Insidious is an Arc pulse rifle and one of six new Legendary weapons players can hunt down within Destiny 2’s Vow of the Disciple raid. Despite an unexceptional first impression in the face of a new Exotic pulse rifle within the same raid, Insidious makes a case for itself through entirely unique perk rolls and the rare Aggressive Burst Frame it exists within. The four-round burst fire was most notorious on the now-sunset Blast Furnace pulse rifle, and Insidious nestles perfectly into the Blast Furnace-shaped hole in every Guardian’s heart.
While Insidious will excel best in PvP environments, its perk pool comes with a plethora of options for PvE as well. The level of choice available is what makes Insidious a great pulse rifle to farm, and the majority of potential rolls you can acquire will have some use cases even if it isn’t the god roll. Dragonfly and Demolitionist existing within Insidious’ first perk column plays a big part in this scenario, allowing any player to use Destiny 2’s strongest utility perks without sacrificing a damage-boosting perk in the second column.
