Sand Worm Invincibility glitch

To start off on how to do this glitch. I first began rolling on the sand cloud?(Idk this itself is a glitch/You can also jump over) ANyways. You roll on the sand trai and stay there for a while. If it doesnt work roll on the chest while the sand trail chases you. (Please keep in mind occasionaly it doesnt work). And thats all. STEP1: Roll on the sand trail

Step 2: Roll on the chest while the sand trial chases you just in case

Step 3: Things that should happen: You die, you live and the glitch works.

yeah so rez its a pretty major bug so fix it? Idk just letting you know cause it can be exploited.
