Once you get closer you will see one brave who is normal-colored fighting 2 braves who've gone silver-screen. They're all in melee with each other in a blocked-off tunnel, so they're all adjacent.
The Pummel power is in the SW Deluxe book. If you don't have it, I have a write up of the power in the
System Info and House Rules thread. For ease of reference, here's a copy of what's written there:
Pummel
Rank: Seasoned
Power Points: 2
Range: Cone Template
Duration: Instant
Pummel allows a character to knock down multiple foes. The caster makes an arcane skill roll and then places a Cone Template in front of him. Any friend or foe touched by the template must make a Strength roll (at –2 if the caster gets a raise). Any target that fails is knocked back 2d6” and becomes prone. If the target strikes an inanimate object, he is Shaken as well. Targets with cover may subtract the cover modifier from the total distance moved (to a minimum of 0), and flying targets suffer an additional –2 to their Strength roll.
