The wielder readies the greatbow, entering a prepared firing stance and holding steady; moving will cancel this stance. The player can then nock the greatarrow of their choice and release it when ready. The arrow will gain increased travel distance (and with it damage fall-off) and inflict 12% more damage, and will penetrate any enemies it hits, allowing it to damage multiple foes with a single shot.
If used without the required FP, the arrows will deal less damage than regular shots and inflict reduced knockback but will still penetrate.
As the skill requires the player to stand still prior to even readying an arrow, it can be difficult to use against mobile targets. However, the increased damage and penetrating nature of the shot makes it extremely useful for dealing with crowds of enemies, particularly if they can be funneled through a single approach, such as down a narrow hallway.
Other players will generally not stand around waiting to be shot with a greatbow, and can easily dodge the shots that they can see coming, so the primary use of this skill is through ambushes with the Obscuring Ring. This skill allows invaders to get a powerful first strike in on unwary hosts and summoned phantoms, helping to narrow their Estus advantage before properly engaging them. Keep in mind that it is incapable of dealing significant damage through raised shields, so against wary parties it may be useful to try to strike them from the sides or behind.
