I can read the rune states from the memory, but I only get one byte value.
If all my runes are ready, it's value is 255. If my first blood rune is on cooldown, it's 254 (255-1). If my first blood rune is ready, but my second is on cooldown, it's 253 (255-2). If both of them are on cooldown, it's 252 (255-1-2). And so on with the other runes. How can I figure out, if my n. rune is ready?
