1) Do stats scale linearly?
Eg. my base character has an ATK of 1000. Then my equipment set gives 200. Can I say that the equipped character is dishing 20% more damage than the naked character?
2) What does MAG do?
3) Has any of your guys used Kristoph (Invoker)? He is on my main team only because I only have five 4-5stars right now, but his damage is inexplicably abysmal.
4) I have been farming equipment to complete sets (for Kristoph again, his damage really stinks). Is drop rate pure RNG? I assume that higher rarities have lower drop rates, but any other factors behind?
