(Worg battle)
Zarbyn hits the goblin hard in the chest. He looks like he will not be on alive much longer (1hp).

Za'chak swings his huge club at his opponent, but the nimble creature is able to dodge the attack. In return, it attacks the big man, (1 damage).

The other goblin attempts to hit Lev, but his armor blocks the blow.

Lira, Zarbyn, Lev. (1 goblin has 1 hp, the other, is doing ok.)

Lira reappears to attack goblin 4.

Action: whip to hit with advantage 12, damage 5

Bonus Action: cunning action hide to the southeast, stealth 27

Nest round:

Vydar grins smugly at the goblin, tilting his head slightly as the mage's own spell flies past his face. Finally, he's actually doing something. Keeping his hand raised, he maintains the stream of electricity intending to electrify the mage to death. (Action is maintaining Witch bolt, no attack roll needed)

Damage: 12

Morric was dreaming of cookies, so good. His dwarven friend Ivan made them the best. He had secret ingredient that he refused to divulge to anyone. The. He heard his mother saying, “ Morric, you have work to do..dont be a shirker..”

He opened his eyes as the dryads light faded nasty gashes on his chest and neck closed up a bit and he got himself to his feet. He felt as if he was out for hours, but the rat-beast wasnt far away, its entrails following behind it as it moved against the beautiful trees on the Island.

Morric will run to the edge of the river best he can and hurl a javelin at the rat-beast’s (1) spine figuring it cant take too much more.

attack: 17 to hit and dmg: 9

Vydars magic continues to harm the caster (he's at 17/45hp). He looks to be struggling to keep his spell up but manages.
Off to the east, Vydar hears the battle of warriors against other fowl rat-ogre creatures. His mission is clear. Take out this caster.

Morric's Javelin pierces his fleeing foe. Slowed by the water, the Javelin penetrates its back, piercing its small heart. It falls into the water, its life leaving its maddened eyes.

---->Amdaeng,  Iólinder, Morric has been partially healed, RO 2 is attacking the tree, a swarm of rats attacks Amdaeng and Baatar, Vydar is fighting a goblin caster)

As a bonus action Zarbyn reforms the ebony blade in his hand and uses his action to attack the goblin, 17 to hit for 11 psychic damage.

Zarbyn and Lira finish off the two remaining goblins. The field of snow is covered in blood. Za'chak looks at the group, "We must get to Tseren quickly and decide what to do about triggering the avalanche to block the valley below. Come, he should be right up ahead." 

It is a dark night, but the moon is out for some light.

Iólinder had to make a decision. He knew from experience that enemy spellcasters can pose the biggest danger on the battlefield, thus he agreed with Vydar's actions to take it down quickly. Amdaeng held the island at the moment and the strange person known as Morric got back on his feet after Iólinder could swear he saw the big guy fall down earlier.
He sent his spirit blade towards the little island, cursing the slow hovering of it, and turned his attention to where Vydar headed. The wizard had conjured some sort of lightning arc between him and the goblin caster, making it easy for Iólinder to pick out the target. He joined Vydar in his magical assault with some divine magic of his own.

Bonus action: move spiritual weapon 20 feet towards the island as per the scale on Owlbear

Action: casting Guiding Bolt targeting the goblin spellcaster. Range is 120 feet so that is not a problem.
Attack roll: 23
Damage roll: 14 radiant damage

Lira nods to Za'chak as she tries to catch her breath. "Right, let's...hurry." She steels herself to follow, keeping an eye out for more enemies.

Perception: 17

" Baatar! Get to the tree!"

Amdaeng redoubled her efforts to destroy the rat swarm.

Attack: 24 Damage: 7

Flurry of Blows-

Attack: 23 Damage: 12

Attack: 20 Damage: 8

Morric will dash to make it across the water to see how he can best help the battle.

Zarbyn hurries after Za'chak and Lira.

"C'mon Lev, not much further now!"

The worg tracks came from the direction you are headed. After a few minutes, you begin to crest the peak that looks out on the open valley below. To the north, you see many camp fires of the mixed goblin army below. To the east at the bottom of the ridge is the valley of the Toa-Suo and some of their large Yurts can be seen with fires as well.

Then, rounding an outcroping of rocks, Lira spots two bodies lying on the ground ahead. 

Lira gasps quietly and hurries forward to inspect the bodies, looking to see if they are friend or foe. If friend she will attempt to provide aid with her Healer's kit.

Medicine: 13

Lira and the group recognize the body of Tseren and a younger Toa-Suo scout that accompanied him. "Tseren, Trabik!" Za'chack says as they approach.

It is clear they are both dead, having been attacked by the group of worgs and riders at the top of the ridge.

Tears spring to Lira's green eyes as she realizes nothing can be done. She stays kneeling next to Tseren for a few moments before forcing herself to stand. "W-we...still have a job to do. How do we do it?"

As the group looks around, you see what Tseren and Trabik were working on.
They have planted a number of long poles into the deep snow at the top of the ridge. Each is attached to the next with rope. It appears with a bit more work, it could be engineered to trigger an avalanche of snow and rock. Za'chack looks at the group as he takes the necklaces off his friends necks.

"I believe we have three options. One, trigger the avalanche to completely block the valley corridor going to the north, effectively blocking the army from entering this way. Second, wait for the goblin army to enter the entrance to our valley and trigger it, with the hopes of causing them tremendous casualties and blocking the valley. Or third, wait for the elders to tell us what we must do."

(Arrow is your current location)

Amdaeng moves with incredible speed, dispatching the remainder of the rat swarm in a flurry of movements with little rats flying in multiple directions.

Baatar moves to engage the huge standing rat-like behemoth, attacking it with his spear. His spear does not penetrate its thick skin on the first attack, but his second seems to be effective, 9 damage. (Creature has disadvantage on its next attack roll: SAP).

Iólinder's magical bolt hits its mark. Although the goblin looks on the edge of death, the fanatical caster continues his spell (He made his con save). (Advantage on next attack against him). (He is almost dead).

The rat creature ignores Baatar and attacks the central tree again! Its weapons penetrate the bark and damage the wood beneath. A sort of sap drips out from the wounded tree, reminiscent of blood. 16 damage. However, some of the damage seems to disappear. To Amdaeng's surprise, gashes and open wounds appear on Baatar, as the warrior sustains some of the creatures vicious attack. (Warding bond).

The goblin caster, blood spurting from his mouth, utters words of dark magic as he raises his staff and hurls a bolt of black magic at Vydar: (23 to hit, 15 necrotic damage).

To Iólinder's  right, the sounds of battle continue and Vydar can see several more huge creatures being pursued by the mighty Toa-Suo. The creatures are headed toward the glade as well but are still a good 30 seconds away.

Rat ogre battle: --->All PCS can act: Amdaeng, Vydar,  Iólinder, Morric: We have one attacking the tree It is injured and the last spear attack seems to have weakened it. Morric killed one with his javelin in the water.  Iólinder and Vydar are attacking a caster to the north. To your east, a group of Toa-Suo try to stop several more huge rat-ogres as they advance on the groove.
