What character class (Titan, Hunter or Warlock) did you claim the Fated Engram on?*
What non-quest reward year 1 (pre-Forsaken) exotic item were you hoping to get?**
* - You cannot get exotic armor for a different class that claims it. Meaning, a Hunter will never receive Titan or Warlock armor.
** - You cannot receive weapons/armor that are rewards for quests/pursuits (Mida Multi Tool, Sturm, Legend of Acrius, Simulant, etc.). You also cannot receive exotics released in Forsaken.
Fated Engrams do not give Year 2 exotics, and can give duplicates if all Year 1 exotics for the class you are on have already been acquired (for example, if you have all Warlock exotics, you can get a duplicate by getting the engram with a Warlock).
