The Kuo-toa caster moves down to M10.  Its feet slide along the webs a bit too easily.  

(DEX Saving throw: 14 or fall and be restrained by the webs)

Restrained or not, the Kuo-toa caster will cast mass cure wounds centered on i14, healing itself and the Persistent Derro Caster (@D16) for 18 healing.

Then it will move its spiritual weapon next to Beegred (@L8) and attack with it:

• Spiritual Weapon attack: Attack: 7 Damage: 7

The Exciting Kuo-toa continues to attack Orubis:

• Bite: Attack: 22 Damage: 5
• Pincer Staff: Attack: 16 Damage: 3

(Start of a new round.  On a 10 or less, spiders join the fight:  97)

(Thurnir, Orubis, Beegred and Rodolfo's turns, in that order)

Thurnir casts Misty Step to appear next to Skameros and with a touch, heals him for 15hp.

Orubis swings at the Kuo-toa next to him, missing with his mace.  However, the spiritual weapon connects.  On a 25 or less, the Kuo-toa is prone:  4.

(Beegred and Rodolfo's turns)

At the start of Beegred's turn:

• Beegred DEX saving throw vs. DC 14: 20.  Take 7 radiant damage on a fail, or half on a success.

Beegred moves to L9. He was hoping to shoot some arrows, but with the caster moving forwards, best to stab away at the K-T Caster.

• Attack1: 27 Damage: 11
• Attack2: 12 Damage: 10
• Dagger Attack: 9 Damage: 4
• If any of the attacks hit, then the first one will mark the enemy with Favored Foe, and do an additional 2 damage.

The caster doesn't quite avoid being stabbed by Beegred the first time, but deftly dodges the next two.  The stitched on second head on one shoulder takes a hit instead and topples over, hanging by crude cord stitched into the creatures skin.

(DC 10 CON Saving throw to maintain concentration: 5)

(Rodolfo's turn)

Rodolfo shoots more magic missiles, this time ata level 2 - one for each opponent. 3 damage. 

Rodolfo fires a volley of magic missiles which swirl and unerringly make their way around the webs to smash into each of the remaining enemies.

(DC 10 Concentration Saving Throw: 22)

The Persistent Derro Caster casts a spell, which takes effect on itself.  It then moves (to G19) across the webs with the same ease shown by Skameros earlier.  

At the start of Skameros's turn:

• Skameros DEX saving throw (with adv) vs. DC 14: 9.  Take 18 radiant damage on a fail, or half on a success.

(Skameros's turn.  Skameros is prone)

Skameros staggers to his feet a bit and moves away from the evil magic (to like J15?) and dodges.

Skameros gets back on his feet and limps away, wary and prepared to avoid any further attacks.

The Kuo-toa caster carefully circles around Beegred (to K10) and attacks twice with a scepter and once with the spiritual weapon:

• Attack: 10 Damage: 14
• Attack: 25 Damage: 18
• Spiritual Weapon attack: Attack: 16 Damage: 14

The other Kuo-toa stands on its feet and continues to attack Orubis:

The Kuo-toa next to Orubis attacks Orubis twice:

• Bite: Attack: 21 Damage: 4
• Pincer Staff: Attack: 18 Damage: 7

On a 10 or less, giant spiders join the initiative:  91

(Thurnir's turn.  Orubis, Beegred and Rodolfo on deck)

When the Kuo-toa strikes Beegred once with a scepter, the blow is enhanced with a jolt of lighthing.  The shock distracts Beegred, who can't avoid the spiritual weapon, which also hits him:

• On a 25 or less, the web breaks and Beegred falls:  69
• On a 25 or less, the web breaks and Beegred falls:  27

The other Kuo-toa finally succeeds in striking Orubis:

• On a 25 or less, the web breaks and Orubis falls:  65
• On a 25 or less, the web breaks and Orubis falls:  99

Orubis falls off the web he stands on, landing and adhering to another web below.  Orubis is restrained by the web he landed on.  The Kuo-toa then pins Orubis, who becomes grappled by the pincer weapon.

(Thurnir's turn.  Orubis, Beegred and Rodolfo on deck)

Thurnir advances as far as he can towards the Kuo Tia caster,  I don’t think he can get there, but if he can, he will attack:

26 to hit

8 damage

11 crit damage if he can hit)

Orubis keeps exchanging blows with the kuo toa

Mace Attack: 24 Damage: 8 

Spiritual weapon Attack: 9 Damage: 8 

Thurnir ponders the difficulty of travelling the webs and traversing the sphere of flitting spectral fiends and elects to Misty Step next to the Kuo-toa caster.

Thurnir DC 14 DEX Saving throw: 18 - Take 27 necrotic damage on a fail, or half as much on a success.

With one critical blow, Thurnir strikes dead the Kuo-toa caster.

(No more saving throws for the creatures.  Only the Kuo-toa was able to heal)

(I have been corrected, and the Kua-toa next to Orubis had to free itself from the webs and stand up as it's full action last round.  Orubis did not suffer the damage, the webs did not break and he was not grappled)

Orubis attacks the Kuo-toa, landing a blow with his mace, but failing to connect with the spiritual weapon.

(Beegred's turn.  Rodolfo on deck)

(Sorry, I can't update the map at this time.)

Beegred looks at the fallen Kua-toa caster, pats his own chest worried about more injuries, then checks his neck for a heartbeat.
"Thurnir, many thanks, you really saved my ar... backside. I thought I was a goner."
(Beegred got Thurmir's name right this time, which probably surprises both of them.)

Although his supply of arrows is dwindling, these enemies need to be defeated quicker. Since the kua-toa next to Orubis stood up, it gets 2 arrows shot at it.

• Attack1: 26 Damage: Unable to parse dice roll.
• Attack2: 12 Damage: 9
