"Diablo III's" latest patch contains one "Fallout" easter egg that could make at least a few fanboys smile and chuckle a bit when they see it.

The new item in question is known as Boyarsky's Chip, and it is a legendary gem that has just been added to the game.

What's most interesting about Boyarsky's Chip is its description, which says that it "was discovered in an underground vault by old man Boyarsky."

That little line of text actually contains two references. 

The first one, pointing out to the where the gem was found, is a reference to the "Fallout" franchise, which, of course, is a series that has popularized the presence of underground shelters, or "vaults" in the game's parlance.

The other reference is to the name of the man who stumbled upon the gem. "Old Man Boyarsky" is actually a reference to Leonard Boyarsksy, who is a member of the "Diablo III" team. Boyarsky also worked as the art director for the original "Fallout" game and also designed numerous gameplay elements in the second installment of "Fallout" according to Kotaku.

As for the item itself, Boyarsky's Chip seems to be useful enough as it adds 30,000 thorns to a piece of jewelry it is embedded into.

Outside of Boyarsky's Chip, the next patch coming to "Diablo III" will also be bringing in other interesting additions.

Most notably, players will soon be able to access a new area in the game known as Greyhollow Island.

The upcoming patch is also adding two expanded zones. The first expanded zone, known as Eternal Woods, will be added to The Ruins of Sescheron, while Leoric's Manor will be growing larger, thanks to the addition of the Royal Quarters, according to Battle Net.

Numerous items and item sets are also being tweaked by the latest patch coming to "Diablo III."

The game's latest patch is already available in the "Diablo III" public testing realm.
