Sean, I had a couple questions about how you ran the final encounter of Tomb of Annihilation.
When the party encountered the atropal, did you follow the book’s suggestion to have Acererak show up only after it was dead, or did you have him appear after one or two rounds? Also, did you use the atropal’s summon wraith ability at all? I mainly ask because I’m running my group through the Adventurers League content for the ToA season, but I want to take them through at least part of the Tomb of the Nine Gods as a big climax to the entire campaign. They’ll be level 20 by that time, so I want to make sure I beef up the encounter accordingly. My thought was to definitely have Acererak appear pretty much as soon as they start to attack the atropal and to have the atropal be able to summon three wraiths at a time (still recharging the ability on a 6). That said, I don’t even know if that will be enough to not get steamrolled by a 20th-level party, so I’d appreciate any feedback.
