Minecraft wiki entry for Combat, associated text: The elder guardian has a very large amount of health 80 × 40, making melee kills even harder. Elder guardians do more damage than regular guardians. Fighting elder guardians is incredibly dangerous without armor. Armor worn should include diamond or netherite equipment enchanted with Respiration (or turtle shells due to their longer breath) and boots with Depth Strider. Tridents enchanted with Impaling are also recommended since elder guardians are an aquatic mob. They will also give players Mining Fatigue III, making it almost impossible to tunnel out in case of emergency and to mine the gold treasure inside the ocean monument. It also slows the player's attacks.
