Skills

Storm Atronach: For Single Target fights make sure to use the Atronach as it will give you more dps, group members can also activate a powerful synergy that gives them Major Berserk, applying a 25% damage boost for 8 seconds to themselves and the Atronach.
One Pet: If you prefer one Pet only you can always change one of the pets so you can have Inner light or Bound Armaments on both bars.
Shock Rage: For max AoE damage you can also use the Shock Rage Ultimate.

Skills explanation:

Degeneration: Very strong single target damage over time effect.
Deadric Prey: This ability deals damage on its own and it boosts our summoned monsters damage by 40%, must be up at all times.
Crystal Fragments: Deals a lot of damage and also gives us access to the Exploitation passive to increase our Spell Crit by 6%!
Volatile Familiar: This pet can tank enemies and if you active its ability it activates a strong AoE damage pulse that hits everything in a 5 meter range. And because those pets scale of max magicka, it will deal an insane amount of damage.
Twilight Tormentor: Strong single target damage pet. Activate the skill till 50% of health, then stop using it.
Elemental Rage: This ultimate can also be used on trashpacks, it is the strongest ultimate in the game and deals the most damage in a short period of time.
Unstable Wall of Elements: This ability is an AoE damage effect that covers a huge area in a shock field and also explodes at the end. It also procs off balance which gives us an additional 10% damage due to our Championpoints.
Lightning Flood: Small shock AoE damage effect that deals a good amount of damage. Friendly group members also can active a synergy that deals good damage.
Empowered Ward: This ability is one of the most important ones. It gives you an insanely huge shield that protects you from any incoming damage. That is the reason why Sorcerers usually survive longer then other classes, because they have a huge shield available. Also gives Minor Intellect to you and group members, increasing Magicka Recovery by 10%.
Storm Atronach: Strongest Single Target Ultimate for the Sorc, make sure to keep Daedric Prey on the enemy to benefit from the damage boost.

What about:

Critical Surge: If you play alone you can also use Critical Surge instead of Crystal Fragments, it will help you stay alive because it heals you.

As you see, we have a lot of Damage over Time effects that we need to keep up. That also makes the build so strong, because we have so many Damage over Time effects that hit the enemies, most of them are even AoE Damage over Time effects so it can hit multiple enemies. Because we have a lot of shock abilities we can also proc Concussion a lot, which increases our damage by 8%. Concussion can proc Off Balance from the Blockade of Shock which increases our damage by another 10% due to our Champion Points (81 Points in Thaumaturge, that way we unlock the “Exploiter” Champion Points Perk).

You can replace Hardened Ward with Soul Splitting Trap to gain more dps, but you will lose your shield
