(In this case I'd go off of initiative order, which unfortunately means Wendigo would be healed after his turn.  21 vs. 20 initiative.)

Miles:

With Wendigo going down, Miles steps up to face the remaining wererats and protect his comrade while he is vulnerable.

Gasping as she saw Wendigo go down, Vera shifted from her current target to the one who had downed him and attempted to take them down before they could finish Wendigo off once and for all!

• Attack (the one who knocked down Wendigo): Hit- 16/ Damage- 9 Slashing + 3 Sneak Attack Damage
• Bonus Action: Disengage from current enemy (if necessary)
• Movement: Move towards the wererat who attacked Wendigo.

Jhazaal and Vera down the second to last rat, and the remaining rat turns in a desperate frenzy on Vera.

Attack: 15 Damage: 7

Attack: 5 Damage: 4

(Everyone is up)

"We're almost through!" Vera shouted as she pounced on the last wererat.

• Attack: Hit- 10/ Damage- 12 Slashing + 4 Sneak Attack Damage

Jhazaal tries to aid in taking down the final rat. If it goes down he would cast healing spirit for anyone injured to fill up their HP on, outside of combat.

Thorn whip attack:
To hit: 12 Damage: 3

Miles:

Converging on the last rat, Miles adds his own attack to the frenzy of others.

Rolling Pin:  Attack: 9 Damage: 7

Staggering to his feet, Wendigo spits out a gobbet of blood and stares up at the remaining wererat with bloodshot eyes. His ivory fur matted and stained with blood, his face battered, bloodied, and bruised, he practically looks like a demon himself. He goes down on all fours, staining the ground with his blood-slick hands, and leaps at the wererat, bellowing a dreadful howl. Spittle and blood flies from his open maw, ringed with crooked, yellowed teeth. In this state, it's clear that Wendigo is more beast than man. He has truly become the White Wendigo. Well, red, mostly.

Attack: 6 Damage: 9

Attack: 23 Damage: 5

Only Wendigo manages to land a hit, though even with his blood rage they aren't particularly hard ones.

The wererat shies back slightly from Wendigo, then tries to batter him down once more.

Attack: 17 Damage: 5

Attack: 11 Damage: 8

(Everyone is up)

Miles:

Crowding around the last foe, Miles continues to batter against it with his rolling pin!

Attack: 25 Damage: 12

Jhazaal will send another thorn whip in... 17 to hit, 5 damage. If anyone has gone down he will also cast healing word healing them for 5 hp. He will not cast this if no one is down though.

Wendigo staggers, yet stays standing, returning the blow with two more.

Attack: 18 Damage: 5

Attack: 17 Damage: 6

Hoping to finally take it down this time, Vera once again, stabbed at the Wererat with her Rapier.

• Attack: Hit- 12/ Damage- 7 Piercing + 5 Sneak Attack

The last wererat finally crumples to the ground.

(You are out of combat.)

Miles:

Dropping his rolling pin once the last rat falls, Miles pulls out his Greater Healing potion and hands it to the bloodied Wendigo.  “Drink this,” he urges.

OOC: 4d4+4 healing

Jhazaal already stated he was casting healing spirit, why waist a greater healing potion?

On high alert and keeping her Rapier out, Vera scanned the area for any sort of traps or approaching enemies up ahead.  (Assuming the coast was clear) Vera sheathed her Rapier and began rummaging through the pockets of the fallen Wererats, hoping to find information that could aid them moving forward.

• Perception: 14  
• Investigation: 4 :'(

Vera, you don't find much of anything in their pockets.  A few broken pieces of twine, other random objects, nothing really of value.

Wendigo/Miles/Jhazaal you can resolve whatever healing you're doing.

Jhazaal will not cast the spell if potions are being handed out. Doesn't seem like we have a lot of people needing healing, just one, so, with the potion bottle already in play, Jhazaal would not cast any spells.

Miles:

Frozen in time, the good-natured chef holds out the powerful potion of healing to the wounded Wendigo…Will he take it, refuse it, or do something else quite unexpected?
