Ash notes that the closest troglodyte to him (the one squared off with Masamune) is substantially injured - not on his last legs, but definitely feeling the pain of his wounds. Alara makes the question academic as her nunchaku takes him down with a loud crack.
FYI - Troglodyte 6 (the other normal one on the board) is roughly as hurt as the first one was before Alara killed him
Rawnie's crossbow bolt glances off the troglodyte's scaly hide to no appreciable effect.
The remaining normal troglodyte takes exception to Piper's music and diverts to go after him (and getting too close to that elven woman who dances around the battlefield doesn't seem like an attractive option). The club swing hits with a solid THWACK causing 7 hp of damage to Piper.
Club 6: 1d20 + 2 ⇒ (17) + 2 = 19 Club damage: 1d6 + 1 ⇒ (6) + 1 = 7
The troglodyte hero, as fine and confident a specimen as he is, is undeterred by Alara's prowess on the battlefield and closes to attack her with his own weapon - an iron morningstar.
which I misidentified as a club before, though nothing changed in his failure to hit her
hero morningstar: 1d20 + 5 ⇒ (12) + 5 = 17 morningstar damage: 1d8 + 4 ⇒ (6) + 4 = 10
He lands a heavy blow with it, doing 10 hp of damage.
Party is up!
Trog 1: dead
Trog 6: -7 hp
Trog hero: -3 hp
