Not pleased with the format, but I'd revise mine to something like that to take into account the giga juice one:
(Magic*1.1*(3[*Mastery] + Magic*0.00306[*K])+INT/2)*Spell/100
Likely K being around 0.8-0.9 (all items in [] are minimum damage again)
(Magic*1.1*(3[*Mastery] + Magic*0.00306[*K])+INT/2)*Spell/100
Likely K being around 0.8-0.9 (all items in [] are minimum damage again)
