A staple of RPGs, your characters can learn attacks or skills such as Instant Death, Poison, Confusion, Paralyze, Silence, and Petrify that at first glance seem incredibly useful. However, in reality these spells are usually anything but useful, for any of the following reasons:
1. Bosses, sub-bosses, and other types of enemies that actually pose a threat to the player are always extremely resistant or immune to such attacks. If they weren't, the Useless Useful Spell would make things far too easy, and may even be a form of Disc One Nuke.
2. Common enemies that the attacks are effective against can easily be disposed of by use of normal attacks, which means there's no sense in wasting time and magic power on fancy maneuvers. Who's going to waste 36MP to cast Instant Death on the local harmless Underground Monkey? Or wait for Poison to kill your opponent when often other methods do damage much faster?
3. They may simply have a very low success rate in the first place.
4. They are replaced by spells that effectively do the same thing and more later on in the game, for example, any status healing spell can be replaced by a "heal-all" spell.
Of course, when any enemy possesses such spells, they will invariably be effective when used on you, unless you happen to be wearing a type of armor that protects against such attacks or status effects.
