Just wondering, in 3.5, can you use the Charge action on an extra granted action, e.g. if an ally uses the Clarion Call (White Raven) manoeuvre to give you an extra move action? Normally, you can Charge only on a full-round action, unless you are restricted to a move action or a standard action only (in which case your Charge distance is up to your speed, rather than twice your speed) - would this qualify? What if you granted yourself the extra move action, using a Belt of Battle or the Quicksilver Motion manoeuvre?
I'm inclined to say 'yes' (after all, it would be quite cinematic to have a character charge in, cut a mook in half (full-round action), then continue the charge (extra move action, e.g. from Belt of Battle or Quicksilver Motion) and cut down the BBEG), but wanted to get some opinions on this first.
