EA's detailed House of Valor, Kingdoms of Amalur: Reckoning's day one DLC, an addition which locks out seven single-player quests for those with owned copies of the game.

The Online Pass for the RPG, which ships in the US today, opens a full faction quest and a set of Mass Effect armour. Details of what's included were released earlier.

"The Grand Champion Tyr Magnus will challenge players to compete in the Valor Arena and overcome all obstacles to survive the barbaric tournament and ultimately seize control of the arena," EA said, as reported by EG.

"As the player battles through the Valor Arena, they will meet new companions and rivals along the way.

"In addition, players can visit the Arena Battle Board to access a nearly endless variety of combat challenges. By completing bonus objectives in these challenges, like defeating all enemies without taking any damage, players can earn unique items and other rewards."

The DLC drew controversy for locking up single-player content.

Kingdoms of Amalur: Reckoning releases in the US today and in Europe on Friday. Get the reviews here.
