Lost Mines of Phandelver— supplements, encounter tables, and DM tools I've found useful
Lost Mine of Phandelver is the most common starting module for new DMs, and Phandelver and Below extends the story significantly. The problem is that resources for both modules are scattered across a dozen different sites, with wildly varying quality.
I put together a single reference page for both campaigns, covering:
- Third-party supplements on DMsGuild that add encounter content, expanded location maps, and additional NPC development
- Map resources (player-facing and DM-reference)
- Tools that help with the hex-crawl sections in Phandelver and Below specifically
- Prep guides for the tonal shift between LMoP (classic fantasy) and PBTSO (cosmic horror)
The tonal shift section took me longest to research. PBTSO assumes players already have LMoP attachment to the region, and several of the supplements help bridge that transition in ways the book doesn't fully address.
If you are interested in the resource list it is in the comments.
