Telesto (Fusion Rifle)
No matter how hard you try to deny it, you just can’t knock a good fusion rifle. Those weapons are absolute beasts. Sure, they take a bit of getting used to due to their different charge rates, stability, handling, and other stats, but all of them are weapons that bring fear to enemies. Telesto takes it a step further by adding insult to injury as you send your Destiny: The Taken King opponents scurrying to their friends, only to take them down in a glorious explosion of purple light.
Unplanned Reprieve and Harbinger’s Spark make this exotic fusion rifle a thorn in the side of packs of enemies. Charge it up and let it rip to attach void clusters to enemies and walls. Said clusters then explode, dealing massive damage to your target and anything around them. If you land a multikill, you get to watch beautiful Orbs of Light fall from your victims. You also get a boost to your sprint which lets you make your way to your next group of victims that much quicker.
It may not have the best charge time, but its ability to absolutely wreck the opposition in Destiny: The Taken King is definitely worth writing home about.
