New and Improved Guide to Ranged Cover

Postby benrady » Wed Nov 19, 2014 11:16 pm

Cover is pretty easy to understand when it comes to melee attacks. If you're attacking around a corner, your target gets a +4 bonus to AC. For ranged attacks, the rules are a bit more complicated. If you're going to be doing a lot of ranged attacks, it's important to understand these rules.

(RAW as quoted text)

Total Cover

If you don't have line of effect to your target (that is, you cannot draw any line from your square to your target's square without crossing a solid barrier), he is considered to have total cover from you. You can't make an attack against a target that has total cover.


In this example, we have an archer who wants to attack a Zombie, but the Zombie has total cover from a square earthen column.

Image

Cover

To determine whether your target has cover from your ranged attack, choose a corner of your square. If any line from this corner to any corner of the target's square passes through a square or border that blocks line of effect or provides cover, or through a square occupied by a creature, the target has cover (+4 to AC).


If the archer takes a 5 foot step to the southeast, he exposes two corners of the zombie's square. He can now attack, but the zombie gets a +4 bonus to AC due to the cover provided by the earthen column.

Image

Partial Cover

If a creature has cover, but more than half the creature is visible, its cover bonus is reduced to a +2 to AC and a +1 bonus on Reflex saving throws. This partial cover is subject to the GM's discretion.


If the Archer moves 10 feet south, he can now see 3 of the 4 corners of the Zombie's square, meaning that more than half of the zombie is visible. Assuming the GM agrees, the zombie now has partial cover, reducing his AC bonus from +4 to +2.

Image

And if the Archer moves 10 feet to the east, he now has a clear shot at the zombie (no cover bonus to AC).

Image

The partial cover rule is interesting in that, unlike the other rules for cover, it doesn't make any assertions about squares, only how much of the creature is visible. This means it can also be applied in three dimensions.

Soft Cover

Creatures, even your enemies, can provide you with cover against ranged attacks, giving you a +4 bonus to AC. However, such soft cover provides no bonus on Reflex saves, nor does soft cover allow you to make a Stealth check.


In this example, the archer is joined by a Barbarian, who is also attacking the zombie.

Image

The Total Cover rule states that it requires a solid barrier, so note that even though all four corners of the zombie are obscured by the barbarian, the archer can still make at attack. There is no difference in the AC bonus (+4 in both cases), whether the archer is firing straight on or at an angle.

Big Creatures and Cover

Given that you have to be able to see more than half of a creature to reduce that creature's cover bonus to partial, it's possible for two medium creatures to provide soft cover to a large creature.

Image

Unlike previous the example with the zombie, if the archer makes a 5 foot step south, he exposes enough of the large creature to see more than 50% and reduce the cover bonus to partial.

Image

Or, if only one medium creature is present, the archer can see more than 50% of the creature, and so only partial cover applies.
