I have discovered how to change variables using the "plus/minus sign" once you make a link, though, I ask is that how do you change the variable score if you use a item? Let's say you dodge an ogre's blow, but get nicked on the head so you lose 12 health. And then you use a sword against him. He dies. And his skeleton companion shoots an arrow at you.
Can I automatically change it as the page comes up? Like, if you use the item, the arrow hits you, there is no link, and the variable changes for health. How can I do that if the only option to change the page is to use an item?
