I believe there are several rune to be added not just 'lich' rune
But if your looking for something right now: this is a nice to have
"Demonic" (unholy) +15% body/nature/physical/summoning/basic complexity.
instead of lich stats which is:
"Lich" (undead)+14% mind/physic/summon/enchant/sensory/blood/basic complexity. And +9% body/divine/nature/defensive complexity.
If you want a lot of resisted go "Lycanthrope". I noticed demonic have 15% in body not 9% and for physical i rather have 15% instead of 14%. Do the math when you get to e1000 and a gain 1 in all complexities each 30 epic
