I found a permanent event card that tells me to craft something. To do so I can lower the cost if I stand on a card with bamboo or stone resource but the terrain card that the permanent event is attached to does not have any resources. So, how can I lower the cost?
If I have cards crafted with the specific resource, can I use them to lower the cost of the action on the permanent event card?
I have never found any cards to put in my hand or craft that clearly provides me with resources?
