This snake staff's reason to inflict so much damage to Sylvie's body was sole because of medusa's blessing. Unlike Paula, she didn't have this and could only wail in pain after losing her whole arm.
The sight of cut off arm rolling on the ground was rather devastating.
"It hurts... Ahhh!"
"We have to stop bleeding first."
Reigner reached out for the medicines he had at his disposal. These were only some bandages, common modern staff, and a few medicine pills stolen from the dead bodies of annoying earthlings.
He wrapped those bandages around the bleeding part after Sylvie gulped down the medicine pill, then hugged her to calm down. Only after did she calm down, Reigner reached for her lost arm to freeze it in the vehicle.
'We don't know how far the healing powers go in this world...'
