PC on Idol

I was doing thunderhead keep and found a shiverpeak key, as well as a shiverpeak chest...so i was wondering how much this idol was worth.

Idol (requires 10 blood magic)
+12 energy
Halves the recharge of Curses spells (chance 20%)

Gimme A B
Gimme A U
Gimme A M
Gimme A P

Wats That Spell>>>>>>>>bump!!

....bump?

Perhaps 1-3k since its not req curses and its only single modded.
