Kazri moves to where the creatures are coming from. (If necessary, she will take the Dodge action for now)

"I never fought an owlbear, but I know that they are very ferocious creatures." says Krom "I agree with Rhogar, it is better to deal with them now than later." 
The dwarf, chanting an hymn of evocation (Guiding bolt), follows Kazri . Krom's war hammer is charged with white radiant energy ready to be thrown at the first owlbear within sight.

(I am readying a 1st level Guiding bolt to be used against the same owlbear targeted by Rhogar. Attack: 20 Damage: 11 )

As the owlbears approach closer you fan out to make a line.  Chill disappears into the darkness to the side and finds a tree to hide behind. 

Initiative - Chill 20, Chip 19, Kazri 16, Krom 3, Rekuburk 17, Rhogar 12

Monsters - Owlbear 12, Owlbear 2 15

Chill is up

Chill (45/45), Chip (45/45), Rekuburk (81/81), Kazri (67/67), Owlbear 2 (?), Rhogar (48/48), Krom (59/59), Owlbear 1(?)

Chill,  silently and nearly invisible, moved away from the group and found a tree to hide behind. 

Rhogar has said there was a pair of snowy owlbears approaching from the rear but he couldn't see them yet.   He readied his crossbow to fire when one came into sight. 

Attack: 15 Damage: 24

He then would duck back behind the tree. 

Stealth 14

Chill readies his attack

Chip is up

Chill (45/45), Chip (45/45), Rekuburk (81/81), Kazri (67/67), Owlbear 2 (?), Rhogar (48/48), Krom (59/59), Owlbear 1(?)

Chip would Hold his pan flute up to his lips and play a quick tune. His allies would feel a bust of energy (and 8 temp hp) before he takes a breath and plays a different tune as he casts Hypnotic Pattern. Colorful streams of notes flow from his instrument and circle the two creature line an aura borealis...

wis 16 or be charmed and incapacitated with a speed of 0

WIS 1 4, WIS 2 14

For the moment both owlbears see a twisting pattern of colors and become a bit disoriented.

Rekuburk and Kazri are up

Chill (45/45), Chip (45/45), Rekuburk (81/81), Kazri (67/67), Owlbear 2 (?), Rhogar (48/48), Krom (59/59), Owlbear 1(?)

Rekuberk will move up and ready his javelins, throwing one of them at each of the owlbears as he uses Reckless Attack.

Javelin: Attack: 24 Damage: 10

Javelin: Attack: 23 Damage: 10

Kazri instinctively goes to reach for a boomerang, but stops midway. She figures it would be a long shot, even with the light wind. So, she just moves next to Rekuburk, plants her shield to the frozen ground, and takes the Dodge action.

ooc, remember you guys can use your reaction to move your whole movement speed as part of my bonus action I took to give you all temp Hp

(@Wreck: 'preciated, but I have to hold on to my reaction for when the owlbears cross that 65ft range for eldritch blast'n. I assuming I still get that held action)

(OCC: Sorry, I only saw the Hypnotic Pattern. @DM, can I change my action?)

 Yup

Rekuburk rushes forward and when he gets in range of his javelins he quickly throws two of them and each strikes one of the owlbears.

Kazri is up

Chill (45/45), Chip (45/45), Rekuburk (81/81), Kazri (67/67), Owlbear 2 (10), Rhogar (48/48), Krom (59/59), Owlbear 1(10)

Kazri moves next to Rekuburk and throws Firebeard’s Fist to the closest owlbear. (I am assuming the target is 20ft from Kazri.)

Light Hammer Attack: 13 Damage: 6

Kazri tries to keep up with Rekuburk but he outpaces her.  She is still able to get into range of her light hammer though and throws it and it strikes the nearest owlbear.

The closest owlbear, no longer charmed due to having been attacked, launches forward and claws and bites at Rekuburk

Beak Attack: 17 Damage: 12 piercing

Claw Attack: 11 Damage: 13 slashing

The owlbear clamps its beak down on Rekuburk and blood flows from his arm.

Rhogar is up

Chill (45/45+8), Chip (45/45), Rekuburk (78/81), Kazri (67/67+8), Owlbear 2 (10), Rhogar (48/48+8), Krom (59/59+8), Owlbear 1(16)

As the creature's don't quite make it into his range first(?), Rhogar abandons his spell in favor of striding a few feet closer, then jab and drawing with his staff a burning, circular sigil. At its completion, he calls out  "Ergramos!" while striking through the sigil, dissipating it. Moments later, a bead of white flames appears to the north of the nearest bear from nothing, before then abruptly grows into sphere easily the size of a short human. And with but a flick of an ivory staff, it rams at the bear with deadly intent, evaporating bits of snow along the ground.

Movement: 10ft closest to nearest bear.

Action: Cast (2nd level)Sun's Wrath, summoning it just north of Owlbear(1).

Bonus Action: Ram Sphere into Owlbear(1), inflicting 7 Fire Damage. Dex Save(DC 15) for 1/2 damage.

Krom points his war hammer charged with radiant energy at the nearest owlbear. White radiant light streaks towards the creature.
After seeing the effect of his incantation, the dwarf runs towards the owlbears.

Action: Casting the readied Guiding bolt (attack and damage rolls on post #502 20 to hit for 11 radiant damage - advantage on the next attack roll)

Movement: 25ft towards the owlbears
