How To Make A Potion Of Harming

The actual mechanics behind throwing damage potions in Minecraft

Potions of Harming are straightforward in theory but the brewing process has some specifics that trip people up. You start with awkward petals, which you brew with water bottles to make a potion of awkwardness. From there you add fermented spider eye to turn it into a potion of brewing. Add gunpowder to extend the duration, then glowstone dust to strengthen it. The strengthened version becomes a Potion of Harming II if you want the extra damage. Blaze powder is the fuel source for your brewing stand, and you need at least one water bottle per potion you're making. I remember burning through three stacks of blaze powder and four batches of awkward petals before I actually got a clean Potion of Harming. The issue was I was using the extended duration version when I didn't need it, which just made the potion weaker overall because the harming effect scales differently with the splash variant. What actually works is keeping it basic: water bottle, awkward potion, fermented spider eye, and stop. No glowstone, no redstone extensions. One batch takes about two minutes if your brewing stand is stocked properly. Here's the thing most guides don't mention: the fermented spider eye ingredient doesn't just invert the potion effect like you'd expect with other combinations. It actually creates a fundamentally different base potion. A Potion of Harming is not a reversed Healing potion, even though the brewing logic makes them look related. They're separate effects with separate scaling. This matters because you can't take a Potion of Healing and flip it into something useful by accident. It either becomes harming or it becomes a water bottle, depending on what else is in the mix.

You'll need these ingredients in order: water bottles (filled from a cauldron or source block), nether wart for the awkward base, fermented spider eyes (bred from regular spider eyes using a brown mushroom and sugar), and optionally gunpowder or glowstone if you want variants. A brewing stand costs four blaze rods and three cobblestone. Flint and steel lights the stand. Glass bottles are six to a stack and you fill them at any water source. The brewing interface has three bottom slots for water bottles and one top slot for your ingredient. Place the ingredient, wait for the progress bar to fill, and the potion moves to the output slot. Repeat for each batch. An awkward potion takes about ten seconds. Adding the fermented spider eye takes another ten seconds. Total per potion is roughly twenty seconds including the initial awkward step. If you're making multiple, stacking them all in the bottom slots cuts this down significantly since the brewing stand processes all three simultaneously. A common mistake is trying to use redstone dust with the potion, thinking it'll prolong the harming duration. It won't. Redstone extends the duration of positive effect potions, but harming has no duration to extend. The game simply ignores it or converts it based on what the resulting effect actually is. You'll waste that redstone and end up with nothing. Stick to the core recipe and save your materials.

If you want a splash version, add gunpowder after the basic Potion of Harming is done. This changes it from drinkable to throwable with a range of about eight blocks. The damage radiates outward and decreases with distance from the impact point. Lava blocks and fire resist you to the brewing area, not the potion itself. Brewing stands can safely sit near lava if you keep the fuel stocked from a distance. The damage numbers work out to six hearts on difficulty set to normal, four on easy, and eight on hard. The II variant adds another six, four, or eight hearts respectively. Against mobs with absorption or regeneration, the harm still applies as the primary effect, but those secondary mechanics can offset the damage. Endermen take double harm because they're undead-adjacent in the game's code, which is why they're good targets for testing if you're unsure whether your potion is working right. Crafting table setup for the brewing stand itself: three cobblestone across the bottom row, one blaze rod in the center, one more blaze rod directly above it. That's all you need to make the stand. After that, everything is just feeding ingredients into it and waiting.

I keep a small brewing station near my base with a cauldron full of water, a stack of glass bottles, and a chest organized by ingredient type. It cuts the prep time down to almost nothing when I need potions quickly. The whole process from start to finished splash potion of harming II takes me about eight minutes once I have everything laid out. Without organization, it's closer to twenty because you're walking back and forth constantly looking for items you should already know where they are.
