Man they're going crazy with these vector abilities. Gauntlet seems like a pretty cool guy (eh masturbates all day and doesn't afraid of anything), but I haven't really played enough games with him in it figure out how to actually use him. He seems pretty similar to Devourer, but he doesn't build like Devourer since he doesn't get hurt by his slow, so Headdress is no longer a core item.
I also played Balphagore for the first time today (zomg so fun) and had a similar problem figuring out a build for him. Definitely a super-pusher, so I figured aura items would be good on him. Nome's seems like a no-brainer -- improves the longevity of his minions, and the INT and mana regen really help with his weak mana pool. Puzzlebox also helps in that regard and gives you a nice haste aura, but I'm just too much of a noob to actually micro the critters. But yeah, after that, I have no idea. I guess you could stack armor so you can stick around as long as possible and get the 80+ charges before ulting. I could also see Portal Key to get you in silence/vomiting range. What say you guys?
