Supercell has published the Cosmic Curse: Portal Panic calendar for October. It highlights temporary troops, a Portal Challenge, and a medal event from October 8th to October 25th.
The Medal Event is listed as accessible from Town Hall 6, and the trade shop is open until October 27th. Therefore, the completion of the collection and the last day of spending medals are different dates. The Portal Challenge is scheduled for October 6–13 and allows you to try out new equipment and temporary troops. Do not transfer the conditions of one event to the whole season: the thresholds of the town hall and the dates are different. Check your current client for exact rewards and availability. Plan your participation around the tasks available now, rather than a list of events that have already ended.
