Battlefield Overture help!

[pofoman456]

I've been doing some number crunching lately to see how high Battlefield Overture could get right now and I just want to make sure I did not miss any buffs or anything.

Playing Instrument Skill:+15 Music buff Effect
Demonic Gloomy Sunday:+22 Music buff Effect
Grandmaster Bard:+5 Music buff Effect
Yvona Prefix title:+8 Music buff Effect
Master of Battlefield Overture:+8 Music buff Effect
Harmony Enchant:+5 Music buff Effect
Music playing reforge level 20:+20 Music buff Effect
Musical Knowledge Inspiring Performance Effect level 10:+10 Music buff Effect

My math came out to 49.58% max Damage for a Max play

Is there anything else I am missing?

Encore enchant - 3
2 Solo enchants - 4

Total 7 buff from missing enchants

Derp, orchestra is duration.
