+==Missile Weapon Accuracy==
+Missile weapons calculate accuracy in a different way that melee combat. Because of the distance, there are multiple factors that play into how accurate a shot will be.
-==Missile Weapon Accuracy==
+The abstracted formula for accuracy is:
+<math>\text{Accuracy Variance}= \text{Aim Variance} + \text{Weapon Variance} + \text{Flat Variance}</math>
+Where accuracy variance is the vector in degrees affecting the original trajectory. This means that the farther the projectile travels, the more this variance will affect its path.
+===Weapon Variance===
+Weapon variance is the accuracy attribute on all missile weapons. Counterintuitively, the numeric representation of accuracy has a greater number represent lower accuracy, where 0 accuracy means that it is a perfect shot. For easier calculation, each missile weapon on this wiki also includes the numeric accuracy.
+{| class="wikitable"
+!Accuracy
+!Numeric Version
+|-
+|Very High
+| 0
+|-
+| High
+| 1 to 4
+|-
+| Medium
+| 5 to 9
+|-
+| Low
+| 10 to 24
+|-
+| Very Low
+| ≥25
+|}
 ===Flat Variance===
-<math>\text{accuracy} = 2d20 - 21 - \text{AGI mod} - (\text{Missile accuracy} + \text{Bonus}) </math>
+<math>\text{Accuracy} = 2d20 - 21 - \text{AGI mod} - \text{Bonus} </math>
-The bonus in this formula is determined by:
+The bonus in this formula is a sum of different flags that depending on the attacker, weapon, and target effects:
-Bonus = 2 (if steady hands) +1 (if marked) + AimLevel(?) + 4 (if scoped) + 3 (if stablizer arm locks)
+{|class = "wikitable"
+!If:
+!Bonus
+|-
+|[[Steady Hands]]/[[Steady Hand]] with the respective weapon type
+| +2
+|-
+| Target is marked
+| +1
+|-
+| Weapon is [[Scoped]]
+| +4
+|-
+| [[Stabilizer arm locks]]
+| +3
+|}
+If {{Dice tooltip|2d20}} ended up above 25 (7.5%), the accuracy is subtracted instead.
-if 2d20 ended up above 25, num11 becomes -num11
+===Aim Variance===
+Aim variance is the flat variance added to the distance traveled.
-===Aim Variance===
+aim variance = flat variance + distance + Bonus + [weapon accuracy, -weapon accuracy]
-aim variance = flat variance + xdistance
+{|class = "wikitable"
-If you're running and not sling and run, add a number between -23 and 23
+!If:
-If you're flanked, add a number between -23 and 23
+!Bonus
-Add a number between -weapon accuracy and +weapon accuracy
+|-
+|Attacker is [[Sprinting]] and does not have [[Sling and Run]] (works with any missile weapon)
+| +(-23 to 23)
+|-
+| Attacker is flanked (surrounded by 2+ hostile creatures)
+| +(-23 to 23)
+|}
-The closer to 0 num 12 is, the better.
+==Projectile Hit==
+When the projectile actually hits the target, regular damage calculations occur. However, there is a -5 DV penalty. If the target has [[Swift Reflexes]], the penalty will not be inflicted. If the creature is immobile, the DV is set to a flat -100.
-Basically, shoot things close. Shoot things with scoped missile weapons, unless they're sniper rifles
-Shoot things when you're not sprinting or flanked.
-In theory, every +agility gives you an extra tile.
