Frightened
A frightened creature flees from the source of its fear as best it can. If unable to flee, it may fight. A frightened creature takes a –2 penalty on all attack rolls, saving throws, skill checks, and ability checks. A frightened creature can use special abilities, including spells, to flee; indeed, the creature must use such means if they are the only way to escape.
Frightened is like shaken, except that the creature must flee if possible. Panicked is a more extreme state of fear.
Panicked
A panicked creature must drop anything it holds and flee at top speed from the source of its fear, as well as any other dangers it encounters, along a random path. It can’t take any other actions. In addition, the creature takes a –2 penalty on all saving throws, skill checks, and ability checks. If cornered, a panicked creature cowers and does not attack, typically using the total defense action in combat. A panicked creature can use special abilities, including spells, to flee; indeed, the creature must use such means if they are the only way to escape.
Panicked is a more extreme state of fear than shaken or frightened.
A couple of questions,
1. What constitutes cornered? If there is a diagonal between two creatures is that considered cornered?
2. And isn’t bull rush or overrun viable options as long it isn’t the source of the fear? If so, does that apply to everyone regardless how good they are at a combat maneuver?
3. And if they move out of line of sight from their source of fear can they do any other actions?
