狙击

狙击 is a keyword found on several item modifiers, on monster as well as Ascendancy passive skill of the same name.

机制

As the projectile begins to move from its point of origin, the attack gains more damage, capped at 60% more damage. It is important to note that damage scaling is done with respect to the total distance the projectile has travelled, not its current distance from the point of origin. If the projectile changes direction□as is the case with 灵体投掷□distance travelled continues to increase as the projectile returns to its point of origin.

According to 3.13 patch note:

相互作用

零点射击

零点射击 and Far Shot are multiplicative together (since they are more/less multipliers), and thus helps counteract the damage falloff at distance.

长射

长射 functions similar to Far Shot, but instead offers increased Damage instead of more Damage.

Due to the additive Nature of "increased" modifiers, making a general Statement on it's overall benefits is impossible, as every Build has different Amounts of "increased" Modifiers.

If you take Far Shot due to wanting to deal better with Enemies at Range, then Longshot certainly is a good choice as well.
