This mod adds two new enchantments, Grapple and Aer Hook. These enchants can be added to fishing rods, even modded fishing rods.

Grapple

Allows your fishing rod to be used as a grappling hook. Cast the rod, land the hook on a solid block, and then uncast the rod to be pulled or 'grappled' to the hook location.
You will not be grappled if the hook is in a liquid, so you can still fish with your newly enchanted rod.
Each level (Grapple I, Grapple II, Grapple III) determines the grapple cooldown and strength, pulling you farther and higher.

Aer Hook

Allows grappling without being hooked onto a solid block.
Does nothing without the Grapple enchant.

Both enchantments have a roughly 30% chance of spawning in Buried Treasure Chests and Ocean Ruins Chests. And there's a 100% chance for either the Grapple enchant or the Aer Hook enchant to appear in a Woodland Mansion Chest.

The enchantments are completely data-driven (as of version 1.0.2+). This means you can change the cooldowns and pull strength when grappling, simply by making a datapack and overwriting the file found at data/grapple/enchantment/grapple.json.

Golden Cookie

Available on versions 1.0.2+.
Eating a Golden Cookie gives speed for 4 seconds and adrenaline for 8 seconds. Adrenaline is a new status effect that prevents fall damage and grappling cooldowns. This can be configured using the gamerules adrenalinePreventsFallDamage and adrenalinePreventsCooldown.
