Du kan ladda när som helst du vill att du får se din ansträngning och det finns en praktiskt 10 meter lång rak bana mellan dig två.
D20SRD säger:
You must move before your attack, not after. You must move at least 10 feet (2 squares) and may move up to double your speed directly toward the designated opponent.
You must have a clear path toward the opponent, and nothing can hinder your movement (such as difficult terrain or obstacles). Here’s what it means to have a clear path. First, you must move to the closest space from which you can attack the opponent. (If this space is occupied or otherwise blocked, you can’t charge.) Second, if any line from your starting space to the ending space passes through a square that blocks movement, slows movement, or contains a creature (even an ally), you can’t charge. (Helpless creatures don’t stop a charge.)
If you don’t have line of sight to the opponent at the start of your turn, you can’t charge that opponent.
Om avgiften står det också på Fotflottfesten :
Without this feat, you can run or charge only in a straight line.
