Probably one of the hardest bonuses in a mission: defeating Glint in The Dragon's Lair. The group had 6 of us dead at 1 point, but then after reviving, and eating candy canes (to wipe the death penalty) that someone brought, we tried again and finally defeated Glint. Post your glint ownage screenshots here!
