Soar grins and presses her attack on the black spider, nodding to Jalt on the opposite side. 

Attack: 19 Damage: 10
Extra Attack: 25 Damage: 9

SG damage roll: 18

Jalt nods to Soar and swings at the black spider with the staff Attack: 9 Damage: 8 if the black spider is down he will attack the next closest spider

Soar's first attack kills the black spider creature; the ghostly knife fades.

She redirects her second attack onto the nearby Spider D. I can't see the dice rolls, so I'll assume that the first dice is enough to hit. It's enough to kill Spider D as well.

Spider F WIS save: 17

Spider F saves and takes the damage, but is still up. It attacks Bazavur:
Attack: 22 Damage: 11

Missing.

(Also, Jalt's attack above missed, but you probably guessed that!)

The phase spider that vanished does not return.

Round Eleven
Tangle and Bazavur 
Soar and Jalt
Phase Spiders
Giant Spiders

Tangle and Bazavur are up.

Bazavur attacks the single remaining enemy with his battleaxe:

Attack: 13 Damage: 10
Attack: 11 Damage: 9

And it dies.

There's no sight or sound of the other phase spider, unless you want to attempt to give chase in some way.

Otherwise, combat is over.

Tangle puts up her bow, plucks her sword from where she stabbed it into the ground, and approaches the dead black spider, poking it with the tip of her saber. “This is a disturbing creature,” she says.

Tangle, the corpse is fresh, the black blood still flowing. The creature is strange; a spider with humanoid hands and a generally monstrous appearance. It doesn't appear to be wearing or carrying anything useful.

"It wove spells, and seemed to command these others, so it was intelligent, but I cannot fathom any way in which it could be connected to our dragon quarry.  Given this organization, however, it may be that it has a mate. We should leave as quickly as we can."

Tangle will prepare to move on as soon as the party is ready.

Soar takes a closer look at the red crystals that were embedded in the spider after she catches her breath. She relies on the others to keep an eye out on the surrounding area…

Soar, make an Arcana check as you inspect the crystals.

Tangle is keeping an eye on the surrounding area, and sees no sign of approaching danger - yet.

Soarcana: 6

The crystals look strange, alien somehow. There's no doubt they are, or were, magical, though whatever magic flowed through them ended with the creature's death. A mix of divine and arcane magic, and something you feel to be very evil. You could recover some of the crystals, or all if you took the time, and perhaps a scholar could tell you more.

Soar tries to pry one crystal out of the spider, and puts it in the bag of holding.

She looks up at the group. "This is the path the cultists took? We sure about that? Either they're allies of these spiders here, or it's been a while since they moved through here. Lots of webs. I think we're a little out of our element. We could use every asset, every blessing, every gift we have." She looks at Tangle and removes the second garland she's been carrying and holds it out to her. "A good friend of mine once said, maybe the grass is listening. Maybe the Caretaker wanted to help guide the way."

Whatever Tangle decides, Soar asks the group if they're in need of a short rest, and where they should go from here. She calls Candelabra and asks him to loop around, trying to avoid the webs.

Soar gets a red crystal. Please add 'Red Choldrith Crystal' to your equipment list. :)

Looking around at the party’s situation, Tangle accepts the garland without further comment.

:)

Then she begins casting about for the cultist’s trail, hoping we have not lost it in the fight and the webs.

Survival: 13 

Tangle sees the trail very clearly, passing through this area and seemingly not disturbed by any spider attacks - for what reason, she cannot be sure. But if you wish to resume your previous journey, you can do so.

"Shall we move away from the webbing, and then take a breather, then?" Soar says, sending Candelabra forward about 50 feet ahead of the group to flag anything notable

Tangle nods assent, and moves after Candelabra.
