There will be spoilers. You've been warned.
Party setup tonight was 3 fresh level 1s (Slayer, Cleric, Rogue) and my level 2 Medium. The Cleric and Rogue were both first-time Pathfinder players, but the Cleric was experienced with 3.5 sufficiently to be solid. We had more than enough skills at the table to handle the social pieces, including myself. Nobody particularly excelled at anything (i.e. no mods greater than +8), but we got by. I had Bear seanced.
Combat 1: I handily dispatched the dog with a greataxe charge, then drop the axe to full attack the next round and whiff horribly on all 3 attacks. Rogue drops one humanoid, then convinces the other one to surrender. We delay to see what the last one does, stabilize the downed humanoid, interrogate the standing one and let them on their way. Minor damage, which the Cleric heals using my wand and a channel. Nothing special.
Chase scene: Caught up to the target and grappled him. He kept trying to flee, so we brutalized him with nonlethal, tied him up, and interrogated him with the guard present. Found the sniper nest, took the stuff. Upon seeing the poisoned arrows in the nest, I purchased a tower shield as I assumed I would otherwise be mowed down.
Warehouse: The GM misread the tier adjustment and forgot to remove some traps, so this was misplayed and corrected afterwards, when another table's GM mentioned the adjustment. We successfully disarmed the trap and harvested some Alchemist Fire. Nothing else of note here due to the misplay.
Combat 2: We found them sufficiently early, Rogue failed to hit on the surprise round against them. The enemies proceed to do a whole lot of nothing and we accidentally killed them both due to crits, so we couldn't interrogate.
Boss: Everyone counted as human for this fight. Ow. We opted for a fairly direct approach, with the rogue approaching from the side and the others with the keg. Due to the tower shield, I avoid getting ganked in the surprise round, then proceed to approach with total defense, using cover along the way. Cleric runs under the platform and gets killed due to a crit. Rogue and Slayer throw Alchemist Fire, setting the sniper nest on fire and forcing the boss from it. I approach as the Rogue continues to fire on the boss with her light crossbow. Slayer is knocked out, I finally close to melee, dropping the shield along the way, and whiff a trip attempt. Boss takes a 5', Rapid Shots me and I'm staggered. I manage to knock her out and collapse as a result. Boss bleeds out, Slayer and I stabilize ourselves.
Thoughts
Generally, my rolls were at extremes: either I was 6 and down or 15 and up for everything. At the existing skills/lvl, I had a diverse portfolio of skills and was more than able to assist meaningfully in most situations.
I walked into this scenario with a lot of gold. I hadn't purchased anything since before the prior session. I could have had more gear, but I didn't. Given the scope of the adventure, I don't think this significantly hindered my ability to contribute or adversely affected our survival.
Damage still wasn't much of an issue. I hit reasonably hard and it's going to continue to go up as I get both Power Attack and, in a few levels, Dual Vessel for The Beating's seance boon. If I'm particularly concerned, I pull out the greataxe.
I fulfilled my primary combat role well. I still felt as though I lacked options in combat, but that is a known issue.
