Usage: ```node showMeMyDrops.js [your session cookie]```

Prerequisites: I've only tested this on a Mac with an iPhone 7.

That said, as long as you have your session cookie, it should work on platform that has node installed.

The tricky part is getting your session cookie.

The way I did it is outlined here: http://useyourloaf.com/blog/remote-packet-capture-for-ios-devices/

Once you have that setup, you'll have to look through the packets for a section that looks like this:

```
		GET /dff/battle/?timestamp=1483926335&battle_id=1050901738 HTTP/1.1
		Host: ffrk.denagames.com
		Cookie: http_session_sid=xxxxxxxxxxxxxxxxxxxxx
		Connection: keep-alive
		Upgrade-Insecure-Requests: 1
		User-Agent: Mozilla/5.0 (iPhone; CPU iPhone OS 10_1 like Mac OS X) AppleWebKit/602.2.14 (KHTML, like Gecko) Mobile/14B72c
		Referer: http://ffrk.denagames.com/dff/?timestamp=1483926300
		Accept-Language: en-us
		Accept-Encoding: gzip, deflate
```

The key in all that mess is "http_session_sid" - find that and you're golden (don't copy any semicolons)

Once you have that just run this from terminal, command line or whatever.

```
node showMeMyDrops.js [your session cookie]
```

And then go into a battle.

Every few seconds, the script will print what you're going to get.

Couple things to note:

1) If you're not familiar with technical stuff, this might be more hassel than it's worth
2) I won't be able to offer much in the way of support, but I will try to update the Id map. Right now it's just going to show Greater, Major and Crystals - if you know JSON and want to help me out with more, awesome.
3) It doesn't work with MP Raid Dungeons (solo is fine). This is intentional.
