I purchased this cosmetic recently but the staff cosmectic only shows up as being available on my Druid and not my Sorceror. The sword cosmetic shows up fine for both. Please fix this.
Druid and scor staffs are not shareable. Nor have they ever been shareable.
I understand that items are not shareable. We are taking about a cosmetic/skin. Weapon cosmetics carry across different classes from my previous experience in purchasing other packs ?
No, just the “class limited” weapons are class bound. You can’t use any bow skin for your barbarian, totems for rogue, etc…
Sorry, I am probably being a bit slow here /am rather confused.
I can use a necro sword cosmetic on a sword for my rogue. This I have done.
I had therefore thought I would be able to use a druid staff cosmectic on a staff for my sorceror ?
No you’re not slow. that’s me 
Uli was sure druids dont use staves. I better play one before talking.
Cosmetics are “slot bound” and you can’t apply a cosmetic from a 2h staff to a 1h staff
Does your sorcerer bear a 2h staff or a staff/focus ?
