This is my stat stick build for my armor strip and auto primer companion build.

through extensive testing, [Lasting Sting] doesn't appear to have any effect on companion weapons status duration. This could be a bug, so I will try to update the build if that changes.

This is specifically built for applying as many statuses as possible. The [Batoten] was chosen as it doesn't have inherent slash, and most likely the weapon you'd be using on your warframe will apply slash anyway. Puncture and impact then act as just boosting the damage from [Condition Overload] or galvanized mods.

Viral is used here for two reasons: boosting slash damage and offloading viral off of your warframe weapons. This allows you to run things like corrosive on your weapons so that you will deal decent damage to enemies with armor, and still keep that damage when that armor is reduced to 0 thanks to viral + slash.

Heat is the next best option since the companion build will proc electricity by itself already. Heat allows for another separate status to be applied and therefore more damage.

Rad is used for the same reason, another separate stack of status for damage that isn't already on there.

Attack speed is to attack more often, and range is for hitting as many enemies as possible(see Hound companion build).

[Melee Prowess] for status chance to proc more status on basic melee attacks when precepts are on cooldown.

primed mods can be replaced with nonprimed counterparts.
