So I made an experimental build, then I put 4 Forma into a [Zarr] and learned a lot about it. This is the revised build.

The Zarr is freaking awesome. It's like a blend of Tonkor, Bramma, and Drakgoon features. A semi-auto tonkor with a 3-round [Mag] tube, Bramma bomblets, and a shotgun mode a lot like the [Drakgoon] quick shots.

It is fun.

I was able to rank this up in SO and in relic survival missions just fine (with a pure corrosive build), but when I tried it out on level 125 Heavy Goons, it couldn't really accomplish much. After some experimentation, I found that the viral/[Hunter Munitions] combo was the only way this could hope to take down high level content, and it was mediocre at best. This might be best for any content under level 80, and it's a freaking blast at that.

With those last three slots, there are a few options:

• 60/60 viral with Hunter Munitions, as shown, for higher level stuff.
• 60/60 viral with Thermite Rounds (for more status) or Wildfire to swap the extra status for an extra round in the mag, which is nice.
• 60/60 corrosive with the same fire options
• Either 60/60 viral or corrosive with [Hammer Shot], which dramatically increases the status and enhances the frequent yellow crit damage.

This is going to be one of my new favorite weapons for relic cracking and maybe murmur farming. I can tell. And it's so great when you're lobbing shots (with bomblets!) and you're suddenly face to face with a dude, so you hit the alt fire to toggle 'barrage' mode, one-shot him, then switch back.

I had a lot of fun leveling this with [Wukong Prime], armed with only the [Zarr]. With my clone, it would double the cannons, and my clone didn't have to worry about ammo or stagger.

This would also be great wielded by [Atlas] (feet on the ground for immunity to stagger) or [Inaros] with Negation Swarm for status immunity. It's possible to add another forma to the exilus slot for [Cautious Shot], but [Terminal Velocity] really improves the range.

I love the [Kuva Tonkor], but that's fire ... wait ... fire ... wait.
This is fire, fire, fire. :)
