Worn Chainmail Helmet Book

A worn Chainmail Helmet Book that has become unreadable.

It can be found at the Pirate Event, or players can obtain it when the Chainmail Helmet Book becomes unusable. If players combine two of these then they can craft a new Chainmail Helmet Book on the condition that they have already unlocked the recipe of the Chainmail Helmet Book in the Workbench. Stackable up to 2.
