Unbalancing Sweep Feat 12
Source Pathfinder Advanced Player's Guide
You make a great sweep about yourself, knocking creatures off their feet and away from you. Choose up to three adjacent foes and choose whether to Shove or Trip all three of them.
Whichever of the two options you choose, roll a separate Athletics check against each foe, performing the same action against each foe. Each attempt counts toward your multiple attack penalty, but don't increase your penalty until you have made all the attempts.

This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.
BarbarianThis indicates abilities from the barbarian class.
FlourishFlourish actions are actions that require too much exertion to perform a large number in a row. You can use only 1 action with the flourish trait per turn.
OpenThese maneuvers work only as the first salvo on your turn. You can use an open only if you haven't used an action with the attack or open trait yet this turn.
