"You can’t move diagonally past a corner" : I didn't understand this


Rules Questions

Liberty's Edge

"You can’t move diagonally past a corner" says page 193 of the core rulebook, under the section "diagonals".

Can someone rephrase this in different words, and help me understand what this actually means?

I know it's possible to move diagonally in pathfinder and it counts as 1-2-1-2 (5ft-10ft-5ft-10ft so on..)

If there is a corner in your way you can't move diagnolly through it, you have to move in an L around it.

Consider the above very crude ASCII.

You have walked along a hall, and stopped just before a corner. This spot is marked as A. The square above is a wall, the square to your right (B) is the junction of the corner.

You cannot move diagonally from A to C because of the corner. You can go A B C, but this is not diagonal movement. If an obstruction was occupying B, say for example, a hostile creature, you cannot simply diagonal past them.

You can move diagonally past an enemy - explicitly.

What you can't do is move diagonally past a solid object that runs along that border - such as a wall. Basically look at what is in your way. if you can step over it (such as a pit) or it doesn't fully fill the space (a small tree) then you can move past it diagonally.

If, however, you are trying to step around a big impassable object that either fills the square or runs along that edge such as a really big tree or a building (or a 'designated exception' type creature that fills the entire space - such as a gelatinous cube) then that's a big no.

Ingeniously explained, I get it now. Thanks guys!

You may have to enlighten me. If there is a diagonal line of enemies, as drawn below, can you cross it freely (AoO's notwithstanding)? I thought not, but perhaps misunderstood.

For verisimilitude let's say they're gnolls.

Yep, per the above quote. Silly, isn't it?

If the gnolls are starting in this configuration, I'd suggest setting up the combat map such that everything is rotated 45 degrees so that this isn't a problem. Of course, if the scenario involves two diferent rows of creatures at a 45 degree angle with each other, you're out of luck. (Edit: Or houseruling that you can move diagonally past a creature but not two creatures...!)
