How would I make one?

Use conjuration you can reanimate things to fight for you.. well thats a start anyway... chicken companions are pointless though

Slap a fire rune onto that re-animated chicken, and blammo instant success.

what skills should I use

meh.. i got a bounty for punching a chicken, so i decided he would be a worthwhile zombie... then i decided to punch the chicken again... dont like chickens

anyways

well only having played a little bit of it... i have a novice spell called "summon zombie" or something... aim it at a dead guy and blamo he's up and fighting for you... for a little while
