Sand Snare

( Sandstorm, p. 52)

[General]

When you knock your foes into the sand, they have a hard time regaining their feet.

Prerequisite

Combat Expertise (PH) , Improved Trip (PH) ,

Benefit

If you successfully trip an opponent in any area of ash, dust, loose earth, or sand that is at least 1 inch deep, that opponent must take a fullround action to stand during the round after being tripped. Following that round, the target can get to his feet with a move action (as normal). The opponent still provokes attacks of opportunity while attempting to stand, as normal
