mv 'movement points'
Movement points are expended as you move from one place to the next. Walking through difficult terrain will cost more mv, and flying reduces the number of mv lost. When your mv is lower than what is needed to walk around in the region you're in, you will be unable to move. Using the "recall" ability or casting "word of recall" will cost you a portion of your movement. Movement points regenerate over time, quicker if SITting or RESTing, and even faster when SLEEPing. The HEALER can also be of assistance, or the "refresh" spell. Stances also use movement points, see <send>help stance for info. See help hp mana move calc for more details.
