What do you think is a good core item for eradar? What I usually do with skills is max disruption and curse ASAP and get ult when available. I buy RoB and farm and harass if Im doing good I try to get void then follow up from there either get guinsoo or other int staff for damage. I tried using necronomicon and it works wonder too. easy to build with cheap items. What other items would be good synergy with his skills?
