Heroes of the Storm Eternal Conflict Update

Heroes of the Storm is finally getting the Eternal Conflict main content update today, with the servers undergoing maintenance as we speak till 11:00pm PDT.

The main bulk of today's content update centres around the new map, Battlefield of Eternity which we've covered at length a few days ago here.

Aside from Johanna the Crusader which was released last month as part of the Diablo-centric content update during the official launch, Eternal Conflict will be getting another new hero, the Butcher, whose skills overview can be seen in the video above. There are a few more heroes lined up, such as King Leoric and the monk, so be sure to keep a look out for them!

As part of the Eternal Conflict celebrations, Blizzard devs have also included a Treasure Goblin mini-game of sorts at the start of every battle (a feature of Diablo III). Here's how you can actually participate:

It seems that mischievous Treasure Goblins have snuck into the Nexus alongside the arrival of the Burning Hells. These devious creatures are intent on pilfering as much gold as they can carry, and while their numbers are yet unknown, the fortunes they've scavenged must be returned! Adventurers that manage to slay any Treasure Goblins they encounter during the Eternal Conflict will be handsomely rewarded. A Treasure Goblin will do anything in its power to evade those it deems hostile, so dispose of these timid beings swiftly, lest they open a portal and slip away!

• Players will receive a Special Event Quest titled: “Kill a Treasure Goblin!” each day during the Eternal Conflict event. 
• Before the start of a match, any players with an active Special Event Quest will cause a Treasure Goblin to spawn at a random location near their team’s Core. 
• Kill the Treasure Goblin before the pregame timer reaches 0, or it will open a portal and escape the Battleground.
• Any players with an active Special Event Quest that manage to kill a Treasure Goblin before it escapes will receive 100 Gold for their efforts at the end of the match. 
• Treasure Goblins may spawn on any Battleground, in any matchmaking game mode (Versus A.I., Quick Match, Hero League, Team League). 
• This Special Event Quest is available to all players, whether or not they’ve unlocked Daily Quests by reaching Player Level 6. 
• While players are invited to kill as many Treasure Goblins as they can, this Special Event Quest can only be completed once per day. Incomplete Quests do not stack.

In addition, the update will contain a long list of bug fixes, making this the largest patch since the official launch. There are also a host of balance changes, designed to make certain heroes more competitive (and others less so because they were seal-clubbing everyone else).

More information on the balance changes and bug fixes can be found in the patch notes here while waiting for the game to come back online.
