Help with Packet Sniffing

Can someone help me with this packet sniffing? I have a little experience with cheat engine, but this is a little bit different. I tried to change the values by using wpe pro but the problem is that there are a lot of the same values and I don't know which is the one I'm looking for, so it will be nice if someone could give me a tutorial or something.

I know how to record packets and have them pop up in a list on WPE PRO but I have no idea what to search for.

I know how to do it too, that's not a brain teaser -.-

So what packet am I looking for exactly? Do I look for the one that has the EXP number in it using the search with Ascii??

I am a bit lost lol.. Can someone give me a very quick summary, even if its only 4 words lol

I would suggest that whenever you want to locate a specific packet you do the "talking" approach. Each time you are about to do something, write something before (like typing in the console "start" and press enter), do what you want next and write something after (Like typing in the console "end" and press enter).
After that, locate the packets that contain the words "start" and "end", once they are found, the packets that you want are between those 2. The rest I still dont know how to work with.
