You can ask other players to help boost the rooms in your Keep and do the same for them. Each room that can be boosted by your Nobles can also be boosted by a visitor. Nobles from other families give the biggest boosts! To send a Noble to a friend and help them boost a room:
- Tap on their city
- Tap "Keep" to view their Keep
- Tap on your ''Family'' button
- Pick the Noble(s) you wish to bring over and tap "Summon"
- Once your Noble has reached the Keep, drag & drop them to a room of your choice
TIP: Work with Alliance members to help in each other's Keeps to maximize your rooms boost potential.
