Ah too bad, Sleep would have been useful!
I'd still throw a firebomb in there for confusion. And Alice has ball bearings. We should use them after the caltrops!
I'm not convinced we can do much damage ranged. Two arrows one of which is poisoned and Yuya's toll the dead. We won't drop any of them this way.

[Ashley] I say throw the spikes and back up ready to range while Nixie pounces 

damn youre right
no idea where i read that up honestly i was surprised Yulya was supposed to have this but it seemed fitting and we missed so many things that it wasnt out of question. so much for the brilliant plan.

ok still the question is whether to barricade the door or not. having them come out of the lower door while we ambush the upper is not good.

heres what we will do.
-Cat spreads out caltrops in a line outside the door but  in some distance
- Cat opens the door
- Alice throws a firebomb in
- Cat closes the door
- Alice and Cat move away from the door.
- Yulya casts BLESS
- Yulya casts Emboldening Bond between Alice and Cat
-Yulya casts SLEEP at the door
- Ashley summons us some cats to deal with the enemy
-Bugbears storm out and into Sleep effect falling down on caltrops. Alice can incapacitate first one with the net and disarm others that fall unconscious by batting away weapons with her pole.

alternative:
we barriccate the door with two tables. then set up an ambush at the 2nd door i assume they are connected

we gotta clarify how sleep spell works theres a lot of discrepancy between 5e and 2024 edition.
now it only has 5 ft radius and 1 min duration. question is if it works on anyone who runs into the sphere for that minute. depending on Joys interpretation we will decide if sleep is effective or not.

onions?

Not in UK, no, but something
