Please explain what each technique and skill in Phantasy Star IV does

I find it very difficult to remember what each technique or skill does
just by looking at its name, so I've been playing with a PDF version of
the game's manual always open on my tablet. The thing is, not every
technique and skill is explained in the manual either, like Gryz's "Crash"
skill.
Can you provide a list of every technique and skill found in the game and
its effect?
Thanks.
