Haesh makes his way carefully across the deck to the port side where he sees the grappling hook. When he reaches it, he notices three barbed hooks and spears further down the hull, embedded like those on the starboard side, all with taut ropes into the water.
Jandral's Fire Bolt strikes one of the five hooks embedded into the starboard hull, the arcane flame fighting against the torrential rain. With a burst of smoke, the rope snaps and disappears into the water. Now that Jandral is closer, he can see that some of the hooks look like barbed daggers or spears that were thrust into the ship, serving as anchor points.
Rhodrick moves to the starboard rail and sees the same thing, as well as Jandral's successful cutting of one of the ropes.
On the starboard side, an aqua-skinned hand breaks the surface of the water and grasps one of the ropes still attached to the ship. Jandral and Rhodrick see a finned form emerge, with a fish-like face filled with razor-sharp teeth, pulling itself up the hull.
On the port side, Haesh sees two similar piscine forms begin to climb.
