 The Fulminator | Semi-auto Viral Slash Endurance Fulmin + Variants 
 Introduction: 
 Endurance focused viral slash semi-auto Fulmin build for armored Grineer/Corrupted without external armor strip. 
 Playstyle: 
 
 Mod Explanations: 
 
 
 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. 
 
 
 Building for Other Factions 
 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] .
