Clearly the BiS Wand is the one off Azuregos but it’s pretty unlikely I’ll ever see it so let’s just exclude that one. I’m curious what wand it better; Wand of Biting Cold from AV or Bonecreeper Stylus from Scholomance.
Thanks you for your input.
If you’re running BWL. It might be helpful to have a shadow and nature wand too.
I play a warlock and carry 3 wands for dealing other schools of damage in BWL to the chromatics
Oblivion’s Touch
Yes. I run with three as well. 
Av wand has been just fine for me
