Sterling Anchor Pendant

A shiny silver pendant in the form of an anchor, worn around the neck in a chain.

You can use a bonus action to speak the command word of the pendant to turn it into a full-size ship's anchor, complete with ten fathoms of chain ("Dropping anchor!" to enlarge it, "Anchors aweigh!" to shrink it again).

While the anchor is enlarged, you can use it as a maul, gaining a +1 bonus to attack and damage rolls with it.

You can also throw the anchor as an action on the same turn you use to enlarge it. If used this way, you make a ranged weapon attack using Strength against a creature within 60 feet of you. On a hit, the target takes 27 (5d10) bludgeoning damage. You can only throw it like this once per long rest.
