How much does orb do compared to individual shards

[Ares]

It's hard to say. Orb works in mysterious ways.

It's quite difficult to put a damage value on Orb, what with all the shards in addition to the -resists that mastery provides. Most people believe that a completely leveled with +full gear and skillers can do up to 4k on a direct hit.

you can figure it out it all takes some math.. how many shards are there in a orb? my old orber did 1.1k around there plus mastery and the number of shards hit... so yeah just do math
