How to use packet sniffing in F/GO

This method allows you to know the drops you'll get as soon as you enter a battle,
allowing you to surrender and start it again until you get a drop you want.
You'll still spend AP, but the farming itself will be faster. Useful especially when
reset-farming unrepeatable quests with high drop rates.

Update: Though this guide refers to ProxyCap, there's no crack for it, so it's
recommended that you get proxifier and adapt the instructions to it.

> I'm using BlueStacks so I'll assume you do too.

> First configure ProxyCap like this: http://www.proxycap.com/bluestacks.html

> Since we use 127.0.0.1:8080 on ProxyCap, we need to use the same IP and Port on Burp.
> Go to Proxy > Options and configure it like this: http://imgur.com/X6Yf7Gc.png
> Go to the Intercept tab and turn it off.

> If you get stuck at the login screen (connection error cancel - retry message),
> add 23.102.76.23 and 80 port to SSL Pass Through. This is the IP of their logging
> server (you can check it on Proxy > HTTP History in case it's different for you),
> so it should let you login fine now. I'm not an expert on this so there might be
> another way to fix this, but this is how it worked for me.
> Using proxycap, you only need http connection (port 80). Don't set 443 unless you
> install certificate.

> Now go to Extender > Extensions. Load the plugin and keep the plugin window open.

> Here's a link to the original plugin: https://www.mediafire.com/?u58d1e1tcx4d25r

> When you load a fight it'll give you a list of what you're gonna drop. It's updated up
> to the halloween event, but you can check http://fategrandorder.wikia.com/wiki/Drop_Infos
> for new item IDs.

Troubleshooting:
> Have you restarted?
> Have you done the Burp config yet?
> Have you restarted Burp upon configuring for the first time?
> Made sure that Internet Options is set to use the 127.0.0.1 proxy?
