I think it would be really neat if a consumable item was added to the game that allowed you to chum the waters, attracting 3 to 4 sharks... or other creatures...

This would be an interesting way of 1. defending your own boat against boarding parties and 2. cleaning up the surviving crew of a ship you sunk, and of course 3. sowing chaos and other general piractical shenanigens!
The rarity or cost of this "Chum bucket" would definitly depend upon what it could spawn/summon. I think it'd be nice if an item like this was relatively rare if there was a chance of spawning a serpent or something other than a shark school. additionally, if the sharks it attracted were beefier and more damaging, the item should be rarer/costlier as well.
As an Alternative, maybe the original bucket could have a tertiary function as a chum bucket. where the player could fill up their bucket with chum at an outpost before leaving. this would ensure that the availability of the item was kept to a minimum and that its use wouldn't be too wide spread.
Your thoughts?
