My first time playing Master Mode I quickly learned I needed to play in stealth mode. There’s a stealth costume, potion, speed potion and attack potions etc those help alot. The assassin strike is great cause it takes out a huge chunk of health. Learning how to quick shoot bows to keep health from regenerating or cause them to be stunned. Using bombs, time-stop magic, fire, electric and cold attacks to stun them during your combos also help. One Durian, one apple all you need for best life recipe, collect Dragon horns to make the longest lasting recipes… those the only tips off top of my head. And use your map to mark great spots to collect weapons and resources you need. For example I marked a spot on my map that is right next to the faron woods dragon spawn location when he rises up from the lake. All I have to do is set a campfire and every morning the dragon respawns. Collect horn, then set camp for the next morning. Rinse wash repeat.
