This build is NOT linked to our normal [Rubico Prime] build. It's not possible to fit both builds in the same polarity plan.
Primary Arcanes and the Exilus mod should be swapped depending on your playstyle.
All can activate their damage buffs on random enemies or animals roaming in the Plains.
Primary Merciless gives a decent passive reload bonus but the damage buff is nearly impossible to keep active in Eidolon hunts.
Primary Dexterity caps out your swap speed when combined with Vigorous Swap but may require a long range melee weapon to reliably proc the buff.
Primary Deadhead allows easier cap-shots on the Eidolon and gives a reasonable stability boost but can only reliably proc the damage buff on Grineer.
