[Verdilac]'s special Tactical Combo (block + melee) shoots innate toxin projectiles which currently have an unusual damage calculation where [Condition Overload] is multiplicative with other +dmg sources ([Primed Pressure Point], Nira's mods, arcane [Fury]). In addition the projectile damage scales off your combo counter but does not consume combo to use.

INFLUENCE UPDATE
Now that Melee Influence exists, we mod electric so it deals electric status on light attack direct hits but turns the innate toxin projectiles from Neutral Block combo into Corrosive, which means you deal Corrosive + Electric simultaneously with block combo and spread this in 20m. With green shards, this lets you full strip the map and nuke with electric procs.

Mod Breakdown:

• Condition Overload - compulsory mod since it is multiplicative to +dmg for the projectile, and increases with more status effects e.g. +600% damage at 5 statuses (which can be achieved with Verdilac alone) or +1200% at 10 statuses (which can be achieved with combining a primer and Verdilac's innate statuses).

• Organ Shatter - compulsory mod for crit damage

• Weeping Wounds - useful to increase status chance to 126% at max combo

• Blood Rush - compulsory for crit chance (162% at max combo)

• Primed Fury - attack speed affects regular combo gain and the animation of projectile throwing. Flexible for [Berserker Fury] or drop from build entirely if you run external attack speed (e.g. arcane strike or warframe ability buffs like volt, gauss, warcry).

• Primed Pressure Point - Condition overload is MULTIPLICATIVE with other +dmg sources. If you have any +dmg source from outside e.g. Arcane Fury/blade charger, you can drop this mod entirely for Nira's Contempt or Gladiator might

• Primed Smite Grineer - further multiplier to both [Condition Overload] and +dmg, meaning with +600% from CO (5 status), and +55% from smite. In addition, smite double dips DoT proc damage to give it a second +55% boost, or 2.401x final multiplier and triple dips on the spread influence DoTs.

• Shocking Touch - required to make electric + corrosive

Other flexible options - if you drop Primed Fury due to external sources, or hate faction mods, you can run any of the following alternatives:

• Gladiator might - increases crit chance by 110% at max combo and crit damage by 60%
• Sacrificial Pressure - further boosts crit chance
• Primed Reach - helps build combo but does not increase the radius of projectile or gas clouds
