Empty Slot is for Galvanized Reflex - this allows you to hit permanent x8 combo in combination with [Corrupt Charge] after getting a few kills, without requiring [Rauta] or manual combo gain.

EVOLUTIONS

Evo 2: Edge of Justice
Evo 3: Seismic Slam +100% slam radius
Evo 4: Critical Parallel +16% cc and +1x cd

MOD BREAKDOWN

[Sacrificial Pressure] + STEEL: Set bonus boosts both mods, but most importantly boosts the crit chance bonus to +550% allowing [Magistar] to hit Tier 3 red crits. Note an acceptable alternative is [Primed Pressure Point] + GALVANIZED STEEL, which results in slightly higher crit damage but lower crit chance and overall both lower consistency and average DPS, especially when you add a riven or violet archon shards. Without a riven OR archon shards giving extra Critical Damage, Galvanized Steel has slightly higher overall damage than [Sacrificial Steel], but the moment you add a CD riven OR a single Violet Archon melee crit damage shard, Double Sacrificial becomes better again.

Use this spreadsheet to check exactly which versions of pressure point/steel are better, in addition to other mod choices and riven stats since everything is dependent on your frame buffs, shards and other external factors: https://docs.google.com/spreadsheets/d/1L4i6Ax36sfdZoIAMQl5HAmR3K0IfpfRoELrZP6OH6S8/edit?gid=0#gid=0

[Blood Rush]: At 8x combo, [Blood Rush] gives +280% CC, which pushes [Magistar] into higher crit tiers for higher consistency and average DPS.

[Organ Shatter]: Gives 90% Crit damage. NOTE: This is the flexible slot if you have alot of shards.

[Primed Fever Strike]: Gives +165% toxin damage which contributes to raw damage, and toxin damage bypasses shields which is important because enemies with shields like corpus/corrupted have a shield gate that cannot normally be bypassed by slam damage.

SEISMIC WAVE: Gives 200% damage which is multiplicative to Pressure Point/[Sacrificial Pressure]

GALVANIZED REFLEX: At maximum stacks gives 80 initial combo which combines with 30 from [Corrupt Charge] and 30 from incarnon form bonus to hit 140, giving 8x permanent heavy multiplier which multiplies heavy slam damage by 8x. Also gives heavy attack efficiency which effects how much combo is consumed each slam and therefore how quickly you regenerate combo back to 8x before you are ready to slam at maximum damage again.

[Corrupt Charge]: This is a FLEXIBLE OPTION and depends if you have any outside source of initial combo. This is because without [Corrupt Charge], Galvanized Reflex fully stacked only gives 5x combo before incarnon mode is activated, and you need to hit 6x combo to activate the incarnon mode. Running [Corrupt Charge] allows you to hit 6x combo immediately and activate incarnon form to jump to 8x initial combo. Alternatively you can run [Ready Steel] in the Aura, use [Rauta] to gain combo by shooting, block to gain combo or just swing the [Magistar] manually each time you need to reactivate the incarnon form. If you prefer this, swap Corrupt Charge out for Organ Shatter, Focus Radon or Riven.

FLEXIBLE OPTIONS

• [Focus Radon]: Gives more heavy efficiency which stacks with Galvanized Reflex, allowing faster spamming of slams. Also gives some Radiation damage. Slot this over Organ Shatter if you have alot CD on riven or shards
• Gladiator Might

RIVEN
Ideal riven is CD/DMG/CC/IC/TOX/heavy efficiency and slot over [Organ Shatter] (if you roll CD) or [Corrupt Charge] (if you roll IC). Other elements are not ideal but also useable.

ARCANES

Melee Exposure: best for x5 combo slam spam
Melee Crescendo: for x12 slam spam, swap corrupt charge for organ shatter. Use Vazarin grouping or Aero periphery/aero mods to initiate finishers.
Melee Fortitication: for armor memes on iron skin meme Rhino etc
Melee Retaliation: for use on Hildryn

WARFRAME SYNERGIES

For min-maxing damage, run [Nira's Hatred] and Anguish on Warframe, Arcane [Fury] on Warframe and run at least TWO to THREE Tauforged Violet Melee Crit Damage Shards. Use [Tenacious Bond] on a pet.
