When the Catalyst opens the week of June 13, all players will receive a charge for every one of their characters. These will function the same as they always have - if your Main spends a few to convert items early in the season, it doesn’t impact your alt (or any alt characters you may make in the future).
Unlike in Shadowlands Season 3, there will be no cost associated beyond the charge spent. No Cosmic Flux, no Dragon Isles Supplies, no Apexis Crystals - if you’ve done the work of obtaining a convertible item, that’s enough.
We’re also working to make it possible for players to convert Season 1 items for transmog purposes. This functionality, however, will be disabled for a few weeks as the Catalyst will be unavailable for a time, starting when Season 1 ends. Our goal is that players who are trying to use Season 1-level gear to get their Season 1 transmog set will only need an appropriate piece to convert. The cost will be free and players would not need to accumulate any kind of charges.
