I ran Regicide last night and consumed 44 3oC over 2 straight hours. 6 exotic engrams. Some would pop within minutes of another, sometimes it was 20+ minutes before another fell. But right on the mark for about a 1 in 7 drop rate. I took a couple minutes to start setting up OP's loop this morning. I only setup Shrine of Oryx and Eye of a Gatelord, then ran Ultra Knight. Confirmed I did have my checkpoints, got one exotic from Shrine. Anyone setting this up, it's CRITICAL you get to orbit before the end of mission countdown timer starts. If the countdown starts, you've lost your checkpoint and will have to re-run the mission from scratch. FWIW a 386 Gjally is gonna knock out these Ultra's some in one shot, most in two. For those of you who don't understand WHY DO THIS, once you're at or above 385, decrypting exotics to incrementally infuse into your other weapons and armor is the simplest way to build your overall light quickly. Especially if you've already got a set you like and don't want to trust to RNG you'll get equal or better perks/etc. from the next one of that weapon/armor you get from a legendary decrypt or faction rank up package.
