Boozy Jon moves to N2 and fires at the Ogre 

Plink!: 24 Damage: 11

Then he will Hide Stealth 25

Barrington nods to Iarus, then heads up to I10 and attacks with his longsword. 

Attack: 18

Dmg: 10

Gilrosh takes up a position at L12 and throws a magic stone at the Ogre with the accuracy of the wild.

"You were not meant to be!", the dwarf cries.

Attack Attack: 13 Damage: 4

Tenacity attacks with her short bow but is unable to hit so focus on helping her ally focus.

Boozy Jon moves like a whip shooting and disappearing again. 

Barrington strides forward and makes a swing at the ogre.

Gilrosh launches a magic imbued rock at the ogre though it barely feels the hit. 

Group 2 your up!

Iarus will shift himself next to the ogre (wherever he can, can't quite see on the map) and cast bless on himself, Barrington and Boozy Jon (if he's in range).

The creature was BIG. Bigger than any Elwin had fought so far. He could still feel his patron's magic surrounding him, flowing through him and assisting him... but he decided he needed more. The sooner the creature was felled, the better.

As Iarus moved, he quickly clasped his crystal again and whispered another curse, a more formal-feeling one, as he motioned with his fist toward the monster. He felt a surge of magical energy, and knew he'd reached his limit, but that the spell had been cast. Dropping the crystal, he lunged forward and struck toward the ogre with a growl.

Elwin remains at J9, using his bonus action to cast Hex at level 1, targeting the ogre and it's Strength. He then uses his action to attack the creature with his spear.

Spear Attack: 23, Damage: 14

Zashier stops staggering after a few moments, and clutched at his arm hanging nearly limply at his side. "Don't... *cough*… Don't get hit by that." Says Captain Obvious as he fished around his person for his kit. One diluted potion and a few quick wrapped and splinted bandages later, a more stable Zashier began bouncing lightly on his feet as if read to jump aside of any follow-up attacks at a moment's notice. 

Action: Healer's Healing on Self for 7 HP regained. 

Bonus Action: Patient Defense - Dodge option. 

Thargan will move to I7 and take 2 swipes with his shortswords.

Attack: 8 Damage: 7
Offhand Attack: 18 Damage: 10

 I already gave Iarus Bardic Inspiration

(That has nothing to do with bless.  Bless is semi-permanent, Bardic is one use.)

 You're right. That was my bad. 

(You’re fine.  Some casters don’t bless themselves, but I have horrible luck on concentration checks so I always do.)

Iarus calls upon a blessing from his deity and moves in closer to the ogre ready to strike.

Elwin brings black shadows around the ogre being able to focus on it.

Zashier binds his wounds quickly and takes a defensive stance.

Thargan swings twice quickly at the ogre.

The Ogre leans back from all the hits it receives and focuses on Thargan. 1

The smaller head on the ogre seems to take control of it and the ogre points behind Elwin and casts  Shatter I need Zashier, Elwin, Iarus and Thargan to make con saves. To beat 14 or take 19 Thunder damage or half on a save. New roll: 11

Zashier's Con Save(DC 14): 17.

Iarus Con save: 9(2)

Concentration: 14(3)

Thargan's Con save: 20
Concentration save for hunter's mark (DC10): 14

 (Though I don't think I was in the area, I moved in my post and the map wasn't updated with my new position so if I am in range, the ogre should damage itself as well) 

Elwin steels himself against the thunderous assault.

CON Save (DC 14) to reduce damage: 12
CON Save (DC 10) to keep concentration: 21

Total HP loss: 5 temp HP + 6 HP => 11/17 HP remaining
Elwin's protective frost is completely blown off by the attack, but he manages to maintain his hex.

Tenacity will move up to H14 and will cast Bane on the Ogre (DC 13)

Barrington Bigsby attacks once again!

The other head knows spells? What kind of abomination?

Attack: 7 Damage: 8

Gonna pop a Devine Smite on that. Another 6 damage.
