| To handle the slow and fast spells, the game uses a speed modifier during battle. Initially this value starts at 16, and can range between 12, and 32. Any ATB delay is multiplied by speed mod/16, rounded down. This means if someone has a delay of 5, and their speed mod is 32, it would now take 10 atb ticks to process. \\ | To handle the slow and fast spells, the game uses a speed modifier during battle.

| - | One way to artificially slow down the game is to try running during a fight you can't run from. This will cause a message to pop up, which halts the atb from advancing until the message goes away. This can give you a little bit more time to get into your menus. Typically any fight that has monsters lower level level 97 will let you run away the first atb tick you press the buttons. If the fight is marked as one you can't run away, the can't run message will display, freezing the atb for 1-2 seconds. | + | One way to artificially slow down the game is to try running during a fight you can't run from.
