Necrophos Frontline Build

I usually prefer items that help with the push as my core, and rarely bother getting an Aghanim's Scepter unless I am obscenely far ahead.

The +30% duration on respawn could be great, especially late, but I don't think it warrants picking up ahead of Shiva's Guard against a right click heavy team regardless.

personally I just get more armour because its far better than physical hp like a heart does as his heal is fairly small so you get armour. My general build is Bottle-some form of boots usually phase or treads then mech then shivas then AC then bloodstone or aghs.
so basically just fill your inven with armour, your aim as necro is just to be tanky as **** to make teamfights last longer, long fight=happy necro
