A Free Reusable Flask on 10M Timer, +500 to Each Stat, 2h ~ Farmed from MoP Rare

Some if not most of you might have seen or collected this by now, but people with newer characters in Pandaria content would really enjoy having this loot.

CRYSTAL OF INSANITY ~ dropped by rare spawn lizard man Sulik'Shor in Valley of the Four Winds.

Sulik'shor 

Sulik'Shor's chance to drop this thing (the crystal) is about 10% according to Wowhead.

The dude spawns like a typical MoP non elite rare, about once per 50 min or less.
So you can park your toon there and chill out waiting for him to return.


There is also a small chance he can drop the Brawler's Guild invitation. (.

One day I was hunting Rares in a zone where I'd done no quests and after killing Sulik this FINE FINE treasure was in my bag.
And I thought it was a Void Crystal and put it in the bank for about a week without using it... oh my god.

So just in case you're an enchanter be careful, it's not a crystal it's a free alchemist flask for all professions ....
