Weather and Terrain

An expansion of Tread and my hexcrawl rules, laying out the mechanical effects of terrain and weather.

To briefly review the basics:

• 24 hour days, with 16 hours of daylight and 8 hours of night.

• Hexes are 6 miles wide and take 4 hours to traverse.

• Tread is marked on a hex's border every time the party crosses it, up to 3 times.

• Each Tread marked on a border reduces the time to cross by 1 hour.

• During exploration, each traveler in the party may Scout (get there safely), Navigate (get there quickly), or Forage (get there efficiently). The more travelers on a task, the more dice rolled for that result.

Terrain

Some types of terrain uses these terms:

• Degrade: Remove -1 Tread from all borders

• Min X: begins with X Tread on all borders, and Tread can never be less than X on any border

• Max X: Tread on all borders can't exceed X

• Forest: No effect

• Prairie: Min 1

• Settlement: Min 2

• Swamp: Max 2

• Mountain: Max 1

• River/Riverbed/Railway: 1 Tread along route

• Canyon/Fissure/Lake: Max 2, completely impassable without specialized tools

• Windy Desert: Degrade every 10 nights

• Snow-Covered Mountain: Max 1, Degrade every 10 nights

• Living City: Min 1, Degrade every other night 

• Labrynth: Degrade every night unless any connected Labrynth is occupied by a traveler

Weather

Weather is rolled once per day. I'll be use a hex flower in the actual campaign to keep things feeling grounded.

In addition to any other effects,  all weather offers a situational +1d on relevant rolls.

• Rain/Snow: no additional effect

• Sunny: no additional effect

• Breezy/Windy: no additional effect

• Heavy Wind/Rain/Snow: mark no new Tread

• Sandstorm: -1d Navigating

• Heavy Fog: -1d Scouting

• Hail/Drought: 1/Day, spend a relevant item or take Scuffed/Sunburned as a Tier 1 Harm (you can also spend items to protect other travelers)

I think that coveres the main weather/terrain the players are likely to encounter, but do lmk in the comments if I missed any obvious ones 😅. I'm hoping to do a playtest sometime soon, I'll post the results once that happens.
