Rat King

As a rat, you are entitled to an unspoken bond carried by your species. Your numbers are many, but your hearts are one.

In a safe environment, as a ritual action, you can spend 30 minutes letting out a pattern of ultrasonic chirps that most other critters aren't capable of hearing. This will summon another rat who's chosen to answer your call for aid. You may ask them one question. The DM will roll the necessary check, adding your Wisdom modifier, to see how the rat may answer you. This can be done twice per long rest.

At level 7, you may ask up to two questions on the same topic at the DM's discretion.
