[OOC] Return to the Rusty Rat

[Lugar]

Fighting Defensively as a Standard Action: You can choose to fight defensively when attacking. If you do so, you take a –4 penalty on all attacks in a round to gain a +2 dodge bonus to AC for the same round. This bonus stacks with the AC bonus granted by the Combat Expertise feat (page 92).

I think a move action is fair for very specific information, like noticing details, but a quick look around to get general information only takes a second.
