Baldur's Gate : The Sword Coast Chronicles : NWN2 Persistent World

The feat is good but the requirement is high.

Prerequisite: Character level 21, CHA 25, Perform 30, bardic music.

Some of the DC builds I linked had one unspent feat, you may feel free to add it there. I went for high charisma and should be able to get it. Not on the Blackguard though, not without giving up either Curse or Lingering Song.

I hadn't actually even looked at it. The skill requirement means you can only take it at level 27 and up. Thus it can be hard to free feats for it. Hmn... You could have Jarring with Extra Defense.

On the build I posted you could certainly take Epic Inspiration by dropping a Great Charisma, but the point was to get Song DC's as high as possible for the Storm of Vengeance song.

Ahhh okay. I wasn't aware how hard the requirements were to meet. Makes sense. It seems like a very powerful feat to have though.
