Raids can be launched by clan members with the necessary rights for Portal Stones, and can later be joined by other players.
The price of a Raid launch depends on its level. Each Raid lasts 24 hours. You cannot cancel the launch and get back the Portal Stones. All Raids can be launched simultaneously. However, 2 identical Raids cannot be launched simultaneously.
You can obtain the Portal Stones to launch the Raid by completing a special clan task, which can be accessed by the clan daily. The aim is to spend Campaign and/or Valley of Treasures Energy.
One player cannot bring more than 600 Portal Stones to the clan's collection. The clan's Portal Stone limit is 36,000 Stones.
