Sorry for audio/video not synced. geforce experience blows.
8 megalosaurus w/ ~20k health. 3 with ascendant 100 saddles, the rest with journeyman 54.7 saddles.
3 reaper kings at 80k health and between 800-1100 melee.
Rock drake 25k health, 700 melee, 1600 stamina.
212% damage shotgun (plus backup) and 200% fab rifle (plus backup) for Rockwell's BAWLS.
What I'd do different: Definitely need a better shotgun. 8-9 rounds for one tentacle takes too much time, especially when the reapers come. I'd also probably pump a little more stamina into the rock drake, it could've been dangerous if I had any less. I'd take a second set of better armor too (I didn't because I was lazy and just wanted to fight him already). I had one "good" set and another "meh" set. It worked out, even though I was mostly naked by the end.
