Flawless

Flawless is a partisan-type melee weapon which can deal high critical damage for infinite periods of time, assuming the player doesn't get hit. As soon as one takes damage, the DPS of this weapon becomes much lower, becoming one of the weaker melee weapons. Therefore this weapon can be considered high risk/high reward, especially against Elites and Bosses.

Trivia

 * Flawless shares its in-game model with the War Spear, and the Impaler. Of the three weapons, the icon used for Flawless resembles the model the most. This is ironic, considering it is a halberd, and not a spear. Flawless is even referred to as the Perfect Halberd internally.
