I did some math with http://fogz.mine.nu:8080/poe_reserved_calc/
alpha howl with the already 8% mana reserve we have can do grace+determination+purity of fire and reduce mana, drop vitality and have amazing near 20k+ defense.
Doing this can also let us refund some points that were used on endurance charge to get it at around level 85 and pick up the new damage over time 1.4% life regain and grab the extra .8 by vaal pact.
Grabbing iron reflexs with alpha + this plate only makes it even better aswell, now add the level 22 grace+ determination and ultimately can go for a really good str/dex armor.
now you maintain 20k+ armor NO endurance charges, also do more burning damage
you can pretty much not worry about using enduring cry anymore and just use flamability.
Now you can use...
Any weapon you want in main hand no need for gem support
Helm 4L (alpha howl) Reduce mana - Grace - Determination - Purity of fire
Shield (rise of phoenix) 3L cast when stun level 20 + ice nova level 20 + shock nova level 20. I have a 15% cast when stun and stun happens a lot so works really good and gives a lot of damage
Plate 4link (belly of the beast) or a good str/dex one. Arc - Chain - Blood Magic-Faster casting If 5link use added chaos damage. (edit for future for facebreakers idea)
Gloves 4L Cast when damage taken - molten shell - enduring cry - item rarity or life leech
Boots 4L Flamability - Faster casting - blood magic - Increased area of effect
So yeah, I'm going to grab the new passives and iron reflexs and try alpha and dropping vitality + the 1 endurance charge and str nodes when I reach level 85ish or maybe 88ish. Should make this build super tank, more damage and no need to spam enduring cry on mobs and can let it be used with CWDT
level 82 atm, took 2 bandit rewards and 1 passive point goal for the above at level 88 is this tree below
EDIT: By the way I have a crazy idea with this, with the above set up you get to pretty much use any weapon you want. and the chest is just being used for arc right? What if...Facebreakers + no weapon + 5 link chest with infernal blow + Multistrike + Melee Splash + Melee Physical Damage + blood magic or faster attack if theres a way to use mana for Infernal blow.
Drop determination for hatred will still be able to use endurance charges+ grace for more defense than ever.
I read facebreakers do around 40k dps AOE with melee damage on full life added to the above with hatred aura. We could pretty much do same thing with righteous fire on top :O. And apparently cyclone is even more dps with facebreakers. Resolute technique is only 3 nodes away as well. Melee splash with facebreakers chasing down mobs while can either cast on stun or cast on damage ice nova+ shock nova for EE just sounds insane....I clear amazing with RF alone and with facebreakers they could be the answer to bad map rolls that can't use RF.
But yeah I posted this here hope you reply I did the math everything seems to work maybe you can see a reason it wont let me know : )
