Hail fello song brothers and sisters,

I was looking at the list of instruments and songs from the concert hall,
and I saw some info that concerdicted the song and instrument list from this
site. I was wondering if any of you have tested the following songs and
instruments, and know which site is correct.

song: Denon's Desparate Dirge, Lev 43, this site says damage is 311+(lev-43)*2
making MAX dame at Lev 50 only 325, and does not say anything about mana; CH
says it does 275 dam and requires 800mana?

Instrument: Mistmore battle drums: this site says +20%; CH says +25%

Instrument: Lute of the gypsy princes: this site says no effect; CH says +5%

Was just wondering if anyone can conferm which site is correct? I am only
Lev 22, with no unique instruments, so can not test them, but I am on
Bristlebane and if any of you High Lev Bards on Bristlebane can give me or help
me obtain the MM Drum and Princes Lute, I will be more then happy to both Pay
for the Item and Test them! HEHE HAHA *LOL*
