Prepare a thunderwave

You prepare the spell and you pretend to surrender, when they are closer to you, you release it and they are expelled like ragdolls before they even have time to scream. But the deafening boom sounds across the highlands, shaking loose stones from the nearby rocks.

For a moment, there is silence. Far away, you notice more of these creatures coming attracted by the sound.

You can run and try to lose them on the mountainside, there are many caves and will be difficult to follow you, also there are huge cracks in the rock revealing an underground passage.

The caves are a labyrinth, and you can find terrible monsters there, and the underground passage is no better, you don't know anything about the creatures lurking under the ground.
