History of Burst Guard

Burst Guard is a guard perk on Swords. Its in-game description reads "Sword Guard has low efficiency and high defense." It is one of the two guard options on Honor's Edge, the other being Enduring Guard, which Destinypedia describes as the sustained-blocking option; Burst Guard is the defensive-play option. The sword's blade perks are Tempered Edge and Jagged Edge.

Honor's Edge also has the Adaptive Frame intrinsic and the trait En Garde (bonus damage on quick attacks right after switching to the sword).
