We've just released the Sanctum Mystery Box, which follows the same model as the Kalandra and Sentinel Mystery Box, with no duplicate microtransactions! Each of the microtransactions in this mystery box has visual behaviour that interacts with your gameplay.
There are 14 microtransactions that you can find in the Sanctum 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!
Because of the lack of duplicates, each box you open implicitly increases the chance of opening the remaining microtransactions you haven't received yet.
Receive a random prize with a Sanctum theme! It'll appear inside your MTX stash, waiting to be unwrapped.

Contains five Sanctum Mystery Boxes, each containing a random prize with a Sanctum Theme.

Distribution
The chances of getting one of the distinct microtransaction types is 1/14. However, the chance of getting a specific thematic variation of those microtransactions varies and is listed above, next to each variation.
Note that these chances only apply to the first box you open. Every subsequent box you open increases your chances for the other microtransactions, due to the lack of duplicates.
How to open your Mystery Boxes
After purchasing your Sanctum Mystery Box, you can find it in the Consumable section of your microtransaction stash in-game waiting to be unwrapped.
Note that these Mystery Boxes have random outcomes. Some items are rarer than others (as listed above). You are guaranteed to get an item that is worth at least what you paid for it (50 points) and it's statistically more likely that you'll receive something of higher value.
Receive a random prize with a Sanctum theme! It'll appear inside your MTX stash, waiting to be unwrapped.

Contains five Sanctum Mystery Boxes, each containing a random prize with a Sanctum Theme.

Once you've received a reward from a mystery box, it's possible to purchase extra copies of it in the store for the same price as the mystery box. These microtransactions will be available outside of mystery boxes when they enter the store one month after the league ends.
