[@Vec] So has Ull'Yang shed his star form (along with its perks), joining the others as a sentient, mobile being?

I fail to see what the perks of being immobile are but to answer your question, no. He created the body out of solidified divine essence, using his true form as a core. Inside his personal plane, he can move freely but outside, he returns to being immobile, only able to influence things inside his physical and mental reach.

He can still do all the things he could do before he created the body. Its just that now, he has more than just his divine essence to interract with his surroundings.
