I load a rock drake up with four hazard suits, a few stacks of carrots to replenish food and water, and head down. With that you can pull eggs for a couple hours. Make sure to take a spyglass so you can track low level drakes and kill them so higher level eggs spawn! I level a rock drake to 15000hp, 1500stam, and use it to pull more eggs! I recommend putting extra points into melee then weight.
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
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
