I've had a few fun and interesting encounters with my players too.
Interrogations after the Raid:
My players decided to go to the barracks, and convinced Hemlock to let them interrogate one of the goblins. The arcanist used illusions to make an image of one of the goblins they killed try to talk info out of one of the captive. Rolling crits on bluff, they squeezed out info by tricking the goblin into believing that he was telling a friend.
Thistletop:
With the use of Charm person/monster, Illusions, Ghost sounds, really high bluff rolls, and really low goblin sense motive rolls, they managed to convince the goblins that one of them is a goblin fire god. They convinced just about every single goblin other than 2, that they have come to help them. They even convinced them that invaders from earlier that took out gogmurt (because they raised the alarm) were killed by them.
The two goblins I spoke of that didn't believe were killed by the "fire god" with a kinetic fire blast with the gunslinger hidden behind them, shooting his gun at the same time criting them for 4x damage... Because of the loud gunshot and that the gunslinger was out of sight, all the goblins saw was the fire deity smite the unbeliever with fire and a loud bang of noise. They did this twice in two different rooms, one of which being in front of the Warchief.
Book 2 they didn't do anything majorly out of the ordinary.
Turtleback Ferry
After discovering the rune on people, the local arcanist made a couple wands of erase, and spread word about discreet tattoo removal. He spent a couple of days just going through the town, spreading rumors quickly and investigating people, removing half the town's tattoos well before the flood.
Down Comes the Rain: Black Magga
The party arcanist cast slowing and rooting spells constantly on the magga, causing it to be unable to move at all (any and all attempts were met with really low rolls). The Magga was able to kill the Magus, but the party was able to kill the Black Magga, which is a major feat as I over doubled it's health.
They are currently about to explore the Hook Mountain Clanhold. I can update on any future ventures later :)
