This is a mod that introduces a new enchantment. This enchantment with imbue the trident with Dolphins Grace. To use the effect, the trident will need to be in your off hand. As long as it is in your off hand, the effect will not go away. Once you switch to your main hand, the effect will wear off in 2 seconds. This is for those moments where you need to slow back down; for example, if you reach your destination.
If you combine this with Depth Strider boots, you can zoom across vast bodies of water.
*The enchantment can be found in villager trades and only has one level.
V2 of the mod has this feature as V1 mistakenly did not have it enabled. It has been uploaded 1/23 and should be viewable soon.
