Phallon sidesteps to his right, and fires his pistol at the shroom (col 8): 80 3 = green hit.  BD14-4AC = 10×2 = 20 points of damage.  It looks not well.

Zeebo readies his bow, and uses telekinesis (col 12): 2 3 = white result.

Arvak smashes it with his hammer (16): 9 5 = orange hit.  BD14-4AC = 10×4 = 40 points of damage.  It is dead and crushed to a pulp.

Ragnor blasts its carcass with his shotgun (col 20): 30 6 = green.  BD18-4AC = 14×2 = 28 points.  Its remains are blown all over the floor and wall.

The hall is full of smoke and your ears are ringing.

Combat is over (for the moment).  Your move…
