Best Potions to Bring to Trial Chambers in Minecraft

Trial chambers are Minecraft's purpose-built combat arenas: room after room of trial spawners, each waking up as you approach, with a Breeze or a pack of strays waiting behind every copper door. Gear matters, but potions are what turn a messy room into a controlled one. These five earn their inventory slots on every run.

1. Potion of Strength

Effect: +3 melee damage at level I, +6 at level II. Brew: blaze powder into an awkward potion; add glowstone dust for level II.

This is the chamber potion, for one specific reason: the Breeze deflects all projectiles, so the hardest mob in the structure has to be fought sword-in-hand. Strength II adds three full hearts of damage to every swing, which shortens every spawner fight in the building, not just that one.

2. Potion of Healing

Effect: instantly restores 4 health (two hearts) at level I, or 8 health (four hearts) at level II. Brew: a glistering melon slice into an awkward potion; glowstone dust raises it to level II.

Chamber fights spike fast — a baby zombie swarm here, a poison arrow there. Healing is the only potion that fixes a mistake right now, with no regeneration delay, and Healing II's four instant hearts will pull you out of almost any bad room.

3. Potion of Swiftness

Effect: +20% movement speed at level I, +40% at level II. Brew: sugar into an awkward potion; glowstone dust for level II.

Spawner rooms are crowded by design, and half of surviving them is positioning: dodging wind bursts, kiting skeletons out of each other's cover fire, retreating to a doorway to funnel a wave. A 40% speed boost makes all of that easier and pairs beautifully with the Breeze fight, where closing distance quickly is everything.

4. Splash Potion of Weakness

Effect: reduces the target's melee damage by 4 points (two hearts). Brew: a fermented spider eye into a plain water bottle — uniquely, this one needs no awkward potion — then gunpowder to make it throwable, and redstone dust to extend the duration.

Throw it at the heavy hitters. A weakened bogged or husk hits noticeably softer, which stretches your armour and your healing potions across far more rooms. Because it is a splash potion, one bottle can debuff a whole cluster pouring out of a spawner.

5. Splash Potion of Harming

Effect: instantly deals 6 damage (three hearts) at level I, or 12 (six hearts) at level II, in an area. Brew: corrupt a potion of Healing or Poison with a fermented spider eye; glowstone dust for level II; gunpowder to make it throwable.

Harming is your grenade. Six hearts of instant, armour-ignoring damage will delete most ordinary mobs outright and soften a whole wave at once. Two warnings, though: it does not stack, so it eats inventory space fast — and undead mobs are healed by it. Against zombies, husks and skeletons, throw splash Healing instead and let the same trick work in reverse.

A Sensible Loadout

For a first full clear, take two Strength II, three Healing II, one Swiftness II for the Breeze rooms, and a pair each of the two splash potions. Drink the buffs as each spawner activates rather than all at the entrance — chamber runs are marathons, and an expired Strength potion in the final vault room is just flavoured water.
