Tentaclute

Wondrous item, Rare, Requires attunement by a bard

This lute is decorated with swirling waves around the edges of its frame.

As an action, you can begin to play a sea shanty with this lute. When you do, up to 3 tentacles arise from water source(s) within 90ft of you of your choosing. You may spend an action on each of your turns for up to 2 minutes to maintain the tentacles, otherwise they recede at the end of your turn. Each time you spend an action to activate or maintain the tentacles, any tentacle not already grappling a target attempts to grapple a target within 15ft of it of your choosing (Athletics = 4 + your proficiency bonus).

Once used, the Tentaclute can't be activated again until the next dawn.
