small storage instances. This game mode requires you to be able to plan ahead.

This guide will mostly focus on the different types of storage that are available aside from just your inventory:

The refund box can be accessed by talking to the Refund box keeper at Varrock or Edgeville.

The refund box is going to be one of the best storage locations. The refund box will store a wide variety of items, mostly being untradeable. Some items can be reclaimed for free, others for a fee. So keep this in mind when trying to deposit items into your refund box.

The way a player 'deposits' an item into the refund box, is by dropping it and waiting for it to despawn. Other players won't be able to pick up untradeable items, but watch out either way. Also, be a 100% sure that the items go to your refund box. If they don't, they will simply vanish and be lost forever.

Below is a list of items that can be stored in your refund box:
