Ever wanted your flame thrower's initial hit to not just burn the guy you aimed at, but his entire squad too? This is the build for you!

If you aren't using the Vigilante mods on your Sentinel's weapon, you can swap [Vigilante Supplies] in for Primed Rifle Ammo Mutation for a slight bump in your crits.

Primed Firestorm can be swapped out for any of the following:

• Primed Shred/Speed Trigger (to get close to the fire-rate/DPS of the top ranked build's use of Vile Acceleration)
• Any Primed Bane (if you swing that way)
• Sinister Reach (should really be an exilus mod)
• Combustion Beam (great for laughs/meme-ing in low level missions)

If you want to save a couple of forma, and don't have ammo issues, you can skip the exilus mod slot entirely and leave one of the crit mods unforma'd.
