Custom enchantments are a thing we have plenty of here on Peaceful Farms, and they all do a variety of things! Here's what each of the ones that we know do. (There isn't clarity on the Haste enchantment, just a guess.) AntiGravity - Increases Jump Height. Bait - You will get rarer fish. (As far as I've tried, this only applies to spawn fish, but I'm sure it applies to outside of spawn too.) Blast - Mines a 3x3x1 radius at level 1. Level 2: 3x3x2 and so on. Doctor - Heals you as you shoot. Excavation - Blast for shovel. 3x3x1 radius and so on for levels. Experience - Gain more experience for mining blocks you can get XP from. Furnace - Auto Smelts blocks you mine. Gears - Increases movement speed. Haste - Makes any actions you perform quicker. (I think.) HellForged - Repairs items as you walk. Springs - Increases Jump Height. Telepathy - Blocks you break are instantly moved into your inventory. Implants - Feeds you as you walk. There are a few more, Overload and Nursery, but those aren't on any items that are currently obtainable anymore as far as I know, so I haven't gotten any information on what they do.
You seem to be missing the implants enchantment which is on the vote helmet and feeds you as you walk
As far as I am aware Bait only increases the size of any custom fish but doesn't affect the odds. However Bait caps all sizes to .0cm instead of .9cm so the max size you will get is 1000cm using Bait instead of 1000.9cm without using Bait (note that it's way more useful to have bait as the numbers before the comma will always tie or be higher than if you didn't have Bait). Great post though ^^
New cosmetic enchantments have been introduced in the spring and summer of 2022 such as Pastel Pop on most Easter tools and Bubbles on all Ocean tools. Pastel Pop spawns some cute pastel particles when breaking/hitting something and Bubbles spawns little bubbles.
