You can use this option to get your build for an event in the case that you missed. Note that this only applies to games that have run under the 3.0 rule set, so October 2019 would be the furthest back you could go. Note: April 2020 to July 2021 events were Online and require the use of the Online Buy Back Item instead. As with all Advanced Membership applications, if you buy back a missed game and had the AM at the time, you will get build for all three character slots.
If you wish to buy additional build, you can purchase it separately on the registration page, under the store item “Extra Build”.

This item has no refunds and can not be transferred.
