There is no Catalyst charge catch-up in Dragonflight. If you haven’t completed last week’s Catalyst quest, you will be only granted 1 charge this week upon completing the weekly.
Many players wondered if they could catch up on Catalyst charges when they did not complete last week’s Catalyst quest. Unfortunately, the answer here is no.
Completing the weekly quest will only grant you 1 Catalyst charge this week. However, the good news is all your alts will be given a charge when you complete the weekly quest on your main and all characters on your account can contribute to the weekly quest progress. Every character can accumulate a maximum of 6 charges.
This week, you can pick up the weekly Catalyst quest conveniently at the Great Vault in Valdrakken.
