Blackpowder Courtesy
Head to the docks and inside the Qunari compound. Talk to the Arishok and he'll inform you that Javaris has stolen poison in an attempt to acquire black powder explosives. Head to Darktown and talk to Barker to discover that Javaris went through the Smuggler's Cut.
Take the passage to the Cut and you'll do battle with tons of dwarven Carta members. They are resistance to most magic, but can still be taken out with ice and nature type spells. Clear out the cave and exit out to fight another mild battle against more mercenaries. With his guards dead, confront Javaris. There is no reason to keep him alive, so feel free to stab him in the back.
Return back to Kirkwall and stock up on healing items. Travel to the Side Alley and do battle with more waves of mercenaries. There will be poison gas flowing, but it does very little damage, even while in battle. Collect Steel Latches from the ground and off enemy leaders to seal all of the poison barrels. You'll finally fight one last wave lead by a crazed Elven Warrior. Be sure to loot her corpse and steal her Two-Handed sword for one of your own teammates.
