Yo waddup m8s,

Here is my Dog-Lover Equinox Build, Equilord.

This is a completely fun/meme build, of which the goal is to buff your pet up to Max Damage and letting them do all the killing.

I chose [Equinox] over other frames, because of her ability to proc the Slash status effect for the juicy +150% bonus damage by the Hunter Set.
That is why I dropped any Ability Strength for Duration/Efficiency and Range, as we don't need the slash procs to do any damage, just them existing on as much enemies as possible.
You could choose [Shepherd] as an aura to make your pet tankier, but his would require a forma, so I just stick to [Energy Siphon] or [Corrosive Projection].
You can subsume either the second or third ability, as both don't really do much. Two viable options include Master's Summons (for obvious reasons) and [Ivara]'s Quiver (so you don't have any problems with enemies targeting you)
I recommend Arcane Guardian for some added survivability, tho this is a flex-slot.
Another very important part is Theorem Infection, further buffing your pets damage.
To activate this arcane I use this Kitgun-Build.

For the complementing pet I use this special Helminth-Charger build using the Strain Set.
Should you decide against the charger you have to drop the Strain Set.
A [Vitality] should make a good replacement.

May the grineer fall in your (companion's) wake.
