Found on your map, you will need to upgrade your Fortress to Level 3 to unlock Red God’s Altar.
The Red God’s Altar is where you can tap “Give Tribute” to spin the Reward Wheel and win a random reward.
Rewards include:
- Food
- Silver
- Iron
- Time Speed Ups
- Melisandre Shards
Every spin will consume 1 R’hllor’s Boon. The top right corner of the screen shows you how many Boons you currently have. You will be able to spin for free once every 18 hours.
Note: The available rewards change each time the refresh timer expires.
