<sigh> I didn't realise how many rules holes there were in Complete Warrior until I looked closely....
The Giantbane [tactical] feat from Complete Warrior (p111) enables 3 tactical maneuvers: Duck Underneath; Death from Below; and Climb Aboard.
1. Does Duck Underneath (free action) provoke AOOs as normal from the opponent ducked under or from other opponents that threaten relevant squares you move through?
2. Is the resulting movement from Duck Underneath made at normal speed, or at the half speed associated with the Tumble skill (unless using accelerated tumbling)?
3. Is the attack from Death from Below a bonus attack? Or simply the attack you would have normally been entitled to [move plus standard action], but with the flat-footed and +4 attack bonus?
