here is a rough idea of what happened. the numbers rolled may be off. feel free to edit for accuracy or anything i missed. copy past from a reddit post i made so i avoided names and what not. again feel free to edit.
the halfling boy shows the party the back entrance to the Redbrands hideout (rm8).
They ignore bargaining attempts from the Nothic instead deal nearly 70 damage before nothic’s first turn. dropping 20s like the are hot potatoes our goliath fighter is cutting him down. im just making up saves. i literally said “give me a dex save to recover from tripping on some bones” … 18.
they told Sister Garaele they would deliver the comb to the banshee today. she warned if they cheated her Tymora would be angry. Tymora can see they are not going to the banshee. whoever is holding the comb gets disadvantage on all rolls. Wizard sends pigeon out to place the comb stuck in a spot high on a pillar 20 feet up where the pigeon could retrieve it at a later time. the pillar has disadvantage.
There are 4 options here and they go to room 7. Perception 21 to spot the secret door leading down to Iarno “Glasstaff” Albrek‘s room. Part of the party moves around to what looks like the other side of the room. Using the lightfoot wizards pigeon they can simultaneously barge in from either side. 1… 2… 3… some of the party is in the work shop (room 11), the rest get SURPRISE on Iarno “Glasstaff” Albrek (room 12).
Spotting the glass staff leaning on the desk the Human Rogue does acrobatics check 27 to parkour in and out snagging the glass staff. with the Mobile feat and cunning action to dash (even after forcing "difficult terrain " through allies) he ends his turn back in room 7. wanting to interrogate Iarno “Glasstaff” Albrek the dwarf fighter goes in for a grapple. Iarno “Glasstaff” Albrek nat 20 that strength check. as a reward i allow Iarno “Glasstaff” Albrek to react with shocking grasp for 9 dmg.
meanwhile the other part of the party (goliath fighter and lightfoot warlock) run full speed through the workshop to break down the door to Iarno “Glasstaff” Albrek’s room. they want to attempt to grapple whomever they see once they get through
Back in the bedroom the lightfoot wizard attempts a charm. This wizard is studying divination and his portent ability allows him to replace a roll with a value rolled at the beginning of the day. So Iarno “Glasstaff” Albrek WIS save is roll of 1. He now treats these adventures as friendly acquaintances for an hour. their plan is to interrogate in then murder him within the hour.
Simultaneously the goliath got a 24 check to break down the door and not knowing what is going on he jumps for the grapple. No joke Iarno “Glasstaff” Albrek nat 20 strength contest again. He wont be dropped. halfling wizard charmer talks everybody down and they start to chat with Iarno “Glasstaff” Albrek.
Conversation moves to the workshop (rm11) and the pirate stealth check 19 to slip back up the stairs to inform the rogue about the charm and where everybody is headed.
on the way out Iarno “Glasstaff” Albrek reaches for a missing staff and starts to get confused. pocket check: wallet, keys, phone, no staff. the party is doing such a great job role playing and keeping him busy he hasn’t really asked if anybody has seen where he placed his staff yet. He doesnt really know how many people are involved here.
Idea! Iarno “Glasstaff” Albrek rat familiar can go wander around and see the glass staff in the rogues hand in room 7. until the human pirate nat 20 hand axe to the rats face. This has caused the wizard to be concerned and he remembers that he is looking for his staff. he hastily exits the workshop.
