Destiny 2: Malfeasance Deals More Damage to Targets Affected by Witherhoard

With Destiny 2 being such a vast game that features all sorts of different weapons and abilities, it's not uncommon for some interactions to be unintended behavior and cause strange bugs. Telesto is the prime example of this, as the gun itself has plenty of different interactions with itself, the surface or enemy its blots are spread onto, how it is affected by collision, and many others. This often causes weird and dangerous interactions that can result in game-breaking issues, like how Telesto bolts could be stacked and destroyed with a Stasis or Solar melee ability to generate infinite Orbs of Power when Thermoclastic Blooming was equipped.
