Acquisition[]
- This mod can be purchased unranked from Baro Ki'Teer for
140,000 and 
350. Note however that Baro Ki'Teer's stock changes with each appearance, and may not have this item available at every time.
Notes[]
- Has no effect on Corrupted and Narmer Grineer (e.g. Corrupted Lancer, Narmer Lancer).
- Despite being listed as a multiplier, it will stack additively with other sources of Damage to Grineer.
- For example, if you had a Riven Mod with x0.5 Damage to Grineer and a max rank Primed Expel Grineer with x1.55 Damage to Grineer, you would have a 1 - 0.5 + 0.55 = x1.05 multiplier for damage against Grineer with both mods equipped.
Patch History[]
Update 34.0 (2023-10-18)
- Changed the Faction Damage Mod (includes Bane, Cleanse, Expel, Smite, Railjack, and Riven Faction Stats) descriptions to use multiplier instead of percentage based stat formatting. Damage values have not changed! Just the way they are communicated.
- For example: Smite Corpus (at max rank)
- Was: “+30% Damage to Corpus.”
- Now: “x1.3 Damage to Corpus.”
- This change better communicates how Faction Damage is calculated, since calculation occurs when you hit the enemy, as opposed to when you shoot like other damage sources (since it needs to know what Faction is being hit). For that reason, multipliers apply to final damage as a whole and not just part of the formula!
- For example: Smite Corpus (at max rank)
Hotfix 23.9.1 (2018-09-27)
- Introduced to Baro Ki'Teer's rotation.

Why in the world would I want to buy all 4, plus put in the endo if Augur Pact gives more damage to everything?
Augur Pact only adds to base damage. And stacks with Hornet strike
Expel mods increase TOTAL damage. That is the percantage is added AFTER the base and elemental damage has been added up.
Because Augur Pact + Hornet Strike equates to about 30% increase to base damage; Primed Expel equates to 1.55% increase to total damage, as well as 2.25 increase on status DoT (Like Gas & Slash procs). The difference in DPS is astronomical. Augur Pact does next to nothing; Primed Expel can potentially triple your DPS, if you're running a status DoT build.
^Well, right concept but your numbers are a bit weird.
Yes, compared to just having![Mod TT 20px.png](data:image/svg+xml,<svg xmlns="http://www.w3.org/2000/svg" width="12" height="20"><rect fill-opacity="0"/></svg>)
Hornet Strike adding ![Mod TT 20px.png](data:image/svg+xml,<svg xmlns="http://www.w3.org/2000/svg" width="12" height="20"><rect fill-opacity="0"/></svg>)
Augur Pact will result in an overall +28.125% increase in damage. A Primed Expel mod on the other hand will result in a +55% increase in damage, plus a +140.25% increase to 
Toxin, 
Heat, and 
Slash proc damage per tick, and a +272.388% increase to 
Gas proc damage per tick.
Considering this is an old comment, i will reply just to help new players. Faction mods increase the damage after every other buff, this means after arcanes, aura mods and frame buffs.
Example: if you have a weapon dealing 100 damage with augur pact+pistol amp and rhino roar +50% it will deal
1a)100+90%+27%= 217 *(roar) 1.5 = 325. Now if the same weapon is buffed with primed bane mod+pistol amp +rhino
2a)127*1.55*1.5=295.
Yes it seems usless but if you use a riven:
for example having a simple riven with +200% damage
1b)100+200%+90%+27% X 1.5 = 625
2b)127+200*1.55*1.5= 760
Considering you can even include the crit damage in this calculations you can understand that you will have a nice increase in damage using faction mods.
And the most important advatage using primed bane mods is the insane multiplier on toxin and slash procs.
sorry about the stubbii info, (literally) will take forever if want to fully add the info for it ._.
