I am not sure exactly how spending fatigue works. I know it can be used to gain movement, however when can that be done?
Example: I move my entire movement and attack a monster that totals 2 actions, can I now spend fatigue to move further? Or must fatigue be spent before using both actions that the heroes have?
Another example: I have 5 stamina with no fatigue. I spend 3 to move to a monster and attack. I want to move and attack another monster, may I spend my 2 more fatigue to move again? Or do I have to spend all the fatigue I want at once?
-Before any action -After any action -During a move action (because move actions can be interrupted, even by other actions.)
You can also spend those movement points at any of those times (you do not have to spend them immediately- that is, you can suffer a fatigue to gain one MP at the beginning of your turn, then attack something, then spend that MP.)
