The [Ambassador] has been my white whale, for over 2 years. It is one of the most striking weapons in the game. Aesthetic, sound design, concept, all fantastic. Long have I hoped we will one day see a Tenet variant. I've used this weapon for a long time, unable to take it any further than star chart steel path, until today.
Finally, this corpus weapon has become as deadly as it deserves.
Am I thrilled with having to hit headshots? Not really. I've always preferred to go for center mass, but The [Ambassador] has so much ammo, fires so fast, and is so accurate, it actually works wonderfully with a headshot build. Suck at hitting weakpoints? That's ok! This build is still for you!
Corrosive will melt enemy armor, and [Cryo Rounds] will freeze enemies in place, as well as enhance your critical hits. Most targets will be just that for you, stationary TARGETS. Running a companion with a cold status primer can make things go even smoother, like Artax or Verglass Prime. (These are absolutely NOT required.)
Primary Acuity and Crux are the required mod/arcane for this build. There is no need to mod for reload, as Crux will keep you from rarely reloading. You're welcome to switch the element to radiation instead of corrosive (as the weapon has innate electricity and MUST be modded accordingly), but I find the light armor strip to be more consistent and helpful. [Critical Delay] is also a flex slot, having extra crit chance is just in case you miss your headshots or a target is turned away from you. You can also easily swap out serration for a faction mod, or spectral serration, as this is an EXCELLENT weapon to run on [Cyte-09].
If you ever roll a riven for this, aim for crit chance, crit damage, or multishot.
If you're insane like me, you can also run purple archon shards for extra electricity damage, to push the weapon even further! (Again, NOT required!!)
I hope you all enjoy, take care Tenno!
