Murdering some player characters Pathfinder

So last night my players were investigating/assaulting this fort, which as far as they can tell is empty. Its got some spriggans hidding around in it with a bunch of wolves and the walls are wooden pallisades with caltrops nailed into the top to discourage climbing. Our party gunslinger just about killed himself trying to get over the gate. But they had a folding boat they used as a ramp to walk up, pretty good idea. Anyways they get out into the courtyard, all 7 of them, and get ambushed by two encounters, one with 2 spriggans and another with 2 spriggans and 8 wolves. Of course, the group of 2 botched their hide roll and the others did great and got the suprise round on the party. It was a great fight, could have gone either ways for a couple of rounds, the pc oracle was blasting out channel energy, the bard was throwing glitterdust, and the pair of arcane pcs were tossing magic missles. The barbarian king and the paladin were jumping around disarming and disemboweling the spriggans, a fun time for all! Towards the end of the fight, which was fairly bloody, they start taking boulders from another spriggan in the window of a castle and the party scatters a bit. The sorcerer goes running up since the spriggan was on floor 2 and gets nailed with a boulder, falls in a covered pit trap, and gets stabbified by a lot of spikes. Shortly thereafter the party runs up and ranged attacks the dood down and has some laughs about the skewered sorcerer... who survived at -7 hp somehow, definitely not pulling any punches with a 7 pc party.

big ass thumbs up! Sounds like some of the player's dice went pretty cold. Also sounds like yall had a lot of fun!

Wish me luck were going back into the worlds largest dungeon (pathfinder style) today, hopefully we can have as interesting a fight as that!
