Slowness decreases walking speed.
Slowness decreases walking speed by 15% × level; it will contract the player's field of view accordingly. Negative levels of Slowness will increase walking speed. However, jump-sprinting will be barely affected.
Boss mobs are immune to the Slowness effect. While not immune, flying mobs are unaffected by the Slowness effect. Shulkers are also unaffected by, though not immune to, Slowness.
- Spiders, cave spiders, silverfish, and endermites get the effect when attacked with a weapon enchanted with Bane of Arthropods; duration is dependent on the enchantment level and will always be Slowness IV.[verify for Java Edition]
- At levels 7–127, the player will be unable to move on their own unless they jump while moving or throw an ender pearl.
- Alternative methods of reducing travel speed include: walking on soul sand or slime blocks, or through cobwebs; swimming; riding a boat on land; sneaking; eating; drinking milk or a potion (travel speed is reduced while drinking any potion, regardless of the effects of the potion after drinking is finished); aiming a bow and blocking with a shield.
