I lost the horn of the tritons to offhand disarm, and then it was given to some lowbie bard. Since then I was using the twisting horns of valor or blue dragon horn.

I was epic preferred, but I also used tragic very often when I felt like sleep + maledict was the way to go. Tragic is also vastly superior for PvE.

The battaglia edge is awesome when it works but certain people are unaffected by it. Btw, it's apparently a nonmagical version of muscular lethargy spell, and that spell got buffed recently - instead of one weakened attack, they may hit you for scratches for several rounds, especially if their saves are bad. And of course that's in addition to the usual battaglia effects.

Btw, preferred rep only gives you +1 level in songs. Edge choice is what really makes it significant. I would like to try tragic preferred sometime.
