Stilts Corruption Affects ALL Actions
According to the corruption description of the stilts corruption, your "base movement cost" should be reduced to 750; however, looking at the energy calculator, it becomes immediately clear that this corruption affects all actions, not just movement.
Either the corruption label should be changed to "base action cost", the same as stiff muscles, or it should only affect movement. Personally, I think the latter is probably more thematically appropriate for what the corruption is supposed to do.
