This is a MINIMUM build (and it's how I play my sorc), you can grab all the weapons and class passives if/once you have more skill points. I put some utility passives from Dark Brotherhood, Vampire and Assault but those are just suggestions (they really help moving around)

This skill bar is for when you WONT chug Essence of Spell Power potions. You can use a regular Essence of Magicka potion if needed and still benefit from Maj Sav/Brut. That being said, the rest is pretty much copied from Alcast's build https://alcasthq.com/eso-magicka-sorcerer-build-pve/

You can get the rest of the CP there. The food is Witchmother's Potent Brew, nice and cheap.

Try and keep everything up and use Force Pulse as your spammable and replace it with Crystal Frags when it procs. Your ult is Atronach (you can grab the other morph for more AoE), the other being frontbar'd only for the mage's guild passive.

WHEN YOU FARM THE MEDUSA SET: you can finally drop Channeled Acceleration and slot the Undaunted Mystic Orb or other skill of your preference (Elemental Drain if no one in your group is running it)

Good sets to use until farming False God's (trial) and Medusa (dungeon) are:

Juliano's (craft)
Mother's Sorrow (overland)
Burning Spellweave (dungeon)

For single target:
Siroria (trial) (just dont pair it with false god's)
Spell Strategist (pvp)

About the monster sets, you can choose many, Zaan being just one of the possibilities (the crit bonus is nice):
Ilambris
Valkyn Skoria
Iceheart (if you are dying too much)
Slimecraw (if you are not getting the buff from Combat Prayer)


Remember, you can pair any of those sets and be just as fine. The advantage of Medusa is you can drop Channeled Acceleration which is boring to use. The bad thing is it can only be used as frontbar (jewels+staff), as it is heavy armor. If your traits/enchants aren't perfect yet, there is no problem too. You can work there. The most important is to always LIGHT ATTACK WEAVE, manage your resources, learn the dungeon/trial mechanics and try to stay as still as possible so your healer can buff you.
