Well I used a graph function programmed with the formula and MATK as x. To test them, I'll just substitute the value as X and it should come out the same with both of them. can i see the math on this, I haven't calculated but intuitively it doesn't seem right
Ice Spear - 403.6 MATK
Meteor Master: (240 + ((403.6 + 50) * 1.4))) * (1.15) = 1006.296
Ice Master: (240 + (403.6 * 1.4)) * (1.25) = 1006.3
Hailstorm - 481.3 MATK
Meteor Master: (300 + ((481.3 + 50) * 3.2))) * (1.15) = 2300.184
Ice Master: (300 + (481.3 * 3.2)) * (1.25) = 2300.2
As far as I can tell, it is accurate.
