Very carefully tested madstone boots frame by frame.
They are 9-10% haste. No longer 20% per description (nerf happened back in update5)
I informed flimsey firewood and madfloyd about this problem in tells on lamania and they were unaware of the issue but said they would look into it.
Your OP is a bit confusing as you call your haste boost row "enh bonus"
But the haste spell itself is an enhancement bonus, yet you list it ina colum. that really confused me for a while.
Should renamed it "action boost bonus"
As its for just haste boost right, which are typed as "action" bonus to attack speed.
