AcidIsland#

It's SkyBlock — but the ocean is trying to kill you.

AcidIsland puts players on a tiny island surrounded by a sea of acid. Fall in and you're taking damage. That changes everything: expanding your island becomes a careful, high-stakes operation. Building over the edge is a gamble. And yet players can still boat across to visit each other — if they're brave enough.

It's a familiar premise with one twist that keeps players on their toes the entire time.

Purified water#

Added in AcidIsland 1.22.0

Acid water is still dangerous, but you can now purify it. Drinking an acid water bottle applies vanilla Poison; drinking a purified water bottle restores health. Water items carry coloured lore so you can tell them apart at a glance. Purify water by smelting a water bottle or bucket in a furnace, brewing water bottles with coal, or catching drips from a dripstone stalactite into a cauldron.

acid.purified-water.enabled

Master switch for the purified-water feature. When false, no tagging, furnace/brewing interception, or cauldron tracking happens.

Default: true

acid.purified-water.heal-amount

Half-hearts restored when a player drinks a purified water bottle. 4.0 = 2 hearts.

Default: 4.0

acid.purified-water.bucket-furnace-enabled

Allow smelting a water bucket in a furnace to produce a purified water bucket. Smelting takes 100 seconds (5× a bottle). Set to false if this feels too easy for your server's balance.

Default: true

acid.purified-water.nether-enabled

Run the purified-water mechanic in the addon's Nether world (island or vanilla).

Default: true

acid.purified-water.end-enabled

Run the purified-water mechanic in the addon's End world (island or vanilla).

Default: true

What's new in v1.22.0 — Purified water mechanic

Released: 2026-04-15

Acid water can now be purified so players can safely drink, farm, and bottle it. All water items carry coloured lore — Acid Water or Purified Water — and cauldrons remember their purity across restarts.

  • ⚙️ Purified water added — four ways to purify: smelt a water bottle in a furnace (10 s), brew water bottles with coal, smelt a water bucket in a furnace (100 s, toggleable), or catch dripstone drips into a cauldron.
  • ⚙️ Drinking effects — acid water bottles apply vanilla Poison; purified water bottles heal (configurable via acid.purified-water.heal-amount).
  • ⚙️ New config block acid.purified-water.* (see Configuration section above). Master switch, heal amount, bucket-furnace toggle, and per-dimension Nether/End toggles.
  • 🔡 Two new locale keys under acidisland.purified-water.* for the lore tags; synced across all 18 translations.
  • New events — ItemFillWithAcidEvent and PlayerDrinkPurifiedWaterEvent for other plugins to hook.
  • Code hygiene: pattern-matching instanceof, Math.clamp, reduced complexity in onPlayerMove/getWorld/findEntities/makeNetherRoof, test modernisation.

Release v1.22.0

What's new in v1.21.0 — BentoBox 3.14.0 required, locale migration

Released: 2026-04-12

  • Cherry Grove Sanctuary starter island. A new starter island blueprint themed around the Cherry Grove biome is included for Minecraft 1.21+ servers. To activate it, delete BentoBox/addons/AcidIsland/blueprints/ so blueprints regenerate on the next startup.
  • 🔺 BentoBox API 3.14.0 is now required. Update BentoBox before installing this release.
  • 🔡 All 24 locale files migrated from & codes to MiniMessage. Delete BentoBox/locales/AcidIsland/ and restart to regenerate. Any remaining & codes in custom files will render as plain text.
  • Bug fix: NullPointerException in the EssentialsX god mode check when EssentialsX fails to load at startup.
  • Several pre-existing locale bugs fixed during migration.

Release v1.21.0

Translations#

Help us keep translations accurate

Most BentoBox and addon translations are now generated with the help of AI, so the bulk of the work is already done — but AI is not perfect. What we really need from the community is error reports and corrections.

  • Spotted a mistake or awkward phrasing? Open an issue or a PR on the relevant repository at bentobox.world (a short link to our GitHub org), or tell us on Discord.
  • Want to add a brand-new language? Open a PR adding a new locale file to src/main/resources/locales/ in the relevant repo, or ask on Discord and we'll get you started.
