[b]TLDR: No Feelings Scout Rifle- Collective Demolition+Explosive Payload[/b] After watching a handful of creator content on YT I came across an interesting DPS Loadout involving Arc [b]Armamentarium[/b] and [b]Apex Predator[/b] utilizing [b]Collective Demolition[/b]. As a fan and regular enjoyer of [b]Armamentarium[/b], I quickly tried the build (despite lacking the Coda Armor). It performed incredibly well, but the real takeaway was that [b]Collective Demolition[/b] is incredibly potent. So I hopped over to [i]Light GG[/i] to find out what else has it...... The perk is mostly prevalent in the 4th column, which is a disappointment overall. However, I found a solid sleeper with it in the 3rd column that performs well in roaming content, that being the [i]Black Armory's[/i] [b]No Feelings[/b]. The 180 Scout is Arc, having intrinsic Anti-Barrier and slew of the usual Arc synergy perks. While my [b]Voltshot+Gear Shift[/b] roll is fun and more versatile, I found that [b]Collective Demolition+Explosive Payload[/b] to be the pinnacle of perks in regards to Grenade Spam. The double hit of E.P. chunks grenade energy back in an unfathomable manner, as it registers 2 hits, granting a whopping 6.7% grenade energy per shot. With +100 Grenade, it only took 10-12 shots for a full refund, and that's without the Coda Armor. Mind you this was also with [i]Ionic Traces[/i] flying back to me via [b]Touch of Thunder[/b]. But those simply filled the gap regarding what [b]Collective Demo[/b] wasn't returning. Any build that can spam [b]Ionic Traces[/b] will benefit from this weapon. The origin perk gives great synergy and pairings with[b] Izzy & Bellowing Giant/Stryker's Sure Hand[/b] for some "free" damage.
