You get Summon mana 1-2-3 at Keep level 3 from Altar of Shadows.

My undead necro is currently level 47 and have 1 mana/sec regen by default, 2 if he buffs himself with Enervate.(not to forget the Mana Flow which makes spells cost less)

Altough he have to avoid combat(due to the fact that he has 42 Health) he casts level 4 necromancy spells, filling mines from 16 mana(4 zombies raised from raise Zombie without Black Portal), and raising hordes from 24 (level 4-5 skeletons)

Enemy Summons have a chane to join my side(Arcan Magic again), and I summon Doom Knights/Liches/Vampires kinda often.

Alchemist is a better combo with the Dark Dwarves.
