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
I was with a decent size tribe with a bunch of friends.They raised a bunch of rock drakes when i joined them.However, there was one Rock Drake in Particular that was laying in the corner of the dino pen that has been neglected, never being used cause previous owner from the tribe has stopped playing ARK. The tribe decided that i earned the right to claim the Rock Drake as my own. It was only a 140, but i cherished that thing like a real buddy.I named him "Anon Loves me".Because he always had my back in the darkest time. When i first glided through the air with the drake. It showed me a side of ARK i never knew before, and showed me the oppurtunities the world had to give to me.
Unfortunatly the happy moments came to an end. We got attacked by a bigger tribe while i was on. My tribe leader insisted i flee and transfer servers. However, i could not take "Anon loves me" at the time cause of the sudden ambush. The Rock Drake and I looked at each other one last time before parting ways..
Another way to do the math for food stat loss when raising rockdrakes. They lose 1food per 15 seconds. you lose 4 food every minute. (My advice go up to 5 if your paranoid like me and get Arked. 60mins x 4food = 240, (240 is the total food stat loss per hour.)
Now take your total food stat and ÷ by 240, and you will have a correct time as well.
The Rock Drake is a gliding creature that has the ability to cloak itself and its rider. Using a Rock Drake's excellent climbing skills, survivors can traverse across steep cliffs. The Rock Drake can only be found in a particular cavern and is relatively tough to tame.
