As soon as Betsy alerts him to the incoming threat Flynt wastes no time moving across the room (B2) and firing a couple bolts at the ogre. On his way to his new location he enables his "Giants Might"(bonus action)

Attack: 22 Damage: 6

Attack: 11 Damage: 20

If one of the attacks hits giant's might causes it to deal an additional 3 damage

(Miscounted. Make it B3.)

Round 2

Flynt moves and takes position across the room from the Ogre.  Both of his shots manage to hit.  (Note - damage of 10 on the last roll, should be 6+4 instead of adding 14!)

(Elyria is now up.) 

Elyria quickly moves to get a clear shot at the raging ogre (B2) takes aim and fires an arrow from her elven longbow.
Elven Longbow: 23 Piercing: 9

Round 2

Flynt moves and takes position across the room from the Ogre.  Both of his shots manage to hit.  (Note - damage of 10 on the last roll, should be 6+4 instead of adding 14!)

(Elyria is now up.) 

 (14 is right. I kept his +9 to hit bonus on the first on to insure the hit and used sharpshooter feat on the second for damage.)

After blocking the ogre's mighty smash, Aurelius counters with two quick thrusts of his longsword. "I see that your mistress the hag brought someone along even uglier than herself.  That is no small feat, monsieur, you should be proud!"

First longsword Attack: 20 Damage: 6 magical slashing + 6 fire damage

Second longsword Attack: 22 Damage: 10 magical slashing + 3 fire damage

(Sorry, I will add back the 10 damage from Flynt's attack.)

Round 2

Elyria's shot hits the Ogre as well.

(Aurelius is now up.)

(already went, mate)

(Well, not sure how I missed that. But when I sent that I hadn't seen your post Aurelius!) 

Round 2

Both of Aurelius' blows land soundly against the Ogre. It stagers back a bit, seeming to be heavily wounded.  

Rahkeshi moves away from the Ogre as well (to C5) to get a better view of the monster. Saying an arcane word she casts Mind Sliver at the Ogre. 
(INT Save DC 12: 9, Damage: 8 psychic) 

Suddenly a Fog Cloud fills the room (filling C1 to F4).  (Vision within and looking through the fog cloud is heavily obscured. Attacks through it are at disadvantage. If you enter, attacks against you are at advantage.)

Then the door to the south bursts open with a loud thud.  Heavy steps enter the room, but only Rahkeshi can see.  
<Unknown> attack against Rahkeshi.

The Ogre again swings its club at Aurelius.
(Greatclub Attack: 26 Damage: Unable to parse dice roll.)

Round 3

To only Aurelius:

(Flynt is now up.) 

Quote from Culuril>>

The Ogre again swings its club at Aurelius.
(Greatclub Attack: 23 Damage: Unable to parse dice roll.)

Re-rolling the Damage for this: 12

Rahkeshi's spell strike the Ogre. (Ogre subtracts 1d4 from next save roll.) 

Map Update (Note - attackers near Rahkeshi and Aurelius are not show but I'd guess the sound would carry to Elyria and Flynt. They can obviously see their attackers.) 

I think it's currently Flynt's turn, then Elyria.

(So sorry.. I checked the thread, meant to post, got distracted by work, forgot to come back.)

If Flynt can see the new attacker he will direct his fire there, if not then he will move south till he can. He makes sure he skirts around the fog. 

Flynt fires three shots at the new arrival,  Using his sharpshooter skills on each.

Attack: 13 Damage: 15

Attack: 20 Damage: 20

Attack: 15 Damage: 18

Realizing new enemies has arrived through the south door, Elyria chants in sylvan to summon her pack of wolves to assail their foes.
Move to A1, then Cast Conjure Animals to summon 8 wolves to appear around her.
Wolf pack initiative: 22

As Flynt steps forward, when he gets to the corner of the room (B5) he can see the Ogre that is attacking Rahkeshi. (Elyria and Aurelius still cannot see this.)  He fires his crossbow at Ogre 2, all three shots hitting and delivering heavy damage.  The large creature is not killed though. 

Elyria moves back into the very corner of the room. She is still unable to see any of the enemies.  She summons 8 wolves that fill in all of the remaining space between her and Flynt. (Each creature must occupy a space you can see. You cannot see into the fog, so they are placed as shown in the map below.) 

(Aurelius is now up!) 

 
Map Update

Wounded gravely and grappled, the paladin roars out, "At last! The guest of dishonor has arrived!  Friends! To me! Leilatha's weakling sister is here, and she is even uglier than her sibling!"

(BA) Aurelius taps the holy symbol embedded on his shield, and casts shield of faith to bolster his defenses. (AC now 25)

(A) He gives a mighty heave to try to break out of the hag's crushing hug.   STR (Athletics) 19

"We're coming brave Aurelius." Elyria calls out in response to the paladin, then turning to her friends from the forest. "Go forth now and hunt down the evil hag and her ogre minions!"

Round 3

Aurelius manages to wrestle his way free of his attacker's grasp. 

Saying a word in Druidic, Rahkeshi casts Shillelagh and then strikes Ogre 2 with her staff. 
(Quarterstaff Attack: 20 Damage: 5)

Ogre 2 swings its club at Rahkeshi again.
(Greatclub Attack: 16 Damage: 17)

(Elyria's Wolves will be next.)
