That is the same reply I got from one of my friends. -laughs- The trade off should be something you would want to do multiple times, otherwise, yes the effect would just be an ability. As a 0 action, you could only do it 5 times. So if you would reduce your Wp by 1 to gain Casting Expert for one turn? Would you trade 1 Wp for Armor +1? It should be something that you would want to take. The upgrade could only be taken for a limited time, like 1 week out of a 6 week league. You did post some good ideas.
