For skills which do not target an enemy, is there any way to tell which party members they affect, other than by selecting them in battle? There doesn't seem to be any way to tell except on healing spells, which specify "Heal" for a single target and "Heal Party" for the entire party.
If there isn't a method in-game, is there a list somewhere online?
Edit: the reason I want to know this is that an ability which affects the entire party is in effect up to 4 times more powerful than its base stats. Not knowing this in advance when choosing or upgrading skills means trying to compare potentially incomparable skills.
