PC Q11 DF Astral Staff

I was wondering what this staff would go for:

Swift Astral Staff of Deathbane (Gold)
Halves Skill Recharge of spells (20%)
Enery +10
Fire Dmg: 11-22 (Requires 11 Divine Favour)
Halves Casting time of spells (9%)
Inscription: "Dance with death"
Damage +15% while in a stance
Dmg +19% Vs. Undead

Ignoring the fail mods, what'd it be worth clean? Or if I modded it?

Also wondering what a Q9 Sephis sword (Inscribable + Gold) is worth?
