Which version of a Nanodeck do I have to have equipped in order to use/cast the profession nano you get from the Alpha & Beta Matrix box? The “plain” Nanodeck from the Dustbrigade / Peacekeeper Constad quests? Or the “activated” Nanodeck? Or, the Stellar Nanodeck after being upgraded with a Star?
Any variant is fine; typically you’ll want to use the stellar nanodeck because it adds some nice bonuses, but until you have that, you can also wear the unupgraded or activated nanodeck.
On aoitems, you can see it on items by the Wear effect Set flag NanoFocusLevel &NanoDeck.
