When the command is inputted, the Hero will go into a thinking pose, and the player will be given a random selection of four spells from Hero's spell pool to choose from, with a total of 21 possible spells. While this list is open, Hero cannot move unless he shields or jumps, which will cancel the move altogether. The spells available are chosen upon inputting the move, and if the player does not see a spell they wish to use at the time, they can shield and immediately cancel the spell selection, and then input the special again to get another random selection of four spells. If the player holds towards the other direction upon selection, Hero will immediately turn around upon executing the move. Spells cannot appear twice in a row.
MP refilling is paused while the menu is open. Additionally, the Hero can only have the menu out for a certain amount of time.
