As the title suggests, this guide does not take into account SHC or miscellaneous one-time sources like main story progression, battle rewards, events, achievements, memory leveling, etc. For P2P, it assumes a consistent renewal of the Aurum Pass each month and both Aurum Gift Packs each week for a year. In both the case of F2P and P2P, it assumes a consistent completion of daily and weekly tasks and check-ins.

Why no SHC? I wanted to see the baseline on how many diamonds players can realistically earn monthly and annually by only doing/paying for the absolute bare minimum. In addition to that, SHC can be unreliable for early-mid game players who lack good companions/protocores and the amount earned can vary a lot depending on your particular builds. To keep it simple, I'm ruling it out. Just note that if you can manage to 33/36 SHC every cycle consistently, you can earn an additional maximum of 15,840 diamonds/105 pulls per year as F2P and P2P from this method alone.

To be as conservative as possible, I won't be including the 10 + 10 free Deepspace wishes we typically get with new banners/events. Reruns don't offer them either, anyway, so it's best to overestimate how many diamonds you'll need than the other way around.

As for the reason I've made this guide, I can never find one that itemizes everything so you know precisely how the math is mathing. And math is fun. I am employed, I promise.
