I'm trying to understand how using Acrobatics to avoid attacks of opportunity works.
The green dot is the creature that wants to move past its foe without provoking any attacks of opportunity. The red dot is the foe, and the blue dot is the square that the green creature wants to reach. The light-blue area is the foe's threatened area. Both the creature and the foe are medium size.
The red foe's threatened area includes its own space
A creature has to make an Acrobatics check for each threatened square it leaves
Entering an enemy's space provokes an AoO "should be considered" (IIRC) aside from moving out from a threatened square
Assuming every check is successful, how many Acrobatic checks does the creature need to get from the green to the blue square, through the foe at the red square?
