I got one of these bad boys yesterday in ark genesis part 2 if you don’t know the R-Reaper Queens spawn in Rockwell’s innards biome! I used a rock drake in from aberration I would recommend having the drakes stats at 1.2k weight or higher 20k health or higher and 10k damage that equals your drake has a damage of 6k use your exo suit if you die to get back fast remember to bring shields (I took 4 wooden shields) and watch out for Arthropods (bugs), Reaper kings and summoners it can be a really dangerous process so be ready! And goodluck!
