+ + + = ggI think everybody knows that you should cast Ancestral Spirit and STUN and ULTI then dont touch your enemy until ulti becomes activated. I thought what can we do during waiting and after ulti? Then used necronomicon in one game. Result was perfect.
After casting your skills open necronomicon and get ready for hitting. These necro dudes have great mana burn and true sight. You dont need dust or gem etc. Also they have 60+90 dmg with attack speed and movement speed aura. (level 3) It is like there is one more hero with 150 dmg.
Another issue is Tauren Chief need some strenght and mana capacity. Necro gives:
+15/21/24 Intelligence
+6/10/14 Strength
Level 1 Necro is 2700 gold. They seem like good match.
