Endurance focused viral slash semi-auto Fulmin build for armored Grineer/Corrupted without external armor strip.

Mod Breakdown:

• Galvanized Chamber - mandatory multishot mod

• Galvanized Aptitude - mandatory damage mod, giving +80% dmg for each unique status affecting the target. Having just three status effects from innate elements gives +240% dmg (3.4x multiplier), and on Fulmin's Semi-auto mode specifically, this is MULTIPLICATIVE to other base damage sources like Serration/Arcanes.

• Internal Bleeding - [Fulmin]'s semi auto mode has forced impact on every shot, meaning every shot has a 70% to make a slash proc, which bypasses armor. The fire rate just needs to be below 2.5 for maximum slash chance. This means you cannot run any fire rate buffs that exceed 44% (either from mods or external buffs like Haste mote, Harrow etc, arcane acceleration etc).

• Critical Delay - mandatory crit mod

• Vital Sense - mandatory crit mod

• Primed Bane of Corrupted/Grineer- double dips DoT for final +140.25% dmg boost (2.4025x multiplier), separate to Serration and G.Aptitude. If you don’t like banes, you can swap this out for Serration, Bladed Rounds, Hammer shot.

• Arcane - Primary merciless procs on slash proc kills, while deadhead requires direct headshot kills.

OTHER VARIANTS:

For corpus - you can either run Viral Electric (best when shield/armor stripped) or Radiation Toxin (no shield or armor strip). For viral electric, just swap [Internal Bleeding] for stormbringer or high voltage. For Radiation toxin, swap Internal Bleeding and Rime Rounds for Wildfire + High Voltage/Stormbringer.

For thrax/acolytes/infested (without armor strip) - run raw corrosive by swapping Internal Bleeding and Rime rounds for Infected Clip + Vile Acceleration.

For Zephyr - simply swap [Internal Bleeding] for [Hunter Munitions].
