Reuniting the Band

Erbert has his faithful hound join him before he makes this action.  Erbert's shatter when the wall of force is dropped is cast at 2nd level, and does 21 points of thunder damage, with a DC 18 con save to take half of that.  The blast radius includes the machinery (see blue circle), as Erbert tries to destroy their wicked Rube Goldberg machine.  

Move with dash to SE- same direction as the bard

Not sure where my token went on  Owlbear

The kaorti had been looking like they were trying to repair the leaks from the central structure.  On Erbert's arrival, they discontinued and began to leave the room.  Starkie and Erbert engage in the 'Tandem Mage Hokey-Pokey' after dismissing the Wall of Force.  The arcing bolts of magical energy immediately fill the chamber again and extend into the NW corridor.  Erbert is struck for 6 Lightning damage.

Starker's Chromatic Orb flies wide of the target.  Erbert's Shatter spell erupts, echoing throughout the caverns.  The kaorti make CON saves = 21 and 22.  Both take 10 Thunder damage.  The column of fluid takes 21 damage from the noisy eruption.  

Several pipes burst, lurching from their fittings into the central tank of fluid.  Cracks appear in the tank itself and the fluids stop pumping.  There is a keening wail heard, echoing throughout the caverns.  The lightning dissipates and then stops.

Kragen and Chadwick see nothing coming from the passage on the W side.

Trolkarl and Xymox are greeted by a Thrall and a Kaorti coming into view in the S corridor.

(( Starker, please let me know if you wish to trade initiative results with any other PC. ))

Kaorti8 casts Enemies Abound upon Erbert.  Erbert INT save with Advantage = 11 (11, 11), failure.  Erbert now perceives all around him as enemies and must attack randomly based on anyone he can see.  Kaorti8 then moves.

Thrall7 then attempts to Shove Erbert, STR check = 9.  Erbert DEX check = 13.  Failure.

Trolkarl to act.
