[Coda Hirudo] Build Guide – Corrosive + Blast (Crit & Status Hybrid)
(Tested with [Oberon] + Hound Primer for Maximum Effectiveness)

The [Coda Hirudo] is an enhanced version of the [Hirudo] sparring weapon, featuring an Electricity progenitor, making it an excellent candidate for a Corrosive + Blast build. This setup is designed to strip armor, deal devastating crits, and provide consistent self-healing, making it particularly effective for tanky Warframes like [Oberon], [Inaros], and [Nidus].

Build [Overview]
This build focuses on:
✔ High Critical Chance & Crit Damage
✔ Strong Status Effects (~72%)
✔ Corrosive for Armor Strip, Blast for Crowd Control
✔ Sustained Healing from [Hirudo]’s Passive (Life Steal on Crits)
✔ Perfect for Tanky Warframes that stay in melee range

This build has been tested with [Oberon] and a Hound primer, ensuring strong synergy with armor strip and healing support.

Mods Breakdown
Critical & Scaling Mods
[Sacrificial Steel] – Boosts critical chance, significantly improving red crit potential.

[Blood Rush] – Increases critical chance based on combo multiplier, scaling to consistent red crits.

[Organ Shatter] – Enhances critical damage for bigger crit numbers.

[Condition Overload] – Increases melee damage per unique status effect on the target, scaling damage rapidly.

Elemental Mods (Corrosive + Blast)
Since the Electricity progenitor provides a default Electricity element, we add:

[Virulent Scourge] – Adds Toxin (combines with Electricity for Corrosive).

[Volcanic Edge] – Adds Heat.

[Vicious Frost] – Adds Cold (Heat + Cold = Blast).

With this setup, Corrosive strips armor, while Blast provides knockdowns for better control in melee combat.

Bonus Utility
[Galvanized Elementalist] – Provides additional elemental damage and a stacking buff when inflicting status effects.

Stance Mod
[Brutal Tide] – Fast, aggressive, and fluid stance that fits [Hirudo]’s rapid strikes.

Arcane: Melee Vortex
Melee Vortex (Rank 5) – Creates a [Vacuum] effect, pulling enemies into your melee range. This greatly enhances crowd control, allowing you to hit multiple enemies at once and apply status procs more efficiently.

Best Playstyle & Synergies
✔ Use a Primer (Tested with Hound) – A status primer companion applies multiple status effects for extra [Condition Overload] scaling. Hounds or weapons like [Epitaph] work well here.
✔ Ideal for Tanky Warframes – Works perfectly with [Oberon], [Inaros], [Nidus], [Revenant], and [Rhino], as they can stay in melee range and benefit from the constant healing.
✔ Build Combo Multiplier – [Blood Rush] makes red crits consistent with higher combo counts.
✔ Heavy Attacks for Execution – With 5.9x Crit Multiplier, heavy attacks delete tougher enemies.
✔ Melee Vortex for Enemy Clumping – Helps control crowds, ensuring you can hit multiple enemies at once.

Final Thoughts
This Coda Hirudo build excels in high-level content, Steel Path, and endurance runs. The synergy with tanky Warframes, self-healing, Melee Vortex crowd control, and Corrosive armor stripping make it an unstoppable melee powerhouse.

Perfect for aggressive melee playstyles! 🔥
