Out of Character: , That's not as bad as I feared, but just in case. Also, I haven't been recording charges on the rod of magic missiles since I don't know how many it started with.
In Character: Durgan heals Sessativa as she keeps blasting her way towards the corridor. He follows, attacking with mace.
As you continue to fight towards the door the spiders keep pressing the attack. Only three of the dogs saved so the other attacks that hit on the dogs will take 4 damage each.
Round five, Zork hits to spider in front for 4 damage, Only one dag hits this round causing 2 damage. Sessativa hits for 4 damage as Durgan heals her for 6 points. The spiders attack two of them biting dogs while a third bites Durgan. The dogs one take one point of damage while the other takes 2 points. Need saving throws, Durgan takes 3 damage need saving throw.
Round six, Zork hits for 10 damage, the dogs all miss, Durgan hits for 4 damage killing the spider. Only one left before you get into the corridor. Sessativa hits for 2 damage killing the spider leaving the way clear for you to get into the corridor. The spiders attack only one hits and it bites Zork for 3 damage. Roll saving throw Zork.
Round seven you make it into the corridor with the dogs following behind and the spiders coming in behind them. Two spiders at a time can fit through the doorway. Sessativa throws a magic missile behind her as you gain the passageway causing 2 damage killing a spider, Zork hits the one that bite him for 9 damage killing it. The dogs missed again as does Durgan. The spiders attack the dogs as they are between you and the spiders. They miss the dogs.
Round eight. Zork misses as he is out of position as does Durgan. The dogs miss their attacks. Sessativa uses another magic missle and the wand crumbles to dusk causing 4 damage to a spider. The spiders attack only one hits causing 3 damage to a dog. Need a saving throw for the dog.
Looking out you see there looks to be only four spiders left.
"Dammit!" Sessativa sighs as he take up her quarterstaff. Their roles reversed, Sessativa hits spiders in melee while Durgan walks back a few feet. Since the dogs are in the way, Durgan uses his helm's passive ability, thinking of flame in his hand as he says "Blink!". He begins hurling these flames at the spiders as they reappear in his hands, hoping to catch their hair alight or dazzle their many eyes.
Out of Character: That's a Produce Flame, which has unspecified damage in this edition (If any).
Out of Character: Okay, I see. I was thinking more along the lines of the 3.5 edition spell. Durgan will try to make it smaller, to avoid engulfing the desk and bookshelves.
In Character: "Where are these things coming from!" he shouts while continuing to swing his big axe and yelling "Attack!" to his dogs.
Zork you saved thus no additional damage. The first three dogs did not save and take 4 damage to one, 2 damage to a second and 3 damage to the third. The fourth one saved so no additional damage.
Zork and the dogs attack the spiders. The just inside the door way soon are dispatched by Zork's 11 damage and the dogs 10 points of damage. Sessativa steps up and smacks the dead spider with her quarter staff. Two more spiders move forward to attack. Each biting into a dog. 4 damage to one 5 damage to another. Saving throws needed. Durgans flame does an additional 4 damage to the two spiders coming to attack.
Round ten Zork hits the spider to the right killing it while the dogs bite the spider to the left for a total of nine damage thus finishing it off. You do not see any other spiders coming towards you.
