Build Introduction
The 
Firewall Sorcerer deals Burning Damage to melt enemies. This build utilizes a “fire and forget” playstyle, casting Firewall to build fatal damage over time before moving on. 
Familiar seeks out enemies to supplement the Firewall Sorcerer with additional Burning Damage from Enhanced Familiar.
Season 7 Update (Patch 2.1.0): The patch update allows damage from Enhanced Familiar to scale up with Skill Ranks of Familiar. The Burning damage from Fire Familiar greatly supplements damage output for early leveling!
Check the Sorcerer Leveling Guide Overview for a comparison of all the starter builds on Icy Veins.
Once your Sorcerer character reaches Level 60, switch to the Endgame Guide for the Firewall Sorcerer to continue this build.
