Note on the Wiki
As a creative decision, Fathoms' wiki will not be maintained by developers. It may contain some information provided by the community, but it is not a 100% reliable source. If you are having trouble with doing something as the wiki instructs, assume it is outdated. All of Fathoms' content has been precisely designed to be discovered ingame via advancements, the recipe book, and diegetic clues. Additonally, Fathoms is best enjoyed blind...
Frequently Asked Questions
Major Questions
Q: Why is the pack is not appearing on my Modrinth installation? A: Modrinth does not properly install datapacks into worlds directly. You will need to manually insert the datapack and resourcepack into your world's datapack folder and your resourcepack folder respectively.
Q: Why is this visual thing not looking right? A: Install the resourcepack. If you are having trouble finding the resourcepack on Modrinth, click the version you are downloading, not the download button. Scroll down and download the resourcepack.
Q: Is Fathoms compatible with
Content Questions
Q: Is this a datapack? A: Yes. We all make datapacks exclusively, not mods. They all use modern technology (and Smithed conventions!) to ensure the experience is integrated just as a mod.
Q: When are you updating this pack to this Minecraft version? A: We don't know, don't bother us about it.
Q: Will there be a Bedrock port for Fathoms? A: We do not make content for Bedrock.
Q: Can you/I port to this Minecraft version/can you/I port to Bedrock? A: No.
Ingame questions
Q: How do I spawn in items/mobs?
A: For items, run /loot give @s loot <datapack>:item/<item>. For mobs, run /function <datapack>:commands/summon/<mob>.
Q: I am having an issue that has not been fixed by installing the resourcepack! A: Datapacks are not compatible with lots of server software such as PaperMC made by lazy devs who do not take them into account. If you are running a non-vanilla server software, this may be the reason. Fabric, Quilt, Forge, and Neoforge are probably compatible.
Q: Why am I not catching any of the custom fish? A: Fathoms is not compatible with other mods and datapacks that modify fishing loot tables. We can not fix this.

# Changes (SPOILERS!)
- Jinxes have been completely reworked
- Jinxes are now all named "Jinx of <X>" similar to Curses in order to make them more consistently identifiable.
- Individual Jinxes have been reworked and renamed
- Swift Fisher --> Jinx of Reeling - This is the only Jinx that has not been changed mechanically.
- Creative Might --> Jinx of Crafting - Now only applies to chestplates. Now disables all armor and grants much more block interaction range.
- Deep Freeze --> Jinx of Chilling - Now completely disables melee attacks. Freezing deals more damage.
- Removed and replaced some Jinxes
- Rogue Hands - Completely removed. This Jinx was worthless.
- Extract Knowledge - Completely removed. A new mining Jinx is explained below.
- Light Body - Replaced its niche with Jinx of Whiplash, explained below.
- Added 2 new Jinxes
- Jinx of Bulldozing - Applies to pickaxes and shovels. Destroys a 3x3 area of blocks instead of 1. Destroyed blocks will not drop anything.
- Jinx of Whiplash - Sprinting builds up speed rapidly. Stopping sprinting or entering water will violently shock the player, dealing more damage the longer you run.
- Tomes are now separated into different variants based on where you find them
- Mystic Tomes are found in Tarnished Coffers and can contain Jinx of Reeling or Jinx of Bulldozing
- Infused Tomes are found in Caliginous Coffers and can contain Jinx of Crafting or Jinx of Whiplash

# Additions
- Added 4 new fish!

- Reworked the Fathoms menu dialog (accessible from the pause menu)
- Added French and Brazillian Portugeuse translations by Phiphi and Narcikitty!
- Instead of Caliginous Coffers, Tarnished Coffers now drop Chum
- Further tweaked the fishing treasure loot table
- Minnow does not function as bait
- Item updater processes Raw Fish and Aberrated Raw Fish as vanilla Raw Cod and Raw Salmon
- Removed "All That Glitters" advancement
- The reason for this is that we want Gilded fish to be a very optional secret and adding an advancement just for an extremely rare cosmetic drop is not very fair
