Commune With Vermin

You gain the ability to comprehend and verbally communicate with one species of vermin that you can see. The knowledge and awareness of many beasts is limited by their intelligence, but at minimum, beasts can give you information about nearby locations and monsters, including whatever they can perceive or have perceived within the past day. You might be able to persuade a beast to perform a small favor for you, at the GM's discretion. While this seems utterly practical, the connection works both ways. This means that the target(s) might be not be interested in breaking it. Usually animals tend to lose interest when ignored but might lack the insight or willingness to actively shut down this communication. This means that the caster may hear the animals ranting for a while after.

This so for a 1D20 number of time units which can be: (1D12)
1-5: minutes; 6-9: ten-folds of minutes; 9-11:hours or 12:days.

The effect will however vanish as soon as the caster moves out of the sight And hearing range of the involved parties. (If the caster did target a rat it might take until ALL rats and the caster are out of one an-other's sight and earshot)
