(Just as a confirmation, I'm going with my turn the way you described it, no need to change anything.)

Quote from Pertuie >>

 

The owl, under Rellahne's command, distracts the stone statue one more time and flies up and out of its range with Flyby (directly up in the skies, depending on how close the ceiling is),

 

  The ceiling of this hall rises to an apex of twenty feet overhead.

Tyris is up 

Tyris stumbled towards the door as the Ogre shoves it's way into the room, putting a little extra distance bewteen himself and the large creature.  He marks it as his new prey before launching an arrow in it's direction.

Move to above A and left of R
Bonus action: Slayer's Prey on the ogre
Action: Attack: 20 Damage: 10

Tyris' arrow finds it's mark and slams into the orge's chest. 

Shadow is up 

Btw I must roll in order not to loose concentration since I took 14 damage 5

 Yes I didn't realize that hunters mark needed concentration. 

The stone column bashed Oreus pretty hard, and Oreus lost focus on his spell.

Shadow is up 

Shadow sneers "the bigger they are the harder they fall"

Tasha's Hideous Laughter dc 12 wisdom save or fall prone incapacitated with laughter for up to one minute.

Xukasus's Wisdom save 15

Fario turns around and using his bonus action to catch his Second Wind 10. He then maneuver around the Orge (next to the southern hanging cage) and attacks him with his Longsword Attack: 9 Damage: 6, but his sword hits the cage instead. 

Fellian will shoot at the Orge with his Shortbow Attack: 14 Damage: 7, hitting the orge. He then decides to attack it again using his War Priest ability to attack twice, Shortbow Attack: 24 Damage: 9, and the second arrow slams into the orge with a resounding thud.

The Orge is torn between attacking Fario,  and wading further towards the rest of you. (1=Fario, 2=Oreus, 3-4=all the way in) 2. Xukasus decides to attack the paladin standing in front of him and steping forward, he opens his rear to attack. 

Fario's opportunity attack with his Longsword Attack: 17 Damage: 6, this time hitting the large ogre. 

Xukasus attacks Oreus with his Falchion twice. 1st Falchion Attack: 17 Damage: 12, hitting Oreus with the first attack. He follows it up with a 2nd Falchion Attack: 19 Damage: 12, dropping Oreus. Speaking to the party in their mind again he says "That's one, would the rest of you like to surrender, it will be easier on you if you do!"

Oreus give me two Constitution saves and a death save. 

Rellahne, owl, Oreus, Tyris, and Alben are up 

Rellahne keeps her ground and instead of backing down or being intimidated by the menacing ogre, she does quite the opposite. Running in front, she decides to take a risk by pulling a greater potion of healing and giving it to Oreus to wake him up. (16 HP healed). (If there's a spot between Xukasus and Oreus - as the map makes it look like it does, Rellahne would be just between the two, otherwise, she'd be on the spot behind Oreus.)

The owl receives the command this turn to help Oreus attack the ogre once he's awake and then flyby out of its range into the air.

 No the orge moved that 5 feet.

Oreus you can act as well, but you still need to make the to Con saves. Don't forget that you can attack with advantage because of the Owl's help.

Alben will cast magic missile at the ogre: 26+26+29

(oops, my bad) 2+5+2

Alben's Magic Missiles answer the telepathic message as they burn into the Orge. 

Tyris and Oreus are up 

Con save 20

Con save 13

Oreus lost consciousness for some seconds but then he regained it thanks to Rellhane help. 

Back to his feet he sees an owl distracting the ogre 

"I must take this chance"

And attacks the brute

ACTIONS

MOVE to get on his feet

Attack: 26 Damage: 19

Bonus Attack: 17 Damage: 8

Oreus bounces back up and manages to hit the Orge with both his main attack and the butt of his Glaive.

Tyris is up 

Tyris adds his Hunter's Mark to the Ogre and launches another arrow.

Attack: 13 Damage: 14

Tyris is not impressed with tjeorge's mental barb, and to show it, he plants a soild arrow into the orge's off arm.

Shadow is up 

Shadow will draw his short bow and fire at the ogre with sneak attack as there is an ally within 5 feet of the enemy

Attack: 24 Damage: 11
