Another guardsman goes for Rolth. He misses.

A woman in a dark green metal armor walks out of the door far to the right, behind the daemon. She gazes around at the destruction. "It seems things have gotten a little out of hand."

She runs at the daemon. Her hand seethes with eerie dark fire. Slay Living. 

The spell fizzles uselessly against the daemon's spell resistant skin.

The guard's second circle wizard fires a scorching ray through the illusory wall at Rolth. It burns.

The sound of retreating footsteps can be heard from behind the stinking cloud.

The spiritual weapons summoned by the clerics of Pharasma fly at Rolth. One carves into him.

One cleric of Pharasma casts bless, catching the lantern archons in its radius. The other flings an icicle at Rolth. It cuts him a little.

A guardsmen charges at Rolth and misses by a mile.

The sound of more retreating footsteps can be heard from behind the stinking cloud!

The third marine follows the second up to the edge of the open door. He fires an arrow at Rolth. Hit!

The marines aren't all in position yet...

A guardsmen runs up to Rolth and slices him open.

He wavers for a moment before collapsing to the ground.

The sound of even more retreating footsteps can be heard from behind the stinking cloud!

The fourth marine follows the third up to the edge of the open door.

The cleric of Sarenrae runs up to the marines and casts align weapon on their arrows.

Guess what the cultists behind the stinking cloud are going to do. If you guessed "more running away" you would be correct!

The guard's third circle wizard doesn't want to waste spells on the demon (daemon?) unless he has to. Spell resistance is hard.

The guard captain doesn't want to get into melee with a demon if he doesn't have to! He'll wait for a good moment, in case an opportunity opens...

Everyone who saw the illusion cast is dead, and nobody announced its existence like last time. Even better, the cleric just heard their wizard call out that a Wall of Stone was present. She'll believe another one. The daemon seems to be happily attacking the cleric, the cleric the daemon... as Ulon teaches, the best way to fight a three-sided battle is to let the other two sides do it for you. Who knows not of your presence harms you not.

"Blocking them off! Let's retreat and let them fight!" Silent Image, a Wall of Stone over the door out of the daemon's room. The shadow can stay here to watch, and alert her if anything happens. It can see through her illusions just fine, because it can sense their falsity.

Behind the illusory stone wall, the daemon turns to face Andaisin. It bites and claws into her. She screams.

FEAR ME, MORTALS!

A zombie wanders in through the stinking cloud.

The first marine puts two non-aligned arrows through its head. It dies instantly.

Fine. Andaisin swings at the daemon with her scythe. It seems to damage both her and the daemon, but the daemon worse.

A second zombie wanders in through the stinking cloud.

The second marine puts two non-aligned arrows through its chest. It's still alive... barely.
