take Crushing Blow MS off of Bracer and put +100% Blistering on.
change Focus Talent to Sorcery Talent on Chest.
change Wizardry Talent to Amplify Talent on Head.
change Reclaim Talent to Fester Talent on Amulet.
on the Pet, have a +50% Bleed Damage and +15% Immolate (to make up for losing Wizardry Talent).
why???
the extra Blistering gives +200% Bleed damage total, and the +50% Bleed Damage improves Bleed Damage to +300% total.
Sorcery increases Fire DoT damage, which means Immolate causes more damage which means Bleed from Blistering does more damage. although you lose +50% weapon damage, you gain +100% Fire DoT damage.
Amplify 20 gives +40% damage when an enemy has a DoT on it (this means Fire DoT with your build). with this and Sorcery, your damage, Fire DoT, and Bleed damage should be higher.
Fester gives increase your Fire DoT to 3 seconds and speeds up the Fire DoT to 1.5 tics a second, so in 3 seconds you do 4.5 Fire DoT, and each Fire DoT is doing double damage from Sorcery…
when you get them, you can use Obsidian Crystal to improve Crystal affix values.
one thing that is really hurting your build is it’s need for at least one +100% Fire ED. (can’t be rolled with Ruby, you need to find an item with it) this will really increase your damage a lot. two +100% Fire ED would be best.
also, you should have your Power Stat at 60 or higher.
hope this helps.
