Q402

How does mounted combat work? First i have a human on a warhorse, second I have a halfling on a wolf. I know they both have to make ride checks but when do they make the checks? Also what decides the DC of the check? Another thing do the rider and the ride have different initiatives or do i roll only one for both. If different who do I follow when moving and attacking? I know the horse doesn't attack but a wolf can, so will both the rider and the wolf attack or one only?

Q403

How does power attack work? I know it takes the weapon strength bonus and turns it into damage but I'm not sure. If I have a strength mod of +4 and the weapon gives a strength bonus of 1.5 do I just add six to my damage? Please clarify.
