Hey DeDeorum, thanks for the suggestions! I'm not sure what you mean about the 320ap vs 170ap, the difference in clearing a calamity boss is very much negligible with your own stats. Only up to 10% of your own stats get applied. At best you might save around 10-15 seconds on a 6 minute fight but maybe not. Without gear vs with gear would be around maybe 34seconds I think. Still, in the world of competition it's very important but "better internet" and "better hardware" is not really something that PA should really need to worry about. There's no true fair fight but they can at least remove the RNG to make it similar enough.

As for crystals, they are cheap and available for most of everyone and you should mainly focus on having your base skills up to max like critical and movement speed) and the rest is all into HP. Kydicts crystals are good to use as well. You can beat calamity 7 with crappy gear because it won't make much of a difference in the end, but it will help you save a few seconds which could mean the difference between first place and 4th. Orbs and HP crystals are the most important things for calamities.
