I was afraid the troll would go after Ashley and not Cat. How far can that thing smell?
I see no point in attacking now. The troll is out of Yulya's reach and within the crossbowman's reach. I say we simply do nothing for another turn. Let him go N or NE.

Ashley stays put and send another buzzer south.

Alice moves 10FT West.

[I suppose I know where your tunnels are and will note them personally if it comes up. There's no snow under the trees to tunnel, just so you know.]

Yulya casts SHIELD OF FAITH on Alice to raise her AC

[I am allowing multiple concentration spells though this is technically not Vanilla. Note that if Yulya is hit, she will lose concentration on this spell.]

Cat lays in wait

[This is why I thought surprise should have a free attack and initiative because couldn't you save your turn, but vanilla says no, you can't save up a move from one round to the next, it is forfeit if you take no action on the turn, I will however automatically give you parry so if someone tries to attack you, parry will block it within the damage of your biggest melee weapon for melee attacks, it doesn't apply to ranged attacks. I am also allowing advantage if you retain surprise obviously. I am also guaranteeing initiative, so no roll was necessary. So far you have a good chance not to be spotted though every time you move there's a chance to be seen. They can't see you if you're behind full cover and they can't hear your footsteps because of the blizzard like conditions, they also can't hear the dragon wasps but they will hear anything bigger.]

The wind gust causes any lateral move Beatrice makes to move as much South.

[She made it 25ft North of the Northwest wall corner.]

The hooded crossbowman continues to look out for anyone.

The Troll hears the wasp and moves North instead of following Alice's trail East. He closes the distance, though she's slightly obscured from the crossbowman, the troll is able to swing at her with his crossbow as an 2-size up improvised weapon.
 
[HIT vs AC10 1d20+7=CR][Hidden rolls] The troll easily smashes Beatrice like swatting a fly, she pops out of existence again. He sticks his nose in the air and is able to smell Ashley and Yulya.

[You notice that with his size, the Troll is free to move normally and is not slowed by the snow.]



[This ends Round 2 if no one else has any further moves. Currently you have initiative as default.]

Haa, Kashtan had to give away the big secret. So I might as well tell you everything.
I would have fallen off my chair laughing if Joy had made the troll attack us - only to see it getting maimed in one turn.
Frankly I dunno if it works and you'll probably nerf something after that but yeah, I have 3 attacks but deal 4x damage with Flurry of Blows + Hand of Harm combined for 1 Ki point.
The big gamble is Cat who will put everything in Heavy with her Greatsword. But she needs advantage for that so I flank the Troll and attack from behind.
Ashley will summon Nixie and have her attack. I'm afraid she can't summon her early because that boom would ruin the surprise (or can it work as distraction?) In any case that's not a problem. We have Surprise so even if her first attack is weak, she'll shine in the next round.
The real game-changer is Yulya. She will attack as soon as she notices that the troll is injured and will use her Ring of Quick Casting to cast 2x Toll The Dead and amplify it with her Goblin Staff. That's 2D12+6 necrotic damage. While Cat, Nixie and me have advantage, I think this won't apply to Yulya. Does she have inspiration? That would be a good time to use it.

Well, that's my glorious plan. If the Troll survives the surprise, rinse and repeat. We can uphold that for 3 rounds and only be stronger when Ashley rallies Nixie. Cat needs to take the first hit from the troll and survive. I gain 2D6 hp each round from her Path of the World Tree so I should be good. I think we're a great team with Emboldening Bond and Path of the World Tree combined.

Continued plan - if we manage to down the troll we catch the beastmaster as hostage, then retreat for the night into the Cat igloo some place away. I have one more surprise but it will remain one until it's time.

For now the crucial steps is luring the Troll to where Cat is and where the crossbowman can't shoot us during combat.
And that Ashley summons wasps as distraction and to find the beastmaster. We gotta make sure he doesn't make a run for it.

Something tells me you can't one-shot the troll

prolly not but if Alice is correct we should be able to churn out a theoretical max of ~100dmg in 8 attacks each round without crits. not that i trust Alice in anything regarding numbers

no idea how much hp and what resistance and ac that troll has but i doubt it can take that for more than a few rds. Cat should be able to take one or two attacks with her resistance and additional hp. if we have surprise and only then i think its doable. i also think we shouldnt know the trolls stats beforehand because the girls dont know. Alice Ashley and Yulya have never seen a Troll and i dont think Cat either. shes the only one who knows anythong about monsters at all.

id like to get the beastmaster first but we cant without losing surprise and that thing can smell anyone but Alice. splitting up is scooby do-tier nonsense. and kiting an enemy with a ballista doesnt feels o good. weve set up the trap now we wait. i really wonder how much dmg we really will do but i wouldnt believe it when i heard whats possible. its a huge gambe though but its the best we have.
