| - | This is a pretty complicated topic, but the gist of this is, if more then 1 timer is expired on an atb tick, the game handles only 1 of the timers, then advances to the next atb tick.

| Its also interesting to look at how you get your turn, first you have to be added to the character queue, then next atb tick the menu can pop up, if you are fast enough, you can input an action that atb (basically BS 6 only), and finally the the action you input gets added to the timer system at the end of the next atb cycle. This means there is always at least 3 atb ticks of delay from when a character gets their turn, and your action goes off, so especially at the start of battles, this can make it difficult to perform actions such as throwing a star-veil against wyvern.\\ | Its also interesting to look at how you get your turn, first you have to be added to the character queue, then next atb tick the menu can pop up, if you are fast enough, you can input an action that atb (basically BS 6 only), and finally the the action you input gets added to the timer system at the end of the next atb cycle.

| + | ==== Speed Modifier ==== | ||
| + | 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. \\ | ||
| + | \\ | ||
| + | Slow increases the speed mod by 8, and silkweb increases it by 16. Fast decreases it by 3, and hermes is -8. Normally using fast isn't worth it, as you can only reduce delay by 3/4, but sometimes it can be worth it. Notably, max application of fast will take meteo cast time from 20 atb ticks, to 15. On the other hand, it can be useful in berserk scenerios, as RA 2 will become RA 1 with just 1 cast of fast. In the zeromus fight this is less useful, as blackhole resets the speed mod on the party (but not zeromus). \\ | ||
