Question 1:
Vika's blacksmith power states
"When you would discard a weapon ([] or armor) for its power, you may recharge it ([] or another card of the same type in your discard pile) instead."
Just by reading the text, if you were to take the second check mark, it would read "When you discard a weapon ... for its power ... you may recharge another card of the same type in your discard pile instead." The naive reading of this would say that the recharging of another card of the same type replaces the original discard, so you have to discard nothing. I'm guessing that is not what it is going for and instead the power should read something like:
"When you would discard a weapon ([] or armor) for its power, you may recharge it instead ([] or discard it and recharge another card of the same type in your discard pile)."
Question 2:
In the blacksmith role there is another power that says
"[] When you would bury a weapon or armor, discard it instead"
Does this combine with her other power above so that if you were to bury a weapon ([] or armor) for its power, you can recharge it instead?
