Since a lot of the choices so far seem to include +Str/Weapons, will probably go with a magical user. Was thinking Death or Devil for either ailment or curse related shenanigans - I've got an idea for a character for either one. Curious about the effects of luck as well (yay gambling) so Fortune is also intriguing. 

Though, just to be sure, what does this part mean? Does it mean that for example... for Agi, instead of spending 5 SP, they may choose to spend 1 MF or 1 HP instead? 

[quote]may cast magic spells for the MF/HP equivalent to the tier instead of SP [/quote]

Anyone planning on having heal (and/or buff) stuff btw? Since Chariot, Death, Devil and Fortune cannot use heals.
