On my Battle Mage I have a Legendary Dragon staff, it has like 156 Magic ATT, but also has 9% Critical Rate and 20% Boss Damage.
In the free market at the moment there is a Elemental Staff with 187 Magic ATT, and 9% INT potential for 900m.
It's kinda pre-scrolled with +2, 4 slots remaining.
Would that elemental staff be a good investment? keeping in mind the Battle Mage attack speed thingy
