Encounters for wilderness, urban and dungeon, random generation of dungeons, wilderness terrain, merchants and other scenarios for solo D&D. D&D Solo Adventure: Tables Of Doom has random tables to generate monsters, traps, clues, loot and other elements for solo adventures.

For characters you can add personality traits according to your character stats with Ability Traits, find some Trinkets with Loot the Room or work out magic items for PCs and NPCs with character magic item tables (one of mine)
