The idea of the build is to go CI with Incandescent Heart. CI gives is Chaos damage immunity, and Incandescent Heart makes it so that 25% of the elemental damage we take from hits is taken as Chaos damage, and since we're immune to that, we straight up mitigate 25% damage. Combined with Ruby, Sapphire and a Topaz flask which make us take 20% less damage of that specific element, makes the build very tanky.
Phys damage is mitigated by max block, high armor, and in the future, Endurance Charges, I say in the future, since the current iteration of the build has no way of generating them.
Aegis is another big part of the build, has high Armour value, good block, and you recover energy shield equal to 2% of armour when we block, being max block we can sustain ES pretty much all the time. The Divine Shield Keystone also is a great addition to the build.
Algor Mortis is the go-to glove for this build. We will chill enemies with Frost Shield and while enemies are chilled, we can Sap them to give us a big defensive buff, since Sap reduces the damage enemies do by a considerable amount. It's also fantastic offensive wise, since enemies that we chill take increased lightning damage.
For jewels there is not a lot of room for customization I'm afraid as all of the jewel slots are used up by unique jewels, so we don't get a lot of crit multi.
We're using a Militant Faith under Dominus to get the "Inner Conviction" keystone which gives us 3% more spell damage per Power Charge, and at the moment we're rocking 8 power charges. This is socketed next to Paint Attunement and also gives us a decent chunk of Aura Effect and Reduced Mana Cost of Skills, thanks to devotion.
To reduced the Duration of Storm Call and have it strike the ground as soon as possible. I've opted to go for a Magebane Impossible Escape and take Exceptional Performance and the 2 other small points, reducing duration of Storm Call by 25%.
Forbidden Flesh & Flame which gives us Heart of Destruction is a very nice QOL and DPS increase. The more AOE the better, and Convergence is amazing for this build.
