Legendary Marks are a currency used to purchase weapons, armor, and resources from Vanguard, Crucible, and faction vendors in the Tower. Guardians can earn Legendary Marks beginning at level 18, but are limited to an inventory cap at 200. The Mark system is unaffected by the Weekly Reset, meaning Legendary Marks can be earned indefinitely per week, though only up to the cap of 200. They are also account-wide, thus all characters share and spend from the same Mark pool.
