This Ogre seems larger than usual. Roll initiative

Ogre: 5, 80 HP

(80 health! WHAT the - um, he has 5 initiative, so he probably goes last.)

Initiative 18

The Ogre is stupidly biting a tree right now. Congratulations, Vedar. 21. Current order so far:

• Cunning - 21
• Ogre - 5

Will wait for everyone's initiative.

Cunning sees the ogre approaching and isn't happy at the size of it; if this thing gets an attack in first it could do some serious damage!

He fleetingly wonders if it could be talked to but instantly dismisses the idea; ogres don't talk unless they are seriously overpowered. As a result he calls on his rage and charges at with his maul
Attack: 21 Damage: 8

As a side effect of his rage any party member within 10' receives 2 temporary hit points.

The Ogre is slammed with the maul in the leg, and it lets out a loud yelp of anger.

Ogre has 70/80 health

• Cunning - 21 (did attack already)
• Ogre - 5

(( Titus' Initiative: 10 ))

Jakus’ initiative: 6

Ogre has 70/80 health

• Cunning - 21 (did attack already)
• Titus - 10
• Jakus - 6
• Ogre - 5

Where is everybody at?

Jakus would probably be near the back of the group, behind the fighters.

Init: 9

Ogre has 70/80 health

• Cunning - 21 (did attack already)
• Anasfrya - 21
• Titus - 10
• Thrudor - 9
• Jakus - 6
• Ogre - 5

Initiative: 21

Anasfyra would be a bit closer to the front of the group.  Probably only a bit behind Titus. 

Her first action would be to cast Phantasmal Force, creating an illusion of a dense swarm of bees around the ogre’s head, “stinging” anything on the ogre that they can reach. 

Ogre's investigation: 10

The Ogre takes 6 damage

Ogre has 64/80 health

• Ogre - 5

Titus grimaced. Part of him had hoped the kobolds would be caught misrepresenting the situation, but it didn't seem to be the case. Still, he thought, perhaps they could examine the area for clues--after the creature's rampaging had been stopped.

Seeking to end the conflict quickly, the fighter raced towards the ogre, gripping his blade tight as he angled it low and towards the right. Closing into range, he suddenly hopped to the left as he prepared his swing, then immediately leapt to the right, bringing his sword up at an angle towards the left to slash at the arm holding the creature's club. Not slowing to assess the damage, Titus redoubled his efforts and held fast to his greatsword, using the momentum of the attack to spin, crouching as he did to deliver a low swipe devised to knock the ogre down even as it cut into him.

MOVE: To close in with the ogre
ACTION: Attack with his greatsword; if it hits, will apply Disarming Attack, and the ogre will need to make a DC 13 STR Save to avoid dropping its weapon onto the ground
* Greatsword Slash - Attack: 13, Damage: 17 (add 14 on crit)
EXTRA: Use Action Surge to attack again, this time applying Trip Attack on a hit; the ogre will need to make another DC 13 STR Save to avoid being knocked prone
* Greatsword Slash - Attack: 6, Damage: 15 (add 14 on crit)

End of turn!

Ogre has 37/80 health
