1. Immortal Build Release Disclaimer
After long and deliberate consideration, I have decided to reveal the Immortal Build. In order to understand the decision, I need you to understand the Immortal Build was leaked to cheaters ~6 months ago who have been exploiting the build in the arena. In lieu of this knowledge, I want every player to have the opportunity to craft and experiment with this unique build.
As @Midlumer and I wrote almost a year ago, the build can be defeated by burst damage play styles. However, burst damage play styles are weak to barrage builds…
2. History
The first theory craft was @Refia. The first Immortal Build was crafted by @Mandelbrot (Paradox). @Midlumer and I followed shortly after Mandelbrot with a reverse engineered Immortal Build. The push was on since a challenge was made by several players a year ago that the arena was not a challenge.
3. Mathematics Behind Immortal Build
3.1 Regen
This is not the traditional regen you utilize in the game to have 3K HP regen/second… You achieve regeneration through the usage of Alchemy Resource Mythic + Permafrost Set Affix or 3x MP Absorb legend affix. Your enemies damage regenerates your HP/MP. You can supplement the craft with traditional Regen but it is not required. Using Permafrost Set Affix or MP Absorb does the following: Damage received is first absorbed before being reduced by damage reduction. You need to take damage to stay alive. You cannot craft an infinite reduction / regen loop (i.e. Never die) - I have tried the mathematics and it’s not possible.
3.2 Damage Reduction
You will want a high amount of continuous Damage Reduction. Continuous Damage reduction is something that is always in effect like armor, resist, defiant, and MP Absorb. Variable Damage Reduction would be; Skullshield (10% reduction / active skull) but they die or get purged easily, Shield wall only lasts a few seconds also, Equivalence works until your HP begins to get displaced.
Damage Reduction is Multiplicative. Look at the example below.
Armor 82% (1-0.82 = 0.18)
Resistance 35% (1-0.35 = 0.65)
Defiant 25% (1-0.25 = 0.75)
Permafrost 16% (1-0.16 = 0.84)
Total continuous Damage Reduction =
1-(0.18x0.65x0.75x0.84) =
1-0.07371 or 92.6% Damage Reduction
Skull shield can provide an additional 30% (3x10% each) Damage Reduction when they are active. From the simplified equation above you can see the additional gain in reduction while they are active. Example Below:
Damage Reduction Including Skull shield=
1-(0.18x0.65x0.75x0.84x0.7) =
1-0.0516 or 94.8% Damage Reduction when skulls are active.
3.3 Power / Damage Concept
For a majority of players, the Immortal Build will draw you from X to XX rounds. For every match that ends in a draw, power is increased by 25%. In my current build, my Power is 584.
Draw 1 = 584x1.25 = 730
Draw 2 = 730x1.25 = 913
Draw 3 = 913x1.25 = 1141
Draw 4 = 1141x1.25 = 1425
Et cetera
3.4 Effective Hit Points
You want high Hit Points and high Damage Reduction for an effective craft. My current build has 29.6K HP. Using the damage reduction example from above, it will take a hit of ~401,574 (29.6K/0.07371) to kill it before damage reduction. The single hit that kills that craft will likely be around 30K when you look at the combat log, if your HP is ~30K.
4 Ok… Ok… Now Shut up Scooty and spill the beans 
One of my old crafts below. You can create many variations of this build going with different sets, mythic combinations or you can invest into resist instead of Armor to avoid Bloodless Trophy AR Pierce effect. You can also add one perseverance affix if you’re worried about bleed builds (remove 10 skulldraga from Offhand and replace with 40 Perseverance). I have had one of these crafts up to 43K HP, 600 power and 92% Damage Reduction.
