Uri

DC14 Strength save vs Wolf (prone if fail): 22
Constitution save vs thunderwave: 13 (unknown DC)
Total damage 29 hp

If he fails the Con save and is knocked off, he has Slow Fall (PHB, pg. 78): You can use your reaction when you fall to reduce any falling damage you take by 55.

(How far does he fall? Also, does the wolf get knocked off too?)

Dench tries to twist his way out of the winter wolf's frozen breath: 10, but stumbles instead.

He does not like the cold and casts Sacred Flame on the wolf: Dex DC of 16 (-1d4 due to Bane) for 16 damage.

Then, he reacts to the bear woman's rage against Gadston, by channeling some of Lathander's divinity to him, granting him a +10 bonus to his sword attack. 

Gadston swings wide but Lathander's holy light guides his sword toward the target. Then he catches the bear woman with his fist.

Direcris again plagues the wolf in back with necrotic energy. The Large creature's form is visibly wilting.

Uri is tripped and then forced over the edge. He rapidly falls to the rocks and water, but his training saves him from the precarious fall.
(-20 bludgeoning damage, ignoring negatives)
(The wolf seemed to be outside the blast)

Dench summons radiant flame down on the forward wolf.
(DEX Save v Sacred Flame, 11)

Gavyn dodges in preparation for the next attack.

The front wolf engages Gadston with the bear woman.
(Bite v Gadston, 17 to hit, 11 piercing damage, on a hit Gadston must succeed on a DC 14 Strength saving throw or be knocked prone.)
(Greataxe v Gadston, 14 to hit, 11 slashing damage, attacks against her have advantage this turn) (11 to hit if prone)

The wolf in the back cannot make it around the narrow passage to attack one of the group. They Dodge, ready for another attack.

The mud woman sprouts a mess of plants and vines behind the 'camp', casting entangle. 
(Dench, Direcris, Gavyn, and Gadston must make DC 12 Strength saving throws. On a failed save, you are restrained.

(Damage so far: Back Wolf 40 bloody, Bear Woman 18)

Uri

Uri doggedly attempts to scale the side of the ravine, knowing that the bandits would be unlikely to expect him to have survived such a fall, never mind climb up so quickly. Drawing upon his inner ki, he virtually runs up the cliff face (bonus action dash). On reaching the path he crouches, anticipating any further attack (dodge).

(7/11 ki)

Thick, twisted vines sprout around Dench. He flexes against them: 14 and they do not restrain him.

Ignoring the muddy woman, he points at the wounded bear woman, urging her toward the night dawn requires. A dolorous ringing fills the air as he casts Toll the Dead: WIS DC 16 (-1d4 for Bane) for 27 damage.

Sir Gadston

Str Save: 16

Gadston will attack the bear woman with his sword:

1st strike-Hit: 24           Damage: 12

2nd Strike-Hit: 13          Damage: 7

Direcris: STR save - 5 (I have advantage on spells cast by creatures within 5 ft of me, so if she is - 15)

 (anyway)

Direcris struggles against the vines, trying to cast Chill Touch again on the back wolf. He curses as the vines pull on his arm at the last second. 

Attack: 25 Damage: 10

Uri

Uri beats upon the wolf from the rear, this time ensuring he is in no danger of being pushed off the edge:

Unarmed strike (1/2): 25 Damage: 11
Unarmed strike (2/2): 17 Damage: 12 
Unarmed strike (BA): 21 Damage: 12 

Gavyn strength save: 22

Gavyn pulls free of the grasping vines, takes a deep breath, and sends two precision shots at the bear lady (sharpshooter):

Attack: 11 Damage: 20

Attack: 10 Damage: 22

(I will assume Uri's second turn is for the upcoming round)

Uri rockets back to the path above and prepares for another attack.

The bear woman attempts resist Dench's calls to death.
(WIS Save v Toll the Dead, 18)

Gadston lands two heavy blows against the bear woman with his sword.

The vines pull Direcris down, preventing him from aiming his spell. The necrotic energy strikes the mountainside.

Gavyn peeks out from cover and fires on the bear woman. The first misses, but the second fells the attacker.

Seeing the woman go down, and the wolf going after Gadston, Gavyn turns his attention to it, swiftly loosing two more arrows and aiming for vital organs:

Attack: 19 Damage: 16

Attack: 21 Damage: 17

(Uri ascended previous round, attacks should be before the wolf as far as I can tell)

(Assuming wolf survived his punches), he deftly avoids the wolf’s attack. 

(Buxton is right. So the wolf would have attacked instead of dodging the round before, and Uri would do exactly enough damage to fell the back wolf last round)

 Direcris makes an attempt to free himself. STR check: 3

The area is filled with trilingual curses. He keeps close eye on the other party, trying to gauge when would be the best time to let loose his breath.

Sir Gadston

The wolf attempts to bite him but, it does not penetrate his armor (AC: 18)

Gadston will strike at the woman then the wolf:

Attack on Woman: Hit: 11     Damage: 10

Attack on Wolf:    Hit: 23     Damage: 12

Uri runs up and attacks the mud woman from behind, rage from her earlier thunder attack fuelling his long-limbed blows. 

Attack: 17 Damage: 12

Attack: 22 Damage: 9

Attack: 28 Damage: 8

(After attacking he backs away, able to do so without incurring opportunity attacks due to 10’ reach. If the woman falls before the final blow, he will strike the wolf instead)

Gavyn sinks both arrows into the lone wolf as it dodges sir Gadston's first blow, though the second connects.

Direcris struggles to free himself but is unable to; until the vines suddenly wither away as Uri fells the spellcaster with three rapid strikes.

The wolf, now alone, exhales another icy blast at the group in front of it before turning to run. Getting as far as the soaking wet bugbear.
(Dench, Direcris, and Gadston must make a DC 12 Dexterity saving throw, taking 25 cold damage on a failed save, or half as much damage on a successful one.)
(Gadston can make an attack of opportunity)

Dench tries to roll out of the way of the wolf's breath: 15, but fails to do so.
