Skameros rushes up and makes two mighty swings.  The creature sidesteps the first, but the follow up swing catches the creature flat footed and the blow causes a myriad of cracks in the stone to radiate out from the impact point.

Another petrified drow (@O12) moves (to N6), picking up a rock on the way.  Seeing Beegred already injured, it throws the stone at him:

• Attack: 7 Damage: 7

(Thurnir is up.  Then Rodolfo and Orubis.)

(Junk roll to make the forum fix itself... 2)

Thurnir  moves to M4, and loads and shoots his crossbow at the one at K5. With hunters mark moved to that one (the other one is a statue again- and the animating force moved to this one, so I’m assuming hunters mark is ok to move here) 

24 to hit

6 damage on hit

plus 3 hunters mark if applicable

Thurnir moves between Skameros and Beegred, transfers his Hunter's Mark and fires a crossbow bolt nearly point blank into the statue in front of Skameros.

(Rodolfo, then Orubis's turns)

Rodolfo moves forward a bit (L2) and shoots his Wand of Viscid Globs at the state on O5. Attack: 24. (charges left 5/7)

Our is conjures a spiritual weapon in the shape of squat shepherd’s crook, targeting K5

Attack: 24 Damage: 10 

Ogremoch's Bane uses it's action to exit the statue (@O5) and occupies another (@P11), then it moves (to P6).

The petrified drow (@H0) moves (to @K2) and attacks Rodolfo twice.

The petrified drow (@I4) moves (to @M3) and attacks Beegred twice.

The petrified drow (@L7) moves (to @N5) and attacks Beegred twice.

vs. Rodolfo:

• Attack: 13 Damage: 3
• Attack: 5 Damage: 4

vs. Beegred:

• Attack: 18 Damage: 4
• Attack: 16 Damage: 5
• Attack: 21 Damage: 4
• Attack: 7 Damage: 7

(Beegred's turn)

Beegred is worried for Rodolfo, but is hopeful that the statues most recent attacks means they have absorbed his recent bad luck. Time to try again.

Transfers Hunter's Mark from the (now) statue to M3, and swings the magic sword.

• Attack1: 12 Damage: 15
• Attack2: 10 Damage: 14

(sigh...I should have a 50% chance to hit. One average roll and six crappy ones so far...)

Beegred transfers Hunter's Mark and continues to land ineffectual blows against the stone bodies of these petrified drow.

The petrified drow (@K5) moves (to @L3) and tries to capitalize on the damage already inflicted to Rodolfo...

• Attack: 17 Damage: 6
• Attack: 12 Damage: 3

(Skameros's turn)

Skameros will turn around to the one at L3 and continue his assault 

[Greataxe: 16 Damage: 16 slashing damage]

[Greataxe: 17 Damage: 15 slashing damage]

And if one of those hits his divine fury will proc for 4 radiant damage.

(should L3 fall - he'll attack M3)

The petrified drow (@N6) moves (to @K3) and closes the gap, forming a wall of stone bodies splitting your party and blocking the exit.  The petrified drow attacks Rodolfo...

• Attack: 16 Damage: 4
• Attack: 18 Damage: 7

(Thurnir then Rodolfo then Orubis's turns)

EDIT:  Forum is being dumb.  Something very wrong with the second attack formula against Rodolfo.  If it doesn't fix itself, then this is the correct attack:

• Attack: 17 Damage: 7

(Sorry missed notifications) 

thurnir drops his bow and draws his rapier - continuing to focus on the one now at L3 which he has hunters mark on..

15 to hit

14 damage

Hunters mark 6 additional damage

12 hit two

7 damage

Plus hunters mark 6 

“Now yer where I wants ye” he says 

(Had a typo in my second attack.  It didn’t change any results)

Rodolfo says, "Oof, that's not great."

He casts haste on himself, uses the additional action to disengage and backs out of the cave all of his 50 feet of movement.

Orubis moves into Rodolfo’s position at L2, casting word of radiance for a DC 14 Con save or K2, K3, L3, and M3 take 6 radiant damage. 

He moves his spiritual weapon to strike N5 

Attack: 24 Damage: 6 

DC 14 CON saving throw (order per Orubis's list in post above):

• 19
• 21
• 19
• 11

Rodolfo disengages and leaves the cavern entirely.  Orubis rushes to fill the space vacated by Rodolfo and a burning radiance explodes out of himself.  Unfortunately it only slightly harms one of the creatures.  The spiritual weapon floats over to one petrified drow and hits it solidly behind the creature's head.

• The petrified drow (@P6) moves (to @O4) and attacks Beegred.
• The petrified drow (@K2) attacks Orubis.
• The petrified drow (@M3) attacks the already injured Beegred.
• The petrified drow (@N5) attacks Beegred.

Attacks vs Beegred:

• Attack: 16 Damage: 8
• Attack: 8 Damage: 6
• Attack: 18 Damage: 5
• Attack: 18 Damage: 8
• Attack: 6 Damage: 5
• Attack: 18 Damage: 6

Attacks vs. Orubis:

• Attack: 9 Damage: 8
• Attack: 5 Damage: 5

(The map is nearly identical.  Rodolfo is replaced by Orubis @L2.  The spiritual weapon moved (to @M5) , but that doesn't matter.  It doesn't occupy any spaces)

(It is Beegred's turn in Round 4)

(Orubis has to make a concentration check, DC 10)

Orubis concentration 15 

Five conc checks: 23 , 5 , 21 , 12 , 4

Beegred draws the dagger and attack with off-hand.

Attack1: 9 Damage: 9

Attack2: 14 Damage: 6

Dagger Attack: 27 Damage: 4

(Edit: Forgot to apply “Lucky”, so rerolling that 2nd attack to-hit. 23 )

(Assuming Beegred continues to attack M3)

Beegred furiously attacks the petrified drow like a whirling dervish and finally manages to strike a damaging blow with his dagger.

The petrified drow (@L3) attacks Thurnir...

• Attack: 22 Damage: 4
• Attack: 22 Damage: 3

(Thurnir has to make 2 concentration checks.  Skameros's turn)

Assuming it's still there Skameros will continue to attack the same statue

[Greataxe: 13 Damage: 18 slashing damage]

[Greataxe: 9 Damage: 18 slashing damage]

And if one of those hits his divine fury will proc for 5 radiant damage.

With a massive blow, Skameros shatters one of the petrified drow statues, then follows up with another massive blow to another (@M3).

The petrified drow (@K3) moves to fill the gap (to @L3) and attacks Skameros twice:

• Attack: 18 Damage: Unable to parse dice roll.
• Attack: 16 Damage: 4

(Thurnir's turn.  Then Rodolfo and Orubis)
