Firewall - This is Fine

Firewall is a Burn build that deals damage over time. It cannot critically strike, but it sure can roast a MF. This is probably the first season where PURE Firewall might approach A/S tier due to an insane amount of power from the Seasonal Theme. The theme is essentially, yo lets give Core skills 20x damage on sorc and make them unkillable with 10,000 mana. Yo thanks chief, Good looks. Bless up.

1) Cast Firebolt 3 times every 5 seconds for 60% dmg from explosive combinations
2) Cast Blizzard at least every 8 seconds for mana regen. Also used to freeze packs.

The rest of the loop is very simple
3) Spam Firewall on enemies, let the KRY rune suck them onto you.
4) Evade around for movement, and to create crackling for Convulsions
5) Cast Inferno whenever it is off cooldown on enemies to group them
6) Press Ice Blades & Lightning spear whenever they come off cooldown

Firewall is a really good leveling skill. It's just never been able to scale it's way into the endgame. Diablo 4's endgame calls for fast builds that deal instant damage, which just isn't Firewall. Except for now, due to broken seasonal powers, Firewall has the strength to smash shit and can do it in a 1 attack teleport setup with the Perdition helmet.

The whole jist is you use this power called Mana shield that drops your health to like 20, but gives you 10,000 mana as your life/resource pool. If you don't take damage for 2 seconds you get 5000% mana regen so it's pretty chill. Then we slap on two extremely resource intensive powers, power siphon and advanced techniques, that together grant you like 10-20x damage and let err rip. When you are feeling cheeky you can cast 3 firebolt and get a nice burst of 60% damage for 5 seconds.

This is an infernal horde season, so firewall will be really solid as you can lay out Firewalls across the whole arena and melt everything as they spawn. 10/10 recommend this build.

Teleport Evade Guide

• In S10 you can get -4.0 sec per attack having Flickerstep Chaos Armor
• This allows you to perma TP even with very low cooldown reduction!
• There are breakpoints depending on which boots you use +TP skillranks
• Rule of thumb is you get around 4-5% cooldown on top per teleport rank
• This means you can multiply your TP Enchant CD times 0.82 with 5/5 TP
• For Flickersteps you want your Teleport Enchant to show max 3.4 sec
• For Legendary boots with 1.5 Implicit you want to reach 2.0 to be save
• If you only have the base point in Teleport, you want at least 2.7 or 1.7

Blizzards tooltip doesn't show cooldown reduction you get from ranks

Example:
• Tooltip says 2.3sec in town, you have 5 points in Teleport and you use Vex:
• Only added ranks count, therefore you have +7 in your Teleport skill, this means you get another 26% cooldown reduction on your enchantment:
• 2.3 multiplied by 0.74 (1-0.26) = 1.702
• This means even if you attack 5 times per second (every 200ms/12 Frames) you will have permanent Teleport
• Simply multiply your tooltips cooldown by the number shown below:

+1 Rank = 0.95 (5% CDR): TP Skillpoint
+2 Ranks = 0.90 (10% CDR): TP Skillpoints
+3 Ranks = 0.86 (14% CDR): TP Skillpoints/Vex
+4 Ranks = 0.82 (18% CDR): TP Skillpoints/Shako
+5 Ranks = 0.79 (21% CDR): TP Ranks on Chest
+6 Ranks = 0.76 (24% CDR): TP Ranks on Chest
+7 Ranks = 0.74 (26% CDR): TP Skillpoints+Vex
+8 Ranks = 0.72 (28% CDR): TP Skillpoints+Shako
+9 Ranks = 0.70 (30% CDR): TP Skillpoints+Shroud+Shako
+11 Ranks = 0.66 (34% CDR): TP Skillpoints+Shako+Vex
+12 Ranks = 0.65 (35% CDR): TP Skillpoints+Shako+Vex+Shroud
+15 Ranks = 0.62 (38% CDR): TP Skillpoints+Shako+Vex+TP Ranks Chest
+19 Ranks = 0.60 (40% CDR): (maximum)

Chaos Armor

The best Chaos Armors for Incinerate are basically Crown of Lucion or Fist of Fate.

Chaos Lucion is just solid. Shroud of false death is good, but since we don't need the life it just becomes a chest with all stats and +1 to all passives. All stats is great for paragon reqs and damage overall, and the +1 to passives is great for burn builds, ballpark 40-45% damage. But Lucion is 90% and has a cooldown roll. So sorry Shroud, move aside.

I opt for Chaos Flickersteps because it makes getting the 1 attack teleport evade incredibly easy. If you use Chaos Fist of Fate over these, you can get the 1 attack teleport evade, you will just need to triple crit your evade CDR on boots and likely want to drop glass cannon off amulet for Cooldown.

Seasonal Powers

Mana Shield gives us 10,000-15,000 max mana and that becomes our Life and Mana source. If we don't take any form of damage for 2 seconds, we activate 5000% mana regen.
• You are basically unkillable with this as long as you had good mana regen (Why we have Wizard Blizzard for 500+ a second)

Advanced Techniques grants us increased core damage per rank we have in the skill, at the cost of costing way more mana to cast. Which is not a problem due to mana shield/Inferno. Ranks to core/Firewall are EXTREMELY IMPORTANT. Can Provide 8-10x damage.

Power Siphon grants us 2x core damage, at the cost of reducing our max mana by 20 per cast for 6 seconds. This max mana reduction effect stacks, but the entire stack doesn't refresh upon cast. It's like a rolling amount. Again, because of mana shield... we are moisturized and unbothered.

Explosive Combinations - casting a basic increases all of our damage by 20% for 5 seconds, stacking up to 3 times for 60%
Every 5 seconds you will cast Firebolt 3 times and then go about your business until it expires. In farm content you can probably just ignore doing this.

No Flameweaver

Nah. Too big a damage loss for a season where all the Seasonal powers are only good for scaling core skills

Elixir/Incense

Elixir - Advantage II for 15% attack speed
Incense 1 - Sages Whisper for 100 Intelligence. Use 60 All stats one if you need to hit paragon reqs
Incense 2 - Song of the Mountain for 300 armor
Incense 3 - Soothing Spices for all resistance, max all resistance, and some armor
