In this Guide, you shall learn how to never lay a hand on your enemy, and instead MAKE OTHERS KILL THEM FOR YOU :D
In this guide you shall use many spells to buff your teammates or force your enemys into killing their comrades, or fleeing outright.
You shall also make use of Robes to get some better Magicka Regen and Cost Reductions.
We shall start with the Basics.
Class : Breton. Bretons Natural Resistance to Magic helps with one of your biggest enemies, Mages. Mages spells can wreck havoc on you, ignoring your armor (From Alteration) Completely, so to counter we will need to Have both passive and activated Magic Resistance, Which can come quite in handy against Fire, Considering they get more powerful the more they hit you, which can very easily stack up into fierce on hit and over time damage, however small amount of time they are on you. Plus if you stack it with Wards, a primary defense of you along with Alteration, you cna really dish out some Defensive Play.
Major Skills : Alteration (Armor Rating) Conjuration (More Followers) Illusion (Buffs for Allys, Debuffs for Enemys) Restoration (Healing yourself and others, Plus Magic Shields)
Lesser Skills : Enchanting (Late Game Rektage) Smithing (Reliable Money Income Later On) Sneak / Pickpocket (Putting Poisons on Enemies while your Companion Distract them.)
Optional Skills : Light Armor (For those who dont want Robes)
And our stat Spread. (50% Magicka / 30% Health / 20% Stamina)
We need Magicka for Spells, Duh, Health for Survivability so we can still take a few hits, and Stamina so we can run around, dodging and weaving as we screw with everyones heads, letting our Followers / Hellspawns ♥♥♥♥ them up.

Now, I'll say this once, and only Once, We only choose forms of Indirect DMG, meaning no Weapons/DMGSpells/Fists, So were gonna be using Spells like Healing, Summoning, and Buffs and Debuffs, So we need to do some questing to get optimal gear.
First is Mages Guild. Do it as SOON AS PHYSICALLY POSSIBLE. This is one of the most important because it gives you the best robes in the game, The Archmages Robes, Giving a spell cost reduction to All Spells, +100% Magicka Regen, and 50 Extra Magicka, This is understandibly amazing Early Game and Late Game. The second is more personal choice, Being a Pacifist, you would obviously see interest in the Bards College, seeing it as a hobby, and as a peaceful faction, Other than these Quests, you just go through the Main Questline... Speaking of Dragons...

Being a Pacifist, you can not use any Direct DMG Shouts, so here are shouts I would recommend.

Dismay : When in battle, you want to conserve Magicka as much as possible, this is pretty much a Free Fear Spell, and sometimes Stronger then it.

Disarm : This lets you lower the enemys offensive capability by removing their melee weapon or bow, usually resulting in easy fights if you have Talos Necklace and Talos Blessing.

Aura Whisper : This lets you play a more sneaky Pacifists, Poisoning your foes or taking their weapons before engaging in combat routine.

Fus Roh Dah : Good Ol' Stagger, And isnt technically direct dmg, so Use all you like!

Slow Time : This lets you slow down Time, Making it so you can conjure up a creature, Buff your allys, and Make all your enemys turn on eachother, maybe even throw up an invisibility spell and sneak away to watch the masacre.
