On Blizzard's Dragonflight Season 2 Update Blue Post, they have stated that the Revival Catalyst will be enabled on the week of June 13th (NA) / 14th (EU), as well as some additional information:
When the Revival Catalyst is enabled, all characters will gain a charge. Just like before, spending a charge on one character doesn't influence charges on additional characters. This also means there will no longer be a quest for Revival Catalyst charges — All characters will gain a charge at the beginning of every WoW week.The Catalyst is also being worked on to allow Dragonflight Season 1 to continue being catalyzed for transmog purposes for free. However, this functionality will not be available once the Revival Catalyst is disabled at the end of Season 1. Once the Catalyst returns, you will be able to transform Season 1 pieces for free, no charges required.
Revival CatalystWhen 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.
