Hello, the third book of the series is prepared to be at a higher level than the systems described earlier. The systems described here appeal to players who have used the system before and have reached a certain level. If you have reached so far in the systems, we can say that you are now on the way to becoming a master.
Starting from the beginning level of the systems, it will be more useful to understand and implement the systems.
Along with the 39 systems described in this book, a total of 100 different systems are discussed and explained in this series.
