I would like to suggest a change, either:Anti-Magic Melody: At 5th level, a dissonant chord can use her Perform skill to negate magic. This works as Mordenkainen's Disjunctions with a cap equal to her bard level (no prestige classes count and this has a +25 max cap). This potent ability is quite exhausting to use as each time it is activated it uses four of her bardic music uses for the day.
- let Bard progressing prestige classes count toward this cap.
- let the Dissonant Chord PrC count toward the cap (at least).
Correct me if I'm wrong, but the ONLY way to maximize this feat is to build a Bard 25 / DS 5. And, the Mords itself strips 6 spells from the Breach List, then, makes a DC against all spells on the Target, at a maximum DC of 25 + 1d20 vs 11 + CL of Target.
Do either of my options sound reasonable? With the 25 cap, this Fear has a 15% chance to work against a CL 30 Target, however, ONLY if you make one build (the 25/5 split).
