I was playing earlier and all within an hour I got my 3rd NLB all from RNG and a second Gjallarhorn from Iron Banner and the day before I got Efrideets Spear and re-rolled it to have Last Round, armor piercing, and "easier to aim under fire". Most insane luck I've had except maybe when I got my first Gjallarhorn and a my second vex in one reward from hard Atheon.
