Shadowfell's Favor

You have captured the attention of the Shadowfell, and the gods ruling over it have given you a blessing. You gain the following benefits:

You always have Darkness prepared and can cast it at will an amount of times equal to your proficiency bonus. In addition, you can use a Magic action to summon a Bat. You can cast Animal Messenger on it without material components. You can't use either property again until you take a long rest.
