If you are excited about the upcoming GWENT Challenger #2, we have more good news for you - you will be able to gain some in-game rewards while watching the stream!
Thanks to Twitch Drops, after you link your GOG.com account to your Twitch account, every 30 minutes of watching GWENT livestreams on Twitch you will have a chance to receive 50 Meteorite Powder or 3 Card Kegs.
Additionally, for tuning in to the GWENT Challenger you will be able to earn in-game title, card keg and the winner’s favourite card (you can find them featured on Player Profiles on @GWENTMasters!).
