Okay, all my negativity aside: Build experts!
Desiderius! I want to go Necro path (Restarted from my Alchemist due to the new patch) with something like an Eldritch Knight build - Think Blackguard from DnD or PF Magus with more necro powers. What do you suggest? Bonus points if its flavorful.
Are you talking actual Necromancy as in Animate Dead, or simply using Necro spells? If its the latter, just go with a regular Conjuration Sorcerer or Wizard, get Expanded Arsenal so your Spell Focus and Spell Specialization feats apply to a second school as well, and play your run of the mill control Wizard while dishing out damage with meta-magicked spells like fireball. Bolstered Magic Missile is insanely broken as it calculates its damage wrong, so if you dont mind playing around with bugged abilities you can cheese any encounter with it (it deals 30-40 damage per missile when its bolstered, instead of simply increasing each missiles damage once).
Cast Repurpose before killing enemies, and in longer dungeons you'll end up with 20+ minions as they last indefinitely until you leave the zone.
