If I use a krono a week into the month it will last 30 days correct? So last a week into the next month is what I mean.
Yep. It just adds 30 days to your current all access time, so if you x days of all access and click a krono you'll now have x + 30 days of all access.
Krono's also come with 500 SC however, if you use lets say 2 krono's get 60 days..You have to wait 30 days before you can claim the other 500 SC..So you'll get it from the first one, then have to wait until the dwindles down before you can claim the next 30 days worth of SC..I'm not sure why they did this but they did, just thought I'd give you a head up before you consumed like 3 and figured you'd be getting 1500 SC SC= Day break cash.
