Description:
Sing is a useful and yet mediocre command. Normally, Sing casts two useful spells (Sleep and Charm) which can be reproduced with Edward's Harp attacks. It also casts one pathetic spell that's mildly useful (Mute) that hurts the useful spells. In the worst case, it casts no spell… which is a wasteful option. Of course, it's also worth noting that the "hidden" Frog Song spell is sung while Edward's a Toad.
This patch is meant to document and change the spells that Sing can cast to make it a more useful command. Mute has been replaced with Stop and the empty spell is replaced with Hold.
Note: Sing's effectiveness is dependent on the original spell's properties and the target's resistances. Increasing Wisdom (for Stop and Sleep) and Will Power (for Hold and Charm) will ensure they will become more effective. This behavior is applicable to FF4A's Chant command as well.
