This build destroys Hemocytes in the Plague Star event. The other builds up on overframe are universally terrible except for one or two. I hope this one gets noticed.

Some gripes: People using 60/60 mods are retarded. The Hemocyte is immune to status effects. Also, blast damage is superior to corrosive because of [Primed Heated Charge]. Overframe needs a better system for top builds, because too much trash rises to the top.

The Build

We use blast damage instead of corrosive. The Hemocyte is 50% vulnerable to blast, and 75% vulnerable to corrosive, but you can use Primed Heated Charge with blast, which puts the total damage over corrosive.

We use Ice Storm instead of Deep Freeze. You only gain 40% more blast damage vs. 90%, but your magazine size increases 40%, from 12 to 17 rounds. With Anemic Agility and Lethal Torrent you will do more damage per reload when you dump all 17 rounds into the Hemocyte.

Focus School
Use Unairi, specifically for its second ability Caustic Strike.

Playstyle
When the Hemocyte spawns:

1) Go to Operator Form.
2) Cast 2 Caustic Strike on the Hemocyte (you do not need to hit the vulnerable spot, just hit it). This will strip 100% of its armor.
3) Wait for one of the three heads to become vulnerable. Equipping an Archwing that can stealth or avoid damage while hovering in the air is ideal here.
4) Unload on it with Pyrana Prime when a head attacks.
5) Watch it die very quickly.

Ideal warframes: [Nova], [Volt], [Wisp].

Subsuming Eclipse will increase your damage substantially if you keep it active during step 4.

This build is capable of soloing the entire Plague Star event, if you want to do that for some awful reason.

Enjoy!
