Starting a new character is annoying, everyone knows that, but I guess you have to when you’ve got 17 SP into Energy Bolt (don’t ask).
Making my second cleric, I decided to go on a skill path in which I would get the most MP possible. In short it means you put your first SP into Improving MP Recovery other than Energy Bolt. It continues like this until you max out Improving Max MP. 5 levels til Energy Bolt.
