Moving to another biome

Does it cost anything to move your pack to another biome?

Is there a limit on how many times you can move, or how often?

No. Moving to another biome will request you to defeat a certain number of wolves (that depends on how big is your pack) in the biome you want to move. There is a time period of some days to finish the quest (but I din't remember how many days)

You can use GC to bypass the battles and move immediatly, if you want

There is no limit that I know about how many time you can move, but the harder the biome it is, the harder hunting preys will be for your hunters.

Thank you!
