With a built in defensive laser system, the hydro trident converts seawater into a concentrated beam to keep hostile predators at bay. The trident itself can also be thrown like regular tridents. Loyalty enchantment not included.

--DATABANK--
The Hydro Trident is an experimental underwater weapon designed by Erichary.

While it has can be thrown like any other tridents, it has a built in hydro laser cannon, which absorbs the surrounding water and converts it into a beam of concentrated of energy. Note that it is still a prototype, so the laser itself won't be too destructive, but it's still strong enough to deter predators, particularly leviathans. While it also draws a lot of energy, the battery cell is rechargeable.


Advice against using it on a direct line of sight with another personnel.


P.S. "Erichary" is the name of the company Eric's dad work at
