I have three of them. 1. I bought the last word from xur, before receiving it twice later that week. 2. My first 3 exotic engrams ever were all insurmountable skullfort (and at the time I had no titan I only had a hunter). 3. I have gotten 3 Gallajhorns from Atheon before I have gotten a Vex (lol so many of u will hate me :P As of now I have gotten 6-7 Gallys, the most common exotic I have gotten)
