This build takes advantage of your Firewall to deal burning damage while utilizing all of your Defensive Skills for mobility and to build Barriers for survivability. You will constantly have Barriers because of your Ice Armor, Flame Shield, Passives (Protection, Icy Veil, and Warmth), and the unique effect of Temerity. This will help you stay alive as long as you are hitting enemies and damaging them with your Firewall.

Crippling Flames can help you Immobilize enemies to easily kite them with your high Movement Speed from Affixes and Enhanced Flame Shield. On top of that, you can also use your Frost Nova to Freeze enemies and apply Vulnerable status to further increase your damage output.`

Enchantment Slots

Firewall Warmth Enchantment Slots
Firewall (Level 15)	Flame Shield (Level 30)

Your main source of damage will be your Firewall skill. Since you will be spamming this ability with your high Lucky Hit Chance, you can trigger its Enchantment Effect constantly to get free casts of Firewall and spread it on a large area. Build up your damage over time to maximize this build, and you will easily kill groups of enemies.

Because of the Flame Shield Enchantment, you can play aggressively without worrying about taking fatal damage since it can automatically trigger to save you from dying every 2 minutes.

Firewall Warmth Playstyle

Firewall Warmth Build Tips
Recommended Openers and Rotations Continuously Spam Your Firewall Barriers and Heals Will Keep You Alive Use Frost Nova to Apply Vulnerable

Recommended Openers and Rotations

Trash Mob Opener and Skill Rotation

With your high Lucky Hit Chance, you can trigger your Firewall Enchantment and spread free Firewall in the area. This will allow your Combustion Key Passive to activate and it will burn down enemies instantly.

Boss Opener

Since your main source of damage is a DOT effect, you will not be able to burst down the boss. Instead, you need to continuously kite the boss while spamming your Barriers and Firewall during the fight.

Continuously Spam Your Firewall

On this build, Firewall is the only skill that spends Mana. Try to spam your Firewall as much as possible to trigger its Enchantment Effect. Most of the enemies will die from your Firewall before you run out of Mana.

Barriers and Heals Will Keep You Alive

Since most of your Defensive Skills provide a free Barrier, you will be able to survive most enemy attacks if used correctly. With this, you can play aggressively and dive into enemies without worrying about your health.

Warmth and Temerity

Warmth will allow you to heal as long as there is a nearby burning enemy. Because of this, the unique effect of your Temerity will grant you free Barriers if you keep spamming your Firewall.

Use Frost Nova to Apply Vulnerable

Frost Nova Freezes all nearby enemies and it also applies a Vulnerable status. Use this to your advantage to deal more damage with your Firewall to clear large groups.
