how do you deal with magic immunity?

I'm having a hard time killing magic immune monster (unless there's a crapload of body nearby)

Do you have any tips for my bone necro|||amp + merc with any of the generic runewords or even elite uniques should kill em pretty fast. Given as how mercs are a large part of killing speed of bone necs anyway, this shouldnt be much different|||Most magic immunes are Greater Mummies, anyway, and they always spawn with said crapload of bodies nearby.|||Are there any spells/items that reduce magic immunity by a % anymore? I know that Lower Resist used to, but they nerfed it...|||Well first amp will help out a lot and you only need 1 point into that. Spear the ones that are not immune and ce many corpses when there is. If not let merc kill amped magic immune.|||Yeah and the merc should really be doing around 10 times more DPS than the necro himself(on a single target that is) so it really helps to get his gear up and leverage off his high potential.
