2 Topics of questions
Topic 1) I'm working on a new character concept with at least 23 bard levels with Practiced Spellcaster (Bard) for what I believe would be a total of CL27, and I'm looking for help understanding the significance of the CL27 threshold that a lot of people recommend?
Is CL27 the magic number (no pun intended) to become un-dispellable by NPCs or something? What about dispels from PCs?
The more specific you can get with details and examples, the better for me to understand
Topic 2) the TLK Performer -- I've been experimenting with the instruments with a non-bard character, and they're pretty fun and neat, but I'm guessing a lot of features are reserved for proper bards with appropriate Perform skill levels?
In particular, these features seem to be unavailable (for a non-bard/no-Perform-skill character): saving songs with tracks from multiple instruments etc, having lyrics associated with instrumental tracks, or inscribing songs onto paper for trading, etc.
I'm wondering if these features are disabled in general, or having a proper Bard with high Perform skills would make these features available?
Thanks for any insight!
