Adjective Website


  • Marsh- Marshes are defined as wetlands frequently or continually inundated with water, characterized by emergent soft-stemmed vegetation adapted to saturated soil conditions.

  • Swamp- any wetland dominated by woody plants.  Can be either forested swamp (trees) or shrub swamp. 

  • Bog- characterized by spongy peat deposits, acidic waters and a floor covered by a thick carpet of sphagnum moss. Bogs receive all or most of their water from precipitation rather than from runoff, groundwater or streams. Lack nutrients for plant growth,

  • Fen- similar to bog, but more nutrients and plant growth.


  • Evergreen- retain foliage all year.  Dense & multi layered.  Typically heavy rain areas, near the equator.

  • Deciduous Forests- drop leaves, change color.  Oak, beech, walnut, maple, chestnut, hickory.

  • Coniferous Forests- needles & pines.  Spruces, hemlocks, pines, firs.  

  • Tropical- near equator.  Lots of rain.  Hot.   Broadleaf trees, mosses, ferns, palms, and orchids all thrive in rain forests. The trees grow very densely together, blocking light.  Animals: monkeys, snakes, frogs, lizards, and small mammals

  • Temperate- usually deciduous trees, some conifer.  Can grow very lare trees.  Common animals roaming the woods are deer, elk, bears, owls, and marmots.

  • Boreal- evergreen like pine, fir, and spruce trees, live here. Animals: moose, bears, lynx, wolf, deer, wolverines, caribou, bats, small mammals, and birds.


You can further modify the DC to track based on the circumstances


  1. Determine location.  Cover?  Visibility?  

  2. Do players build fire?  

Sleeping in Armor

Sleeping in light armor has no adverse effect on the wearer, but sleeping in medium or heavy armor makes it difficult to recover fully during a long rest.

When you finish a long rest during which you slept in medium or heavy armor, you regain only one quarter of your spent Hit Dice (minimum of one die). If you have any levels of exhaustion, the rest doesn’t reduce your exhaustion level.

Finding Shelter:

1-8  Unable to find suitable shelter.  You are in the open, possibly difficult terrain.

9-13  You find a clearing, but nothing with cover Stealth Disadvantage

14-17  You are able to find partial cover.  Ruins, overcropping, etc.  Or you are able to find materials to put together a makeshift tent camfolaged.

18-20: you find a cave, an abandoned hovel.  Stealth Advantage.


Magical Travel Speed

If players have mounts/flying/etc:

  • In 1 minute, you can move a number of feet equal to your speed times 10.

  • In 1 hour, you can move a number of miles equal to your speed divided by 10.

  • For daily travel, multiply your hourly rate of travel by the number of hours traveled (typically 8 hours).

  • For a fast pace, increase the rate of travel by one-third.

  • For a slow pace, multiply the rate by two-thirds.
