The seventh Catalyst charge can be obtained this week, but each character can only hold a maximum of 6, so don’t forget to check your alts to see how many charges they have left before completing the weekly quest.
The weekly quest for the seventh Catalyst charge can be picked up at the Great Vault in Valdrakken. If you completed all quests since Revival Catalyst became available on live servers, this should be your seventh charge. However, each character can only hold a maximum of 6 charges, which is why it’s important to check your alts and ensure they aren’t maxed out on charges before completing the weekly quest on your main character.
