In order to beast, one gathers together one's friends and ventures to the nearest park or nature preserve. Upon arrival, one gallivants about the woods in search of all manner of beasts. Don't get too complacent, however; many such beasts will not take kindly to your intrusions, and may lash out when cornered. Thus the wary beaster always has an air of caution while beasting, lest he find himself the prey rather than the predator.
