A lot of the cards refer to "your hero" what does this mean? For example the blademaster card for the field commander says "your field commander hero uses one additional battle dice in melee combat." Does this mean when the field commander is in the role of champion or leader an extra dice is rolled? so if a starting out field commander took the blademaster skill he would be rolling two dice in combat and if he was a leader with a green unit they would roll 3 dice, if he was with a blue 4 dice, with a red 5 dice?
So basically what I'm asking is does the term hero apply to both champions and leaders?
Also If a card has a lore cost can I use it multiple times on a single triggering action unless the card says otherwise? for example the cleric's chant card says "lore cost:2 enemy units attacking your cleric hero roll one less battle die in melee. this skill may not be used when an enemy is battling back. use before battle dice are rolled." So with this card could I pay 6 lore and reduce an enemy's attack by three dice?
