Hi, Iv always Liked The Darker Heavy/Magical Character's in RPG'S sutch as The Dark Knight, Death Knight, and Shadow Knight's of other genre's.
So i decided when i Bought skyrim to Make the following, Please discuss and help me Perfect my "Vision" with anything helpfull!

Race: Orc
Skill Plan In order:
2-handed
Conjuration
Smithing
Heavy Armor
enchanting
Restoration
alchemy
"Total of 71 Point's to Finish Concept."

Play-style sought after:
Very Tough and dangerous Heavy Melee mix'd with conjured Minion's. Conjured Bow For Ranged.

Fight Sequence:
Target Aquired
Range "Fire astronaut" "Conjured Bow"
Melee "Frost Astronaut" "Higher lvl's will switch to Daedra armor wearing creatures" "2-handed of Choice"

Alternation-Fill in's "When needed"
Restoration-Fill ins "When Needed"

Pretty mutch summon Allies, and view the situation before engaging Choose between range/melee Conjuration's and weapon's and Hit them hard, With duel casting we will be summon 2 astronach's/daedra at later game. Making for a VERY hard hitting and Powerfull, "What i like to call a Void Knight"

Bumb

Just a thought you dont have to take every perk in a tree nd the skill ups still increase damage lower cast cost and increase armor rating. Looks like a very fun build though and im pretty shure you will only need a single familliar-atronach-deadra as you will be hitting like a truck anyway

Currently doing a version of void knight as well heh pretty similar in build

Heavy Armour
Smithing
Restoration
Conjuration
Block
1 Handed

Thought about enchanting but honestly havnt needed to head down that path and very little use for Alchemy since Restoration provides for all my stamina and health increases and Magika dosnt drop after the initial summonings.

currently using Daedra Lord and Fire as my summonings depending on situation rarely use ranged weapons myself but if I need to lure an enemy to a spot will use a conjured bow.

Its a satisfying build you can handle most situations though master conjurers can be a pain when they take control of your lower lvl summonings but that is a rare occurance and since ive put on a few lvls since last encountering one its even rarer to happen.

Good luck with your build
