i have 2 griefs,last wish and death phase blades. Playing as barb with a5 merc. Whats best combination for me? like grief+death for me and grief+lw for merc

Last wish should never be used on anything

Using an a5 merc so I assume pvm, dual grief.

Even still, dual grief.

Go naked and dual grief.

Not to mention a5 merc is bad

Act2 merc > all

i think your forgetting most of these people talking about D2R and that is pure pvm so their gear or merc choices really dont matter at all
i wouldn't even bother giving advice
