I was looking at Freya's skill list the other day and noticed that there are simply a lot of skills that she has that I never use or only used until a certain point. Take Lancer for instance. I never use that beyond disc two. Six Dragons I never bother to take the risk with. I think a lot of Amarant's skills fall into the same category in that I simply never found a particular use for them.
Naturally some of the more unorthodox spells are fairly easy to find a use for. Vivi's Doomsday, for instance, can be ridiculously great if you have Dark elemental absorbing equipment because then you're healing yourself as well as damaging the enemies. Likewise Reis' Wind is one of the most useful skills to have in a boss fight at the beginning of the game. Particularly if you don't happen to have a white magic user in your party.
So basically, what skills don't you use? And more importantly, have you ever found a cunning use for the less-used skills. Naturally we all use the elemental magic spells, but things like Six Dragons, Lucky Seven, Steiner's various Breaks and Slashes and Amarant's Curse tend are ones I tend to neglect. Any interesting strategies to share while we're at it?
