None, besides a few bones if you call those something to be owned than Dozer has many, buried here and there.
Protective of the area Dozer currently is at that moment in time or the area the Nnar' has been told to protect, it will attack without warrant all who are perceived as intruder or enemy. Other than that Drezkin is quite tame with more intelligence than standard Nnar', Dozer gives the same as the Nnar' is dealt.
Like most Nnar', Dozer has a potent venom within the constructs teeth. That can paralyze and slowly eat away at the targets bloodstream like an acid. This Venom has the ability to siphon life away from the victim leaving no physical tell tale mark up the target besides the initial bite wound. The Venom also evaporates the blood leaving nothing left behind as far as bodily fluids go.
Dozer has the ability to mind speak with whomever is in direct proximity to the Nnar'. As the Nnar's actual voice would be way to graveled and raspy to understand. What stands out with Drezkin's mind speech is in the way it sounds to the one being spoken to. Even if the Nnar' has never heard you speak the voice in which you hear would be that of your own, as if you were thinking to yourself, a slower, to the point, intrusive version of yourself, but still recognizably your own voice.
(Pictures above my add a write-up later)
Bleached white bones, i'll bet slight red and yellowed teeth and claws. Shoulder height Drezkin is about six feet tall, stocky, with a scorpion stinger at the end of the Nnar's tail.
