The descriptions are '.' in all versions I'm pretty sure. This isn't the English specific issue that the inability to use the abilities was.
Pavor Nocturnus seems to have a higher success rate if the target is asleep. It might also work more if the target is lower on HP, but I haven't really tested that. It also consumes TP, so it may or may not affect it
It's not too bad for a Ward, really. It's something you can use if someone has sleepga'd a bunch of monsters, to try to eliminate one of them quickly, without using a 2hour.
