Katz-ne-ate |

If the description above is accurate, and we really can't see anything, Katz will do the following. Sorry, the hissing for the previous action was him telling his scorpion to run to him. The scorpion would have covered 160ft from Korren to Katz. Then charging this round for 70ft to the bandits. Scorpions have Darkvision and Tremorsense, so it should be good.
Katz continues to hiss To the scorpion Kill the wounded one! Changing voices to common Everyone! Attack now! He then waits for the bandits to make targets of themselves. Ready action to shoot if the bandits create a light source/become visible.
If there is enough light to see the bandits, Katz will say the same things, but just fire at the wounded bandit rather than wait.
Longbow with hunter's band activated 1d20 + 9 ⇒ (12) + 9 = 212d6 + 1 ⇒ (2, 3) + 1 = 6
Scorpion's sting attack 1d20 + 6 ⇒ (7) + 6 = 131d4 + 1 ⇒ (3) + 1 = 4 + poison(6 rounds 1 str damage each round DC13
This may seem a silly question, but when a creature with multiple natural attacks moves, it can still only attack with one, correct? To use multiple attacks it would have to follow the full-attack rule of not moving more than 5ft?

Yep. A full attack actions need a full round action.
From outside the dust, that is slowly setting, you can hear a man screaming in pain, and more people coughing: the sleeping guards are now waking up and rising. Nobody ventures out of the dust so far.
1d20 + 6 ⇒ (7) + 6 = 131d20 + 6 ⇒ (1) + 6 = 71d20 + 6 ⇒ (8) + 6 = 14
Korren and Shosuro, you are up now. Korren is still pretty distant, and Shosuro is in the dust too. Korren, you notice that the Elven Warrior are slowly getting down the path.

Perception with low-light vision to see Shosuro and Katze.
1d20 + 7 ⇒ (4) + 7 = 11
Jin almost lets his second arrow fly but is unsure of where Katz and Shosuro were standing
Blast! We do this the true warrior way now.
Jin drops his bow to the ground and his Katana appears in his hand. He bellows DUTY!! HONOR!!
and charges the man with the arrow protruding from his body.

Sorry, was very busy
Korren rides halfway down the path, overtaking the elven warriors.
Meanwhile, you can hear the guards stumbling to get outside the cloud of dust, and the cocking of a firearm. Then a powerful shot
Shosuro gets out of the way just as an handful of pellets flies past him: the attacker just didn't see him.
1d20 + 5 ⇒ (7) + 5 = 12
The axe guars tries to chop the head of the charging Jin, but misses. The samurai instead strikes true despite the darkness, killing him.
1d100 ⇒ 671d100 ⇒ 65
1d20 + 7 ⇒ (2) + 7 = 9
To clarify: everything inside the cloud has total concealment (50% miss chance) while outside it's just (20%), assuming nobody sets up a light source.
Katze is up.

Korren Blake |

If I hear the firearms being loaded from where I am I will ride forward and ready an action to fire.
Perception: 1d20 + 10 ⇒ (20) + 10 = 30.
Otherwise I will remain where I am about 80 feet from the ridge.
In case I end up shooting this round:
Attack vs. Touch AC: 1d20 + 8 ⇒ (6) + 8 = 14.
Damage: 1d10 ⇒ 4.

Jin-Darus |

Jin follows through with his slash and steps up to the man getting his weapon reloaded
not sure if i was close enough to AOO him but i am moving in to attack and roll both.
He slashes hard at the mans lower belly to allow for a follow up after this attack.
AOO for reloading 1d20 + 10 ⇒ (4) + 10 = 14
Damage 1d8 + 8 ⇒ (2) + 8 = 10
normal attack 1d20 + 10 ⇒ (6) + 10 = 16
damage 1d8 + 8 ⇒ (8) + 8 = 16

A Fistful of Koban |

Rolling concealment...
5d100 ⇒ (60, 97, 1, 43, 85) = 286
Shosuro, you see a man going out of the could, that receives an arrow in the knee from Katz-ne-ate. Your sword slash is enough to finish him.
Korren, despite the dust and the darkness, is able to make out a shadow within the camp area that is reloading a weapon, and hits him with a bullet. The man screams, and moments later another shot is being fired haphazardly at your general direction, missing you. You also see that the elven warriors are now charging at the camp, screaming about their enemies' demise in their native tongue.
Jin, a buckshot grazes you: the man with the gun is very close. Although you missed while he was reloading, your second attack literally decapitates him.
1d20 + 5 ⇒ (20) + 5 = 25
1d20 + 5 ⇒ (14) + 5 = 191d8 ⇒ 1 Jin take 1 point of damage
The dust finally settles.

Jin-Darus |

Jin moves around among the corpses and checks to see if all are truly dead. Checking the wound he recieved he knows that it will be an addition to numerous scars he has gained in his warlords service.
These men were ill-prepared. We can only hope that the full gang is as bad as this. I do not believe the next group will fall so easily.
He pulls his long-stemmed pipe from its case and packs it. LIghting the sweet tobacco he begins to add some markings to his scabbard whilst murmuring something to himself. He stands when finished and draws deeply on the pipe for a while.

A Fistful of Koban |

Sorrounded by armed and dangerous people and with his leg hurting for a bullet, the man drops the shotgun and reaches for the sky. Alright, alright, just, don't kill me, ok? There is a path leading downwards the Canyon, through that opening in the rocky wall. You will find Slate and the rest down there. He then slowly backs up towards the pathway you came in, with a worried look on his face as he moves close to the elven tribesmen.

Jin-Darus |

Hold your blade Shosuro. He is nothing to us now other than someone the law should deal with. He has given us information that will aid us in catching the true criminal and he is unarmed. We can bind him and allow justice to take its course with him when we return to town.
Jin will move to defend the man if he is attacked
