As of StreamLegends 1.13, Broadcasters can give gifts out to their channel every day. There's even a chance of raid loot! Here's how it works.
Broadcasters can go to their configure page and click a button once every 24 hours to send gifts to players in their channel. To get to the configure page:
Click on the StreamLegends link at the bottom of the extension (or go directly your extensions page at twitch.tv/[yourusername]/dashboard/extensions/).
Then click on "Configure"…
…or the gear icon if you went to your Extensions page.
Then click on the "Send Gifts" button in your Configure settings.
Players can then collect the gifts by going to the new building that appears in their Guild tab.
