Phandelver and Below Review — A Familiar Beginning Needs a Careful Turn Toward Horror

Phandelver and Below: The Shattered Obelisk combines a revised Lost Mine of Phandelver with a much stranger continuation. The early frontier adventure is familiar and approachable; the later chapters move underground toward psionic corruption and Far Realm horror. The problem is not a lack of material. It is making those two kinds of campaign feel like one story.
The original adventure is inside the book
The opening returns to the goblin ambush, Phandalin, the Redbrands, regional investigations, Cragmaw Castle, and Wave Echo Cave. Buyers do not need a separate copy of Lost Mine to run the beginning. Its town-and-region structure still gives new characters understandable goals and a useful home base.
That also means a returning group will recognize considerable material. Someone who already completed Lost Mine should examine where the continuation begins and adapt references to the earlier party’s actual decisions. This is an expansion with a revised beginning, rather than an entirely new adventure from its first page.
The familiar portion’s strength is clarity. Finding missing people and uncovering local threats creates momentum without demanding an extensive setting briefing.
The obelisk changes what the town is facing
Later chapters develop disappearances, unusual goblins, obelisk fragments, and a threat associated with mind flayers. Phandalin’s transformation and the influence of the Far Realm become central concerns. The characters are no longer simply resolving the region’s ordinary dangers.
That escalation has a useful emotional possibility: protect the same community at a much higher level of danger. It is more compelling than discovering that the entire first adventure was only a tutorial with no lasting importance.
The transition is still the book’s weakest structural point. A local mine plot and a cosmic corruption plot do not automatically connect because they share a town. Earlier clues need emphasis, and familiar residents need to remain present as people rather than a collection of symptoms.
The underground locations give the continuation identity
The expanded material includes an ancient site at Talhundereth, the Crypt of the Talhund, Gibbet Crossing, and deeper destinations such as Illithinoch. The adventure eventually reaches territory where ordinary underground exploration becomes alien rather than merely dark.
These locations give the later campaign a different texture from the first half’s hideouts and frontier ruins. Psionic creatures, altered environments, and the obelisk’s influence provide material for groups wanting a more unsettling D&D adventure.
The tradeoff is tonal. A group attracted to a friendly beginner adventure may not want bodily transformation and reality-threatening horror afterward. The book should be introduced as a campaign that changes in this direction, with boundaries discussed before the change arrives.
Familiar NPCs are the connective tissue
The town material gives the DM people whose lives can matter across both portions. That continuity is more valuable than simply retaining the name Phandalin. If characters remember who helped them, who doubted them, and whose livelihood improved after earlier victories, later changes have weight.
I would make those connections the priority when preparing the transition. That is a specific repair to the book’s structure: keep the community visible while new villains and locations expand the scale.
A group that runs the original material briskly and then immediately descends into the next dungeon may experience the campaign as two adventures bound together. There is nothing inherently wrong with that, but it is less satisfying than the title’s promise of uncovering a deeper threat beneath a familiar place.
How much extra value does it offer?
For a new group wanting a campaign that starts simply and continues well beyond the original Lost Mine, the amount of adventure is appealing. Additional creatures and strange locations also give an experienced DM pieces to reuse elsewhere.
For a group that already owns and has run Lost Mine, the decision rests chiefly on the continuation. Buying another version of the beginning is less persuasive than wanting this particular underground horror campaign.
B3’s verdict
The Shattered Obelisk offers a solid familiar opening and a substantial, distinctive second act. It asks more of the DM in connecting them than its all-in-one presentation might suggest. Buy it if protecting Phandalin while the threat grows increasingly alien appeals to the whole group. Its value is strongest for a fresh campaign or for returning players who want that change of tone. The continuation needs deliberate foreshadowing and recurring town relationships to feel earned.
