I have created these Random Encounters Tables with monsters from the general books of DnD 3.5 edition, from books of the Forgotten Realms setting, Ghostwalk, Heroes of Horror and some from the Dragon Magazines. My first priority for each monster was their environment and their organizations as it was descriped in their entries.

Notes

• The maximum number of monsters per encounter is 20.
• You may disagree with some of the total CRs, especially those who have 5, 7, 11, 15 or 20 monsters.  Please be careful with them. My players are always buffed up, so they are ok by me.
• The marsh environment includes bogs, marshes and swamps.
