Bazavur attacks the web, slicing with the edge of his battleaxe:

Attack: 9 Damage: 6

Attack: 11 Damage: 10He attacks for a second time:

And manages to free himself. His action is used up, but he is able to move closer, to engage the spiders, raging again as he does so.

Tangle is up.

<<rewind!>>

Tangle draws her sabre, and in a moment of calm, tries to part the web just so…

Move: nope (this is the retcon)
Bonus Action: Steady Aim
Action: attack web with Sabre and Adv (vs Disad = normal). 24 to hit, for 8 damage.

Reaction reserved for Uncanny Dodge 

Tangle slices the web away and frees herself.

Soar and Jalt are up.

Soar grits her teeth and begins to tear into Spider A with Talon. (How many more rounds of shield of faith? It's ten, and she cast it just as things got going, but we never left initiative.)

Attack: 23 Damage: 10
Extra Attack: 29 Damage: 18

On a hit, 1st level divine smite: 13 radiant damage

Realized I misread the spell and it's 10 minutes, not rounds, wowzers. 

Jalt swings at Spider C with the staff Attack: 14 Damage: [roll](if([roll:-1:critical], =0, 1and will use War Priest to swing again

Jalt swings at Spider C with the staff Attack: 9 Damage: 4 and if still up War Priest for another swing Attack: 11 Damage: 3 

Jalt will use Guided Strike to add 10 to the first attack roll.

Soar's first hit is enough to kill Spider A; I assume she redirects her second attack at Spider B.

Jalt wounds Spider C, but only a little.

Spider B bites towards Soar:
Attack: 10 Damage: 12

Spider C towards Jalt:
Attack: 7 Damage: 5

Neither manages to bite onto any flesh. And then... they both fade away into nothing.

Other spiders rush into to replace them, making their attacks:
Spider D on Soar: Attack: 11 Damage: 7
Spider E on Jalt: Attack: 20 Damage: 5
Spider F on Bazavur: Attack: 18 Damage: 10
Spider G on Bazavur: Attack: 14 Damage: 7

Once again, the party manages to avoid any damage.

The black spider attacks Soar with the magical dagger it has summoned:
Attack: 9 Damage: 3

And it also casts a spell. Bazavur, Soar and Jalt, please make CHA saving throws. It's Bane so not a charm effect, and the DC is 12.

Bonus Action: Steady Aim for Advantage
Action: Shoot spider E (the one in front of Jalt) with arrow, Advantage, and Sneak Damage: 12 to hit, for 26 piercing damage

Shoot, I forgot Advantage: here’s the other attack roll… 11
