A 177: No, a Bloodstorm Blade does not get new maneuvers since it does not specifically say that it does. Personally, I've never understood why it's even in that book instead of a CW web enhancement or something.

Q 178: A character with 1 level in Abjurant Champion gains Extend Abjuration. Could that character apply the Extend Spell feat to an abjuration spell affected by said class feature, tripling (quadrupling?) the duration of the spell?
