True to its name, Predator Bows are a class of ranged weapons in Assassin's Creed Valhalla that offers a way for Eivor Wolf-Kissed to eliminate targets from further away than any other armament. They lack some of the features that appear on its sister weapon classes, such as the versatility of Hunting Bows as well as the raw speed and power of Light Bows, however, they make up for this by granting excellent sniping potential on all kinds of targets.
There are a few ways to use a Predator Bow, though, the best method is to stay far away from one's target in order to line up shots properly. Aiming for weak points, like the heads of enemies, is usually a good idea for ranged assaults, and is especially worthwhile when using this weapon class, for bows of this breed get the most bonus damage for hitting weak points out of all 3 types of ranged weapons.
While You Attack, Stay Back!
The only way to fire with a Predator Bow is to aim through the narrow scope-like attachment, which helps the player aim true but also blocks a lot of visibility for anything in mid and close range. This means that taking on anything too nearby will be incredibly tedious and awkward. This is a job for a Light Bow, or, better yet, any melee weapon. It is highly recommended not to use a Predator Bow from this distance.
With that said, if one is sniping at foes and one (or more) of them detect Eivor, they will likely return fire or come barreling towards the player with teeth or blades bared. In such an event, while it is imperative to put away the bow and pull out close-quarters armaments, this could be a prime time to get one last, easy headshot before the foe gets too close. This would soften them up for the imminent conflict or possibly even outright kill them; either of which would be convenient.
Patience & Timing Are Key
As one would expect, it's infinitely easier to line up headshots for significantly more damage while the target is unaware of Eivor's presence. Using cover is a great option, as the camouflage provided by many shrubs and low walls will grant the player quick and easy sniping spots at ground level.
However, getting higher up for a bird's eye view is recommended in every situation where the player will want to use a Predator Bow, as added height grants better visibility over a greater area. It may take a minute or two to get into a solid position, but this will be time well spent, as in addition to helping one's offensive tactics, it will make enemies take longer to get within melee range. This is especially true when hunting beasts; a properly chosen firing spot can make combat trivial, as wild animals have no means to scale a hillside cliff or a vertically inclined bit of Roman ruins.
