Since bards are suppose to the musically inclined class, I figured that this skill would be kinda of useful or interesting. (as if they need anything else)

Rehearsal (gen 1) level 30

You performances are important to your success. Under this skill you can rehearse a particular song, making it easier to perform. You are limited to 2 or 3 songs.

With this skill, the cost of mana for these songs are reduced buy a randomized number. The affect of the skill last maybe 2-3 minutes depending on gen and intelligence.

what you think?

I don't see the point. I've never heard of a bard complain of a mana problem and if they do, that's because it comes with the territory. Also, it doesn't seem interesting to me at all.
