The Spellstaff lists, among other benefits, generating "+1 Mana per Turn"
It does not specify whether this is per combat turn or turn on the strategic map, but in either case, having the item equipped has no effect. Mana does not generate when the staff is equipped during combat, and there is no difference in my mana generation (from my shards and whatnot) whether I have the staff equipped or not on the strategic map. :/ Am I missing something, or is the mana generation on the staff not working?
