A misty vapor arises around you. It is stationary. The vapor obscures all sight, including darkvision, beyond 5 feet. A creature 5 feet away has concealment (attacks have a 20% miss chance). Creatures farther away have total concealment (50% miss chance, and the attacker cannot use sight to locate the target).
The way I see this, it can mean one of two things. Which of the following is correct?
1) Adjacent targets attack each other fine. A target more than 5 feet away (one empty square between them of fog) has 20% concealment. Targets further away have total concealment.
or
2) Adjacent targets have 20% concealment. Any targets with a full square of fog between them have total concealment.
2. it even explain that all sight beyond 5 ft is obscured -which is then set in numbers of the 50% miss chance at 10+ feat away.
Think of it this way: a target 0 feet away is in your square.
That was my thinking too but I've always had that nagging secondary thought about whether 5' away is a measured distance from square edge. I'm seeing a lot of fogs used lately in games so I wanted to be sure.
Thanks for the input you two.
Here is a related question: what happens if two combatants are adjacent but only one is in the fog?
1. The one outside the fog gets concealment against the one in the fog. Justification: there is no exception for asymmetry in the spell description.
2. The one outside the fog does not get concealment. Justification: concealment rules explicitly specify attacker and defender.
To determine whether your target has concealment 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 provides concealment, the target has concealment.
If you choose one of the corners in your square that is at the edge of the cloud, the lines to all of your opponent's square do not pass through any square or border that provides concealment.
However, two of the lines drawn from your opponent to your square will pass through the obscured square and thus you have concealment.
When making a melee attack against an adjacent target, your target has concealment if his space is entirely within an effect that grants concealment. When making a melee attack against a target that isn’t adjacent to you, use the rules for determining concealment from ranged attacks.
I can choose the corner on the outside edge, and all four corners of my opponent's square are clear. My opponent cannot do the same, since the back two corners of my square are in fog.
This means that when I attack from inside the edge of a cloud, I have NO Miss Chance against my opponent outside, while the opponent DOES HAVE miss chance against me.
