Item: Tidal Fishhook

Finesse: You can use your Dexterity modifier instead of your Strength modifier on attack rolls using this melee weapon. You still calculate damage using Strength.

Grapple: You can use this weapon to Grapple with the Athletics skill even if you don’t have a free hand. This uses the weapon’s reach (if different from your own) and adds the weapon’s item bonus to attack rolls as an item bonus to the Athletics check. If you critically fail a check to Grapple using the weapon, you can drop the weapon to take the effects of a failure instead of a critical failure.

Tethered: This weapon is attached to a length of rope or chain that allows you to retrieve it after it has left your hand. If you have a free hand (including if you've just thrown a two-handed tethered weapon and have a hand holding nothing but the weapon's tether), you can use an Interact action to pull the weapon back into your grasp after you have thrown it as a ranged attack or after it has been disarmed (unless it's being held by another creature).

Thrown: You can throw this weapon as a ranged attack; it is a ranged weapon when thrown. You add your Strength modifier to damage as you would for a melee weapon. When this trait appears on a melee weapon, it also includes the range increment. Ranged weapons with this trait use the range increment in the weapon’s Range entry.

Water: Effects with the water trait either manipulate or conjure water. Those that manipulate water have no effect in an area without water. Creatures with this trait consist primarily of water or have a connection to magical water. Planes with this trait are mostly liquid. Visitors who can’t breathe water or reach an air pocket likely drown. The rules for aquatic combat aquatic combat usually apply, including the inability to cast fire spells or use actions with the fire trait. Creatures with a weakness to water take damage equal to double their weakness at the end of each round.
