1. Anti-Immortal Build Release Disclaimer
Since I released the Immortal craft in March 2018, there has been an influx of Immortal crafts into the arena. Based on my observations, the Immortals need a strong counter build. It isn’t a lot of fun for some players to have to play 10+ rounds before getting their first defeat. I had strongly considered requesting a nerf to the Immortal build but decided this is the better method. Every round takes 30 seconds, which can make some matches take up around 5+ minutes for each match. The craft below can defeat Immortal and Blood magic builds within 3 to 4 seconds of gameplay. 
2. History
The first barrage theory craft was @luisfsk and the first Anti-Immortal Barrage Craft was created by @ZARAKI. The one I am providing below is a concoction of various tests to achieve Anti-Immortal Craft capability.
3. Mathematics Behind Anti-Immortal Build
3.1 Power and Speed
The entire focus of this build is to place as much damage onto your opponent as quickly as possible. This is one method that works - there are many other ways you can improve this craft.
3.2 Sets
Cosmic Power set: Increases damage of projectiles that pass through the Time warp (OH Secondary) for 12.5%x3 or an increase of 37.5%. Increases MP by 25%/rank or 75% increase to MP.
Demonic set: Reduces healing by 6%/ rank or reduced by 18% (FOCUS) for five seconds and increases damage by 20%/rank when enemy below 25% HP or 60% more damage.
Electrified set: Major point for this set is you gain 5%/rank to paralyze (Elemental Critical Chance) or 15%. Using Shock Wave ring with Electrified Bonus, you gain 30% increased damage to stunned opponents (75%x40% for one set in PvP).
Angelic set: Gain 5%/rank damage and APS increase for Skills with Cool downs less than 1 second. This gives 15% increase to damage and APS boost.
Aether Drain set: Focal point for this set is you gain 5%/rank to paralyze using Shock (Elemental Critical Chance) or 15%. Gain increase to MP by 25%/rank or 75%.
Defiant Set: Only gain is 25% in damage from this set.
3.3 Epic Skill Points
Epic Skills:
Barrage Increases damage by 5% per point. This craft has 19 points in barrage skill or 95% damage (5%x19). You also gain 2.5%x19 or 47.5% increase in APS. In addition, you gain 3%x19 or 57% increase in projectile speed and 1%x19 or 19% reduced resource cost. Barrage is straight to opponent / seeking.
Timewarp Increases damage by 5% per point. This craft has 7 points in timewarp skill or 35% damage (5%x7). You also gain 1%x7 or 7% increase in Spell Size. In addition, you gain 2.5%x7 or 17.5% increase in projectile speed and 1%x7 or 7% Spell Duration.
3.4 Dependent Bonuses
BONUSES: These are huge for the two Dependent affixes. Epiphany bonus gives 20% damage increase and Electrified Bonus gives 30% damage increase to stunned opponents (Elemental critical - posted build has additional 81.3% damage during stun).
3.5 Legend Affixes
Multi attack: Gives 50% damage to MH attacks
Damage to Elites: Gives additional damage to players 17.4% more in craft posted.
Glass Canon: Gives Max 18% per legend affix increase in damage. Arena cap is 100% Glass Canon. This affix reduces your HP but we do not need any HP for this craft. Empower talent is similar in that it gives 2.5% per talent point (this build has 7 Empower or 17.5% increase in power).
Push The Limit: Gives Max 18% per legend affix increase in damage. Arena cap is 100% PTL but this increases the cost of spells by requisite PTL percentage.
3.6 RANGE
Range: Range from this craft is approximately 60 yards or 60% of the arena.
3.7 Stat Point Investment
All Stat in Power
4.0 Damage Reduction
None - Isn’t it great? You kill or get killed in 3 seconds.
5.0 How to use
At start of each match, turn character around to face opponent, press Timewarp followed by holding down Barrage (press trophy silence/root/slow when your opponent comes into view). You will need to be fast vs some players. Some players camp and you just walk to half of arena and hit with barrage. You might have to slightly move out of the way when the torrents from CV start getting close but the match was generally over by the time they spawned. It took me a bunch of matches to figure out the timing. I also threw 19 matches trying to get the chemistry right for this build.
5.1 Artificial Intelligence Controls/Settings
AI Controls Might need to experiment some but this works.
