Hvísla Rune

A Hvísla Rune allows you to talk to a player the following night. The other player will see all the messages you send at night but will not know who is sending them.

It is also called "Whisperrune".

Holding it will make you appear as a Witch Craft user to intel checks. After use, a Rune must recharge and can be used again by you three nights later. If you pass the Rune to a different player they will be able to use it immediately.
