We've just released the Necropolis Mystery Box, a new mystery box without duplicate microtransactions! Each of the microtransactions in this mystery box has visual behaviour that interacts with your gameplay. Check out the contents of the box in the video below!
There are 22 microtransactions that you can find in the Necropolis Mystery Box. Each of these microtransactions has a varying number of thematic variations, and you'll never receive a duplicate copy of a variation that you have already opened. For example, if you open one variant of a microtransaction, you may later receive another variant, but you'll never get a duplicate! Check out the full details at pathofexile.com/mystery-box
