If you’ve linked your accounts but still haven’t received rewards, please check the following:
1) Make sure that you linked your Twitch account where you watched the live stream with the Steam account where you’ll be playing The First Descendant.
2) Make sure your linked Steam account has The First Descendant in the Steam Library.
3) Make sure you clicked “Claim Now” in Twitch Drops Inventory.
4) Make sure you watched Drops live stream in The First Descendant category.
5) Make sure you met all the requirements. You can check your progress in your [Twitch Drops Inventory]
6) Make sure you are watching streams with drops enabled.
Streams with drops enabled show a notification about drops on top of the chat box once you enter the stream.
Some streamers add the “drops enabled” tag to their streams even if they haven’t really enabled drops, so please double check
*NOTE: There may be a delay in the Twitch Drops reward delivery.
The rewards will be sent within 24 hours to your in-game mailbox.
Please check the notice for more details on how to link accounts and The First Descendant streams.
