Build Overview

This build uses Firewall, which has strong Damage over Time. Using Firewall: Ring of Fire, we are applying strong DoT damage from all of our Pyromancy skills, as long as we remain within the ring. Beru of the Threefold Set will automatically cast all Mastery skills, and we use Chain Lightning to expel more damage. In the end, this build will not feel very Firewall-y, but, we will lose all damage if we leave the ring.

This is the T1 starter version of this build. I recommend starting here and taking a peek at unique only so you know what to look for, but start here to get started in Torment and start collecting Paragon levels.

Talisman Priority

Using a 2pc threefold + 3pc cauldron makes your character have explosive shock damage while standing in the ring of fire. Using your skills will proc the Threefold set, and cast more skills. There is a cooldown on these.

If you do not wish to go this route you can opt to use the 5pc cauldron set. Just note the 5pc cauldron sometimes can be bugged!

This is really just preference :)

I honestly don't what to do anymore I have made it to 243 and my build seems to have gone backwards Used to be able to do T12 now I'm struggling in T11 and it seems like the creator of the page no longer responds to messages

BrightRobot•6d ago

What do you mean with you dont have to cast aynthing? Threefold needs you to specifivally cast every element t get a new procc. so you only cast teleport and procc the set every 6 sec? what? Sorry but it seems you left out some important synergy here tbh

RustyStorm•6d ago

What should I spend the remaining Paragon points on? in the red squares around glyphs or just push the yellow and blue ones?

Axus•7d ago

Do you have by any chance or anyone, recommendations for the war plans choices?

Have you ever try zan+Mot? Due the constantly use of Inferno.

RustyFlower•9d ago

Once we move on to the mythic end build for the Ring of Jordan Aspect shouldn't we want yet fire resistance just maxed out and put Rubies on our necklace and both our rings giving us more fire resistance But then the Ring of Jordan would balance everything with that fire resistance and then on top of that we get additional fire damage bonus?

BrightRobot•9d ago

Whats the Chain Lightning for? Its not pyro so its not proccing anything I can see (sadly you are also not mentioning what its for)

RustyStorm•6d ago

The passive gives you 25% of lucky hit for firewall and meteor enchantments
