It is a consumable item, that resets the loyalty of the crew of your ship. It
doesn't check if the loyalty already is higher, or anything really, so using
it can be detrimental if the loyalty is already better than apathetic.
The cost is measly three pieces of fulgurite -- definitely worth the price if
your crew is getting openly hostile towards their captain and you just don't
feel like sinking a thousand ships to get them to trust you a bit more.
The item comes with no warranty, and is available after reboot of October
11th.
