Every time I try to summon Blingtron 7000, the little purple animation around my character plays for a split second but nothing happens after that.
Are you an engineer, with Kul Tiran Engineering?
The toy lists the requirements. It works for me.
Yes, I am using it on my engineer. I was able to summon the older Blingtrons.
EDIT: I just tried again and was able to summon him. Not sure what was stopping it before.
