5E DnD Horror Encounter Tables for Halloween

Among the bones of fallen warriors and rusted weapons you see a dark figures stood around a prominent tombstone. What appears to be a wreath of flowers is stained by and putrid black liquid being poured from a flask...

From a roll of 14 on "Sites of the Dead" table below

D&D Horror Encounters

D&D is it's own brand of fantasy, and but horror elements can be seen in Ravenloft and many creatures taken from myth and folklore.

The encounter tables here focus on lower levels (1-4) as this is where it's easiest to bring in elements of mystery and fear.

Haunted House - this might be a mansions, ruined temple or abandoned fortresses.

Sites of the Dead - Graveyards, battlefields, tombs, catacombs, memorial gardens.

Dark Cults - The cults can be combined with other tables such as base in a mansion or the woods.

Gloomy Woods - Places of eternal twilight, wolf howls, malevolent fey and dangerous strangers.

Lonely Road - Along this road lies ruined inns, unfriendly villages, families of nomadic travelers and refugees from disaster.

A pdf of these tables and more is at the DM's Guild as Spooky Encounter Tables, including mid-level (5-10) tables and others expanding each of the 5 themes here.
