Do leftover keys at the end of a season get transferred to the next season? This would mean that in some cases it might be better not to waste keys especially if you think your position will not change.

Or is it always the best option to use up all keys in a season?

Is it also the best option to try to use up all charges of darkness in a season or to save them for certain occasions?
