Daily Quests
In addition to the quest chains, there are several daily quests that can be done to earn reputation with the Knights of the Ebon Blade. They are all available once you have completed certain quests in the wow gold long Shadow Vault quest chains and have reached level 80. Each quest grants gold and 250 reputation.

The first three that open up are Shoot Up, Leave our Mark, and Vile like Fire. Start all three of these at the Shadow Vault and then fly to Jotunheim to use the harpoons at 32,24 to shoot down proto-drakes until you are done with Shoot Up. Then move into the town to slay 15 Vykrul and plant your banner in them for Leave our Mark. Lastly steal a green proto-drake from 27,39 and use it to light 8 of the buildings on fire to finish Vile like Fire. This finishes the first part of the daily quests, head back to Shadow Vault to turn them in.

Once you have done more of the quest chain in the Shadow Vault and Death rise another group of dailies open up at the Death Rise. They are From their Corpses, Rise!, Intelligence Gathering, and No Fly Zone. Fly to the Onslaught Harbour near 10,45 and slay enemies to collect keys. Use these keys to open up wow gold trunks to until you collect enough documents to complete Intelligence Gathering. It should be noted that this quest has a very, very low drop rate and takes a long time for the reward. While doing this apply the tincture to the bodies, after you loot them, to complete From their Corpses, Rise! Once you are done summon your bone Gryphon and attack the enemies in the air to complete No Fly Zone.
Rewards.

There are several nice rewards that can be earned with reputation from the Knights of the Ebon Blade. Being an order of Death Knights the best items are melee based. To access the rewards at all you need to complete the quest chain at the Shadow Vault that starts with It's all fun and games, up to the point when you finish Shadow Vault. At this point you can find the Duchess Mynx in the Shadow Vault to purchase items from.
