Mag Prime - Endgame Setup

What is incorrect in other Mag Prime guides:

• too much efficiency
• no Counter Pulse
• wrong arcanes
• only good to pwn low level enemies
• Vitality mod, are you serious?
• low duration together with "endgame" label

Why is this shitty guide 'better' and without Strength mods?

• because i have tested all mods in Arbitration / Sorties / Kuva Survival / Lich hunting missions, and this build is result of optimization. It turns out that Power Strength builds don't give enough performance for the sacrificed utility

Breakdown of setup - why you should use these mods:

Counter Pulse

• The most important mod, it will turn game into easy mode. Why are you not using it already? You cannot die when enemy is not shooting. Scales with Range and Duration.

Primed Flow + Streamline

• Spend max 2 slots for Energy Efficiency, even with just Primed Flow you will be fine. Use Zenurik school - Energizing Dash to have enough energy during whole mission.
• Fleeting Expertise - costs a lot of Duration and that hurts this setup. Streamline is better.

Primed Continuity

• As mentioned, duration is very important and useful, one Primed Continuity is enough.
• Some tough enemies, Bursa/Lich/Auditor/Demo Units, have ability duration reduction on themselves, but this mod gives extra second anyway.

Natural Talent

• Big difference in your performance, try it out.

Adaptation

• Your 4th give you overshield already, you dont need more shield. Adaptation however multiplies your effective shield points.

Stretch

• After longer testing, one [Stretch] gives enough range you need. 2nd is not too big, 4th is not too small, 3rd with with duration will disable big area. Perfect!

Corrosive Projection + Vigilante Pursuit

• Currently best combination, [Enemy Radar] mods are very very useful, previously I was running [Enemy Radar] with some Drift mod, but this is better. CP makes game easier and 3rd stronger, VP gives same enemy radar plus enhances criticals. Neato

Optional Slot

• Fracturing Crush is optional, it is more mean to root Infested and strip armor of everybody else, in easy-medium missions you don't need it, but in endurance missions you might want it.
• Feel free to replace it with something you need

Arcanes

Yes:

• Toxin - must have against Infested
• Slash - quite needed against high level Grineer
• Magnetic - very good to have, depends on mission
• Radiation - very situational, probably only Sortie
• Damage/Crit - if you really want, then yes. But you don't deal damage when you are dead, so use Arcanes to cover your weaknesses.
• Velocity - if the game mode is easy for you, the add velocity to speedrun the mission. However I used other frames for that.

You don't need:

• Energy, Health, Shield, on Hit, on Damaged, kind of arcanes.
