Test the blade of heroes
Fury of the thunder hit my golden shield!
So we'll fight against the wind for the glory of the kings

And we'll ride with our lord for the power and the thrown
in the name of Holy Thunderforce!

Yes, the fire damage is already calculated into the 29.1 DPS. ((39+5)+(74+10)) / 2 = the average damage per swing = 64 damage 64 / 2.2 = 29.090909... rounded to 29.1
