While I enjoyed the adventure, where are a few areas where it could be enhanced...

1) Map: There needs to be a map showing the city's location in the Anauroch Desert relative to at least the first of all 4 tombs and any other landmarks. 2) Magic/Treasure value: xp/2 = gp is a good rule of thumb for awarding Magic/Treasure value as anything more starts unbalancing the game upon reaching Tier 2 and above 3) Scaling: The adventure is stated as 1-4th level, but there is no scaling... maybe something on the Heroic (Deadly) scale would be nice. 4) Map: A map of the City would be nice as it's a home base for the remainder of the trilogy, I think. 5) Desert related Magic Items: Alchemy Jug, Decanter of Endless Water, Orb of Direction, etc...

I'm a Power Player running a solo 4th level Yuan-ti Sorlock Bounty Huntress fresh off of a Coastal adventure whose epic heroics caught the attention of the ruler of a lost city that has mysteriously reappeared... what was needed was secrecy and who better than a complete outsider?

Mold Earth was such a handy Cantrip for this adventure, making the sand storms a non-issue.

The Blind Fighting Feat along with an Eversmoking Bottle reversed the Action Economy of every encounter so that the Flanking Maneuver Advantage was eliminated while giving my character Advantage due to their Blindness.

I'm really looking forward to the next installment!!!
