From my experience mastering Minecraft speedrun techniques, potions like the Splash Potion of Fire Resistance and Strength II are absolute game-changers. Using a Fire Resistance potion lets you traverse lava pools and avoid fire damage without slowing down your progress, which is crucial for saving time. Another aspect I found vital is managing your equipment’s durability, especially when under the pressure of speedrunning. Enchantments such as Unbreaking III help extend the lifespan of your tools and armor, reducing downtime spent repairing or crafting replacements. Additionally, combining Strength II potions with well-timed attacks can significantly cut down the time spent battling mobs during your run. Don’t underestimate the value of absorption and regeneration effects to keep your health stable, enabling a smoother and faster playthrough. Also, always keep potions in handy slots like your main hand and quick access inventory, so you can deploy them instantly when needed. Practicing these small but impactful strategies will help boost your efficiency and overall speedrun performance in Minecraft.
