There is only one spawn of C.A.R.E. robots on Next Island. It is located a few hundred meters South of Shatterroch teleporter. Spawning a tamable C.A.R.A. robot is not very easy as you have to kill around 1,000 L28-L33 C.A.R.E robots first. On the other hand, C.A.R.A. (L21) is quite easy to tame if you have some experience in the profession.
I used a Dominax Original Boiga, Adjusted for the first lashes and then continued with a Dominax Original Cobra, Mentor Edition. Taming was completed within minutes. C.A.R.A. features are not especially exciting. I expected Auto-Loot but this not the case. Its passive effects are Skill Gain - Pet and Taming (10%) and Decreased Critical Damage (3%). You can export your C.A.R.A. pet at level 7 to other planets.
