Im seeing a lot of avoidance here mate and a focus on parts of what ive said without and talking about them instead of answering my questions and providing the proof you need to for your argument to actually hold weight.
What proof have you got that Lokis shape shifting makes him more durable?
If we were to assume that unproven point correct, what proof have you got that he had invoked that ability just before being incinerated?
Now youre mentioning the Norn Stones. Cool. Can you tell me what effect they had on Loki in that scene apart from amping his energy projection, because you do know as stated by Loki himself the effects of the stones vary from user to user and i hope youre not assuming that Lokis durability was amped and are then gonna try and use that point to hype Voidtrys feat further?
