The first Destiny expansion brought many changes to the current method for purchasing Legendary items. In addition to existing currencies that players use for purchasing gear and weapons from different vendors, the Dark Below DLC introduces a new one named Vanguard Commendation.'; document.getElementById("serge_648ac998c20ba86b43957c42").style.display = "block"; } These Commendations are tokens you gain after increasing reputation rank with Vanguard vendor. They can be used for purchasing new Legendary items from Vanguard vendor, which will help you increase your Light and reach Level 30 / 31 without playing the Raids. The only way to gain Vendor Commendations is upon reaching Reputation level 3 and up with Vanguard vendor. Each Reputation level brings you 1 Vanguard Commendation in Reputation Reward Packages delivered by the Postmaster. Commendations can be Vaulted and traded between your characters.

Purchasing the following items requires 1 Vanguard Commendation per item:

• Legendary amour piece – Helmet or Chest
• Any Legendary weapon

How to farm Vanguard Commendations

Before you decide to go farming Vanguard reputation make sure you’re not wearing a factions reputation item – (cape, bond or skirt), as it prevents you from earning vanguard reputation.
