since i quit cha ill just put out the build i used most, never lost with it =]
hero: battlemage:
skills: tentacles, slow ward or stun field, rejuvenation or consume it doesnt matter u ca get any skills for that one, and death orb
you level tentacles the most out of all of them, since i dont really use the third skill i jus level tentacles to the max first then i level slow ward or stun field when ever i can if i cant level tents.... always level your ulti it can cost u a duel...
and theres my build so if u loose dont blame the build blame your skills k? =] or its either your item build.. my item build owns but ill let u figure out your own item build for a challenge
if u have any questions or need help cuz u cant find a item build, then just whisper me or somthing my name on warcraft is smackmyhoe
