So, I've been playing on skyblock with my friend for about two weeks now, and we heard about "seasons" and how they end you lose everything, does this mean if I buy keys off the store then I lose whatever I get anyway?
Not necessarily. At the end of every season, donators get the /resetvault perk, which allows you to fill up to 9 slots with Seasonal accessible objects, such as armor, weapons, etc. Physical objects that have not been duplicated and can be used in the next season.
Along with that, you also get to keep whatever perks you earn throughout the game, such as titles, chat colors, etc. Things that are not quite physical but are perks that you have won and can use.
Of course, most things
don't transfer, and that's a bit saddening, but it's also a very nice way to refresh the game and give everyone a chance, while also making it fun and not so ridiculously repetitive, you know? I think it's a nice system that gives just about everyone a chance, and gives you a deadline to work against if you have something specific you want to do. Almost like a life!
