You should include a explanation of how to get a teleportis shard in the guide and could you please tell me I do not know and want to switch kingdoms.
If your castle is over level 5 you cant migrate. You have to wait untill kingdoms protection period is over. K1 protection period is 52 days at the moment. If the kingdom is new, its longer, for example K7 protection period is 86 days.
When Kingdom 1 protection period is over, I believe that then we see migration packs in the store.
