MENACE MANUAL: Kulgara

My players hit the main platform of the excavator yesterday as Hellion threw everything against them including Kulgara, Draigs and the Dark Creeper types.  I played the sound a chainsaw a one round before she turned up.  She was demolishing the party with her attacks until a three move combo killed her outright:

1. Broktha used action surge to pelt Kulgara with 3 grenades bringing her into bloody state 
2. Charisma used magic missile to target the 2 of the 3 grenades on Kulgara’s belt and detonating them (taking out Tufast in the process).  This dropped Kulgara to 40 or so hit points.
3. Then Rikku scored a critical hit AND a sneak attack doing 41 damage taking her out.

Broktha immodestly claimed the chainsword as his own.
