100% no deaths Challenge [permanent death]

So I plan to do soon a 100% of Botw and Totk back to back with no deaths as Challenge. The Challenge will start with Botw and ill have to 100% it before jumping to ToTK. And if Link die at anytime in Botw or ToTK, I must restart the Challenge from the beginning of BOTW.

For example, if Link die at the last boss in ToTK, the runn is dead and I must restart from BoTW.

So, do you guys have any tips that could help me to achieve the challenge? TOTK.Making it easier to track the 100% goal. Since this Reddit is dedicated to TOTK, and Totk is longer and harder than Botw, I would prefer tips for TOTK.

You can suggest one or two extra challenges to spice things up.
