PC on heavy plagueborn maul of enchanting

Hi all. thanks in advance for any help u can give me

the stats are

heavy plagueborn maul of enchanting

Blunt dmg 14-23 (req8 hammer)

dmg +15% (always)
armor -10(while attacking)
lengthens weakness on foes by 33%
enchantments last 20% longer

I know it's not max dmg so that will drop the price..
but it is +15% dmg always.
and the 20% enchantment is good..

so how much do you think it is worth?

thanks
