For Athnul the monk:
"For your Melee combat check, you may recharge a card to add your Wisdom skill and the Bludgeoning trait."
Strength Melee: d6+2
Wisdom: d10
If I play a blessing, I get to add "a die", which would normally be another d6, since I'm using Strength: Melee. If I'm recharging a card to add my Wisdom skill as well, do I get to choose to add a d10 instead?
