>Introduction: [Larkspur Prime] is pretty good ong. A very convenient weapon, when modified with basic mods, can be a deadly weapon to destroy crowds within seconds. This basic build builds elemental damage Radiation and Viral, and although I haven't tested it, but any other elemental damage could do fine.<

**>IMPORTANT NOTE: This build is good for almost all enemies other than eximus units and similar. It takes a lot longer to take down eximus units, however in order to exterminate them, just use a method that can deal massive amounts of damage in quick bursts, such as a strong melee or warframe ability. You can also use [Voidrig]'s 4 to literally 2 shot eximus units with the most basic damage mods.

The mods are extremely cheap and are pretty easy to get, and it's satisfactory for almost if not 100% of missions requiring necramechs like open world bounties in Cambion Drift, Plains of Eidolon, and Orb Vallis. It's also quite useful in Thermia Fractures. It does not have trouble draining health from any enemies, and is ideal for any level mission (not sure if the levels of the bounties scale, I don't think so, but if it does, then this build will be less and less effective.) It's still highly effective for enemies around level 60.
