Thank you for asking! While we are trying to lean more on the survival aspect, we understand that some character abilities will make certain tasks easier and this particular thing wouldn't affect our plans. If it's more fun to play out Law being only able to move smaller amounts of earth due to the frost then we would be happy with that! Essentially, feel free to limit character abilities in a way that enables you to have the most fun with threads and plotting and be mindful of other players' desires to play out a survival setting. If nothing else, we can always blame the Door!
