DnD 5e Extreme Terrain Random Encounter Tables - 57 d100 Tables, 1140 Rated Encounters, 15 Biomes

Fifteen kinds of country that does not want you there, and on every spread all twenty-eight lines were written for that one ground.

That is the difference. Most of the work in an encounter table is not the monster - it is the sentence that tells you what it was doing before you arrived, what gave it away, and what it costs you to deal with it there. Those lines are usually shared across a whole book. Here they are not. A glacier is empty and a mangrove is not, and a line that reads well on one reads like filler on the other.

WHAT YOU GET

57 d100 tables across 15 places - Orchard and Vineyard, The Hunting Grounds, Savanna, The Steppe, Peat Bog and Fen, Mangrove and Delta, Sea Cliffs and Stacks, Canyons and Gorges, Caves and Caverns, The Petrified Forest, Hot Springs and Geysers, The Salt Flats, Above the Treeline, Tundra and Taiga and Glacier and Icefield.

1140 encounters in total, drawing on 254 different creatures.

420 lines of flavour, 28 for every place: 12 for what they were doing, 8 for what the party notices first, 8 for what makes it awkward. None of them is repeated anywhere else in the book.

THE LAST COLUMN IS THE POINT

Every row says how it lands for four characters in the middle of that tier: easy, fair, hard or deadly. Those are not estimates. Each was computed from the creature and the number rolled.

And no roll on any table in this book can produce a fight a competent party cannot walk away from - not even the highest roll of the biggest die. That was checked on all 1140 rows at their worst possible result.

Nasty things stay rare, the way they should be, so when one lands it is frightening rather than routine.

FOUR ROLLS MAKE A SCENE

Roll d100 for who is there and how many. Roll d12 for what they were doing before you arrived. Then roll d8 twice: once for what the party notices first, once for what makes this awkward. All four sit on the spread for that place, so nothing is looked up in two places.

THE TIERS

12 of the 15 carry all four tiers of play: levels 1-4, 5-10, 11-16 and 17-20.

Savanna, Peat Bog and Fen, and The Salt Flats carry three rather than four. A seventeenth-level party does not go looking for random encounters on open grass or a salt pan, and a table for a place nobody at that level goes is padding.

WHERE THE CREATURES CAME FROM

Every placement can say why it is there. Nothing appears in ground it could not physically be in - no bird in the lake and no shark in the sky - and that was checked against the stat block rather than by eye.
