Obtaining this creature will require you to enter the tek trench where puprle liquid and the nests of these creatures lay past the bioluminescent chamber, there you must steal an egg and raise in a cold environment feeding it nameless venom you can get by killing nameless
They lose 1 point of food every 15 seconds, so to time how long until they start starving, multiply their current amount of food by 15 and then divide by 60 twice. This will give you the number of hours left untill the food stat reaches 0.
((15 x food)÷60)÷60
The rock drake trench can be found at 57,56 at the area of the map called grave of the lost. Recommend u bring a glider suit and climbing picks and if u have a good tame to fight the drakes. In the wild they can be invisible and can glide in the wild so watch out also wear a HAZARD SUIT it's needed. Lastly there are a lot of nameless in the area so bring a light source. Good luck and ohh it needs to be cold to hatch so air cons
You have to steal an egg like a wyvern. I used a lot of ziplines and a high level ravager to get down there, used the pick to climb up to an egg and ran. The drakes nearby WILL aggro on you. I got on my ravager and ran away on the ziplines. Make sure you have a hazat syit to protect you since there is radiation down there.
Use climbing pick's to climb up to a nest and make sure that there are no Drake's then take the egg and glide out on a wingsuit. You can out-glide a Drake.Stay clear of the water and a have a shoulder pet to stop the Nameless. Have a hazard suit on and you need like 20 air conditioning units to make it hatch. Feed it Nameless venom to raise.
Steal a egg to tame took me alot of AC units around 20 of them just to hatch one egg hazard suit needed to get the eggs since its at radiation. They have a cloak ability and gliding ability that can get you around very fast. Climbs lime a megalania which is sick! Goodluck to all you sirvivors getting eggs. Rain out!
Requires stealing a Rock Drake egg, and raising like the Wyverns in Scorched Earth. Won't eat meat as a baby, but WILL eat Nameless Venom, so I would suggest hunting Nameless until you have a nice supply of it. It also requires cold temperatures to hatch, so make use of air conditioners.
I went down there with three friends, we all had (somewhat) decent crabs. It took a while to get down there, but since the crab can jump, it is easy to get the eggs. Also, because the crabs is so powerful, you can easy kill all of the drakes (especially with four people).
