Boom Stick 💥

This is the most accurate shotgun in the game that functions much like a semi-auto rifle. Thus, deadly headshots are easy and only get easier with the Arcane, because it simultaneously increases your accuracy and headshot damage multiplier. All of the Galvanized mods and Arcane give an insane increase to damage output and status chance, such that you're guaranteed to hit hard and always proc the status effect.

Usage
Very little can survive a single shot from this gun. The Impact back damage is so hard and the status procs frequently and makes any survivors vulnerable to Mercy finishers. You should be expecting to execute a lot of Mercy kills as often as possible on anything that doesn't die quickly. Prepare your Parazon with [Blood For Ammo] + [Blood For Energy] + [Blood For Life] for sustainability in any mission. Alternatively, consider [Out Of Sight], [Malicious Code], or [Power Drain] where sustaining energy, health, or ammo is not needed. These later mods are great for intense fights like Steel Path Arbitration missions because they provide free crowd control or ability strength increases for your Warframe of choice. Mercy finishers provide you with a second or two of invulnerability during the assassination animation - this is advantageous to survival. Hence, the frequent execution of Mercy finishers provides you with incredible defensive and sustainable tactics enabled by this gun. You can easily kill the tough Bombards, Gunners, Nox, and Eximus enemies using this method.

Anti-air Priority 🎯
The corrosive and blast damage excel at destroying all drones/machines (Arbitration Shield Drones, Ospreys, [Regulators], etc). Prioritize these targets as your are ideally suited to take them down easily from any range.

Plus, it's really fun and satisfying!
