The "Cabal" Hero (Wizard) has the trait: ATTACK +1 for each Spell you play.
The Card Glossary entry for "Cabal" says: In order for a Spell to be considered "played", you must have revealed and used its effects in the current turn.
The "Bluefire Staff" Weapon has this Dungeon Effect:
DUNGEON: If Bluefire Staff is equipped to a Cleric or Wizard, you may reuse a Spell card you have already used this turn. If you do, destroy that Spell at the end of the turn.
If I had a Fireball (or some other spell) in my hand and activated the above effect of the Bluefire Staff (yes, it is equipped to the Cabal), would my Wizard then receive an
ATTACK +1 bonus or an ATTACK +2 bonus?
