A two sockets manticore will gives me little damage upgrade (like 15% at best) for an astronomic sum of gold. Belt, ring and helm upgrade would be cheaper and grant me higher DPS boost.
I paid my manticore 8mils and I get better DPS than 200m manticore 2 sockets. I think I need 1 billion to get that 15-16% damage upgrade.
I used asian calculator to compare DPS. I didn't compare with a ruby instead of an emerald so the second socket only grants me +100% CD.
Would a calamity be a better choice? I see a lot of 1700DPS calamity being used on high mp DH.
