Is the archeology stuff bound to account or to battle.net-account

[RSM72]

Is the archeology stuff bound to account or to battle.net-account? Thus should I be leveling archeology on one toon per account or just on one toon at all.

Epics are battle.net account bound, but you can't get them more than once per toon.

Epics are battle.net account bound, but you can't get them more than once per toon.

Important note, this is true for epic gear only (whatever level), Pendant of the Scarab Storm (http://www.wowhead.com/spell=92145) excepted!
