3 of the new PGL/MNK abilities confuse me. Are these new skills an simple enspell added to our normal attacks? Or do these skills simply make our attacks magical?

PGL Abl. 5: Converts your attacks into fire attacks and grants a bonus to attack power. Effect fades upon reuse. MP is continually consumed while effect is active.

The way PGL ability 5 explains this skill is what gets me confused. Why would we get an attack bonus if our attacks are suppose to be elemental now, I would like some clarification for this.
