Skill Points
49 to health. Use armor glyphs to tweak your Magicka and Stamina Ratios.

Leveling
This build is not born, it's refined. Start off with your sorcerer lines. Mix your armor for versatility later (I went 5 heavy, 2 Light). Sanguin Alter (Undaunted) can be a help. Degeneration (Mages Guild - Entropy) will be a big deal so get those lorebooks and morph it fast. A pet makes levelling easier. Later you won't want one, but Hardened Ward can be an tanks friend for the open spell slot so consider levelling Daedric Summoning. Resto staff is suggested because Mutagen leveling will give you the healing bump you're missing early on but if you know that you don't want to support then dual wield for the self heal morph or destruction staff for leveling DPS won't hurt.
Around level 20-25 if you've been keeping up with your skyshards and lorebooks you will start to come into your own. Then the fun begins.

Strategy
You get 5 spells and an ultimate. 1 of those spells is and open slot. I prefer Endless fury (range pull/dps burn) and Hardened Ward, but Sanguin Alter can be a big support ability in boss fights. You'll see what I mean in a minute, but tanking mobs is about Thundering presence + Degeneration. Keep Thundering up at all times unless mobs are stunned or using an ability that only requires range dodging. So throw Thundering, run in and hit 2-3 mobs with degeneration for your heals and start taunting.
Taunts keep aggro in ESO, period. Proximity + DoT help your hate but they won't keep it on pull so Taunt fast or throw and endless fury. Eventually you will get your Undaunted taunt, Inner Fire/Beast, and life becomes easier when you need group aggro if you want to waste a slot for it.
Refresh and reapply these often. High defense, passive damage from AoE and dots, and self heals

Restoration - Siphon + Power Surge
Dual Wield - Blood Craze (get moar health)

Magicka Recovery
The heavy armor and 1H detracts from magicka regen. I keep a 5/2 Heavy to light armor ratio most of the time (you won't miss it) giving some of the passive regen from the light line. Reduction Jewelry and regen food are nice. Set items rock. The Warlock set early on help (I kept mine way past lvl 16). Degeneration is cheap and Thundering presence is the only other requirement. Power Surge (after morph of course) is efficient, even if expensive, damage. Pace it out and switch on your ultimate if needed.
Ultimate
Energy Overload is great. Switch on and off at will and it's free magicka. Throw a taunt and then you have 15 sec to light attack for +magicka until you need another taunt. If you don't have the mages guild taunt loaded then you will need to switch off for a ransack taunt, but by then you should have another 100-150 magicka from this ultimate.
Absorption field gives you group dispel/heal support. This is my set 2 ultimate.
