I just ran the coffin maker's shop fight in Reloaded and it was a lot of fun for myself and my players. I have a strong party of a paladin, a druid, a bladesinger wizard, an Aasimar sorc/bard, and a cleric so I have been using a moderate amount of tactics in fights. One thing that added a lot of interaction and fun for me was having the vampire spawn pull their grapple targets up the wall of the shop.
This fight took place outside the shop after the trap was triggered, the bones were looted by an invisible player, and after Van Der Voort jumped(nat 20) out of the second story window trying to escape the vampire spawn.
In the third round, after separating the cleric (just because of positioning and luck) from the party on the ground, the spawn started pulling players they had grappled up the walls at half move speed. This threatens falling damage and lets them separate players in a way that is not countered by simple movement. At the end of the fight, Volenta was also climbing the walls to get out of range of father Lucien's spirit guardians spell as she tried to finish off the bladesinger she had crit on.
Because of this my players: Scrabbled up the wall as a wild-shaped tiger to de-shift and slap a cure wounds on the 2 failed death saving throw cleric; misty stepped out of a grapple while being dangled off the roof; thorn whipped Volenta off the wall and into Lucien's spirit guardians.
Dice luck was definitely on my side, the Aasimar only had one roll go his way all night, but liberal self healing and a sanctuary from father Lucien prevented any player deaths.
