Gavin Irby, Lead Raid Designer, announced a challenge mode for Destiny's King's Fall Raid. With this update, every week a boss will offer a new challenge that will only appear when you select them. These challenges will display next to a skull, and apply to both Normal and Hard Raids.

Each boss’s challenge requires that you defeat them in a very specific manner. How, exactly? We’re going to leave that up to you to discover (but apologies in advance to those that run the single-pool strat for Golgoroth).
