These are very dangerous. If you see one run. They will destroy you in seconds if you are spotted. This thing destroyed my level 999 mutated giga and then broke my metal base into pieces, then it found me. To tame them you must have hundreds of feet of distance and use 1000 cannonballs to the head, then feed exceptional kibble, after about 10 hours it should be at 1 percent tame, at that time you will have used 5,000 narcotics. Good luck!
Encountering this creature will mean your imminent death. If you want to take this you need a tek trap, as they can break metal. It can outrun almost all creatures. It will take approx. 350 shocking tranq darts for a level one and 1240 for a 180.
