Platinum Staff - Platinum Long Bow - Plagueborn Maul

Hi guys,
can you give me a pc on the following items?

Platinum staff
max dmg - r.13 (energy storage) - inscription slot

Platinum bow
14-28 - r.10 - inscription slot

Plagueborn maul
max dmg - r.9 - +14^50% - lenghtens by 33% weakness - +30hp - no inscription slot.

Thanks in advance!

Edit : about item #3, how much is worth a +30hp mod for hammer?

1. 3-5k

2. not max, sell to merchant

3. salvage the 30hp


30hp for hammer is about 5k
