Trip

Trip is an attack combat maneuver which allows a character to attempt to knock an enemy prone. If their trip attempt fails by 10 or more they instead fall prone, unless they are using a weapon to trip the enemy, at which point they may instead drop the weapon as a free action. If a target has more than two legs, it gains a +1 to CMD against being tripped for each additional leg. Some targets may not be able to be tripped, such as oozes, creatures without legs, or flying creatures (However depending on the flying creatures some creatures may allow a character to tangle their wings with a trip maneuver. This is up to DM discretion). A character that is standing up from prone can not be tripped again until they take an action other than the action they took to stand up.
