Posted Jan 25, 2016By dropping In-geom he can get rid of Diamond Skin (don't need the reduced arcane power because you aren't casting super fast from the In-geom proc) and use Magic Weapon Deflection (which pairs well with Ashnagarr's bracers). It's all means to gain the toughness needed for the slightly higher greater rifts (since you can't keep Diamond Skin up 100% in the higher ones). You can't benefit from the Goldwrap / Boon of the Hoarder combo in greater rifts because they don't drop gold (which most Flash fire builds seem to use).
What's interesting is the choice to keep Nemesis. This could be swapped for Aquila for more toughness but I guess there's a balance here. Also alternatively, wouldn't Aquila give more toughness than Ashnagarr's (which could still be used with nemesis by wearing them)?

Posted Jan 25, 2016Maybe you need to add some gameplay tips to explain more. As it stands, its is not viable at 65 let alone over that. p600+ and I got juiced on 65. Normal flash wiz does better, at twice the speed.

Posted Jan 26, 2016They are doing it all wrong, WoW with EB is supposed to be a mobility/burst build. Not a "wait for my cool-downs to do mediocre damage with no sustain" build. You NEED either Aether Walker or In-Geom in the cube, the furnace just doesn't do anything for this.
The reason EB does good damage with In-Geom is because of the overlap on multiple casts. This build doesn't use in-geom, nor does it use Obsidian Ring to lower cool-downs significantly so you are missing out on at least 2x the damage from EB, also procing your lighting tal rashas buff with a signature spell is FAR inferior to procing it with black hole. Having spectral blades-barrier blades in place of arc lighting and black hole in place of energy armor will allow for you to proc arcane meteors more consistently, while also giving a defense boost as well. Dropping the nemesis bracers for Shame of Delshere in the cube will solve any AP issues you might have with spenders, and swapping Furnace to Aether walker will increase survivability MASSIVELY due to having unlimited teleport, which also stuns enemies for 1.5 seconds AND does damage, AND CAN ALSO PROC TAEGUK.
Not sure where this build is getting damage OR survivability from. I'd love to see a video of this doing a GR65 at a resonable speed with this gear equipped. I'm nearly Paragon 800 right now and I have ancient everything equipped and nearly perfect stats on gear with Augmented items and with these items I wasn't able to do a GR65, or even a 60 without many deaths. I even tried some defensive gem in place of BoP and it was still useless.

Posted Jan 26, 2016I dont know, I farmed like 20 60grifts with this build and i averaged 4:30 mins per rift. I didn't die a lot, you have two cheat death and quite some survivability from deflection, dominance and the bracers. Para 650.

Posted Jan 26, 2016This build works for blatty because he has nearly perfect gear with almost 2.5M sheet dps and his effective dps is even higher. He kills before the monsters kill him and thats his goal. If you don't have such high dps you will suffer the survivability issues pepole are facing and you will need to make modifications suggested by others or farm lower. I honestly found the regular tal rasha fire flash wiz worked better at gr60 than this build, neither of these worked for me at 65 due to the reasons I mentioned above.
so, if you want to be successful get your dps higher, ridiculously higher.

Posted Jan 26, 2016Build is very solid. You need to be fairly geared, but come on people... If you wanna speed farm like 60s, you need to be geared. Currently 650 paragon on season with 999k sheet dps and no ancient Wand, averaging 4-5 min runs. Pretty good imo.

Posted Jan 26, 2016His effective DPS isn't good because he's not getting any overlaps on his Explosive Blasts which do all the damage with a WoW build. You NEED 1 second cooldown or less on EB otherwise you don't get 2-3 overlapping and exploding at the same time effectively tripling your dps. It's not hard to figure out if you've ever run In-Geom with this setup, you'd understand in 2 minutes what I'm talking about.

Posted Jan 26, 2016You guys are leaving comments saying this build is great when in reality u guys are just watching him stream it and he is using a clunky as fuck build that doesnt even work good but when combined with playing around the awkwardness of the build it is managable but not good. There are far better builds that are far more optimized and easier to gear than this.... having all that elite damage is good for fighting elites in perhaps regular rifts but in greater rifts if you really want to push for higher #'s u need to skip elites and go for the whites.... big groups of whites... but then again you guys will probably believe whatever you want to believe...
Ps. seriously this build isn't neccessarily bad nor is the gear but the biggest problem is Why the fuck would you use Wand of Woh if your build is janky as fuck switch to blizzard and profit.... with this build... if u want to keep wand of woh switch to a more mobile cdr focused build that allows you to have multiples instances of explosive blast casting at once... by hitting certain break points... hint hint aetherwalker helps in cube.

Posted Feb 3, 2016I'm surprised all this time no one has updated their Firebirds builds like this one. The Firebird's Finery 4 piece set bonus worked fine in PTR, but once 2.4 hit it was bugged along with the 6 piece, meaning the DoT falls off after moving away from mobs no more than 2 screens. This means you have to finish these mobs before moving on, you can't just dot them up and leave it doesn't work, which means In-Geom is much harder to keep up since you have to spend more time finishing mobs.

Posted Feb 7, 2016In-geom definitely falls off at ~60-65 GRs - you just stop killing elites in 5-6 seconds, the uptime isn't enough, and you end up playing without the In-geom buff a big part of the time. I absolutely agree with the general idea of this build, I've reached the same 'conclusions' when I started running Fire/Rasha to speed clear GRs.
I don't understand a couple things in your build specifically though.
1) Why Storm Armor - Scramble? It feels like it's something 'leftover' from the In-geom spec. It completely makes sense in the ultra mobile In-geom "run by and kill" spec, but not here. Even looking at the attached video, you stop to fight elites all the time!
2) Why Bane of the Powerful? Surely there are better options.
Personally, I run this exact build and this exact playstyle showcased in the video, but I run Energy Armor - Energy Tap and Taeguk. I have over 58% CDR, which means I never lose my Taeguk stack (unless something really unlucky happens). I get more damage from Taeguk than I would have from Bane of the Powerful, and I get armor from it which scales very well with Energy Armor. I get 20 extra arcane power which means my Aquila buff uptime is somewhat better, but the other runes probably work good too (I haven't tried them).
I mean, I'm trying to see what does your build have better than mine, and it looks like... nothing? Other than the CDR requirement, but 58%+ isn't crazy hard to get or anything (you don't even need it on all slots)

Posted Feb 15, 2016What about Primordial Soul off-hand http://us.battle.net/d3/en/item/primordial-soul
"Elemental Exposure's damage bonus per stack is increased to 10%."
It seems like a big damage increase, since Elemental Exposure would provide 40% more damage (instead of the default 20%).
Why is it never used?
