Please make sure that your Twitch account is linked to your Battlerite account.
You may do so under Options > Account > Link Twitch account.
If the accounts are linked and you still haven't received your items, disconnecting your Twitch account from your Battlerite account, and then linking them again might solve the issue.
You can disconnect your Twitch account from your Battlerite account by going to Twitch.tv > Click on your name in the top right corner > Settings > Connections > Scroll down to "Other Connections", find Battlerite and click Disconnect.
If you are still unable to receive your items, please submit a ticket with the following information:
- Your receipt of payment
- Your Battlerite username
- Date of purchase
