Hero, Necro
Why? lots of mana which we are going to need.
Skills
Shockwave
Unholy Aura
Parasite
Regen innate
Locusts
Skill leveling:
LEvel these skills evenly all game. Generally i stop level parasite and shockwave around level 5-6 then mail level unholy aura as ussually ill be getting the corruption staff soon. IF you are getting outfarmed then obviously youd adjust in that circumstance.
How this works well together.
Shockwave farms very well and its low mana cost allows this hero to support it and parasite during the farming stages of the game. Both of the skills together farm well together because any mobs that you miss with shockwave can be killed with parasite. Parasite and Shockwave both also deal alot of spell damage to your opponent which will rip throguh his ams pots and allow your locusts to get in there and eat his flesh. If the opponent trys to kite then your parasite will eat him while your unholy aura heals you which puts you ahead in the duel. Locusts can also really help you farm along with the pvping aspect.
Items:
This build is mana intensive bu the Intel gain from the necro is very strong so you should be able to support it.
Start off with a glittering tiara and a magic shield. Try to have a crown of ages for the first duel and grab a second magic shield plus pots if you can.
For the first duel try to save locusts for farming, dont use them unless you have to. The parasite shockwave combo combined with your regen should allow you to win the first duel.
Generally after this i grab the setarmor and then a thief's mask, upgrading my crown when i feel i need extra mana. Eventually i grab a corruption staff for the death coil and extra hp.
Counters?
Vortex, ams skill, and mana burns do alot to this build. But none of these hinderyour farming very much. So if all else fails youll have the level advantage, main level unholy aura if you see this and the regen + locusts should help out alot.
