To the dude talking in his silly lingo, I'm assuming some kind of dork-*** dwarf, he should remember that in a duel with a necro simply dispatching his "minion" does not equal certain trumph.
He can just shadow step... Dot you... Run...
Hopefully for you his MR is low so you can Stun / Root / Blind
Your best hope for killing a necro is skills or being a wizard
