Fate/Grand Order /fgog/ Packet Sniffing Guide

What is this?

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.

When should use this?

When farming unrepeatable quests with high drop rates (Halloween Gorilla/Party time Quests).
When you need an event CE drop but already cleared the shop or don't care about clearing it.
When farming rare materials on stages that don't drop anything else (Pages, Horsehoes, Gears, Jewels)

Sounds great, what do i need?

Proxifier: https://www.proxifier.com/download.htm
Burp: https://portswigger.net/burp/download.html
/fgog/ droplist burp extension: https://www.mediafire.com/?u58d1e1tcx4d25r

Note: This guide will use Andy as an example, but i assume the same method works with MEmu and Droid4X.

Proxifier Settings

On Profile>Proxy Servers:

Add 2 new servers with the following settings:

This should be the result: http://i.imgur.com/sRbRkjP.png

On Profile>Proxification Rules:

Add a new rule with the following settings:

Name: whatever
Applications: click on browse and go to C:\Program Files\Oracle\Virtualbox and select VBoxHeadless.exe
Target Ports: 80
Action: Proxy HTTP 127.01.102
Leave the Enabled box checked

This should be the result: http://i.imgur.com/HDkpWte.png

On Profile>Naming Resolution: http://i.imgur.com/iSpUxxG.png
On Profile>Advanced>Services and other users: http://i.imgur.com/nXz9u9A.png
On Profile>Advanced>HTTP Proxy Servers: http://i.imgur.com/8VhuTvd.png

Windows Settings

On Internet Properties>Connections>LAN Settings: http://i.imgur.com/lOKcaSb.png

Note: This will interrupt your connection, so if you want to keep browsing while sniffing you should configure firefox to connect without a proxy on the Network menu, but if you use chrome you need an extension, i'm currently using proxy helper https://chrome.google.com/webstore/detail/proxy-helper/mnloefcpaepkpmhaoipjkpikbnkmbnic?hl=en
After you're done just leave the "Use proxy server for your LAN" box unchecked to return everything to normal.

Burp Settings

On Proxy>Intercept: Make sure the Intercept box says "Intercept is off"
On Proxy>Options: http://imgur.com/X6Yf7Gc.png
On Extender>Extensions: Load the plugin and keep the plugin window open. It should look like this after you load a fight: http://i.imgur.com/UniyEUH.png

Note: The IP on the SSL Pass Through (23.102.76.23:80) is their logging server, it's unlikely, but it could be different for you, so if you get stuck at the logging screen you should check Proxy>HTTP History and see what's there.
Note: When you load a fight it'll give you a droplist. The plugin is 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?
