Hexploration

Exploration within a roleplaying campaign can be done in many ways. This page explains the home brew rules for exploring, mostly taken from the Alexandrian and mixed with Pathfinder 2 Exploration and Hexploration.

Player choices

These are the player-focused part of the rules. Most exploration activities ("actions" during exploration) are performed during a full Watch, though there are exceptions. If there is an Encounter, the Exploration Mode is halted until the Enconter is resolved and will resume at an appropriate point after.

Hexploration Time

Activities can vary slightly depending on the type of Watch (4-hour chunk of the day) it is performed on:

• Active - Group is stationary, repairing equipment, foraging, exploring a local surroundings carefully, etc.
• Rest - Group is at a camp or staing in a house, resting. Some minor activities are sometimes done.
• Travel - Active travel in a direction or towards a goal. A speed is also chosen:
  • Normal (100%) - Normal travel gains normal speed but no stealth checks.
  • Slow (66%) - Careful travel gains bonus to navigation, ablity to make stealth checks, lowers encounter chance by 50%.
  • Exploration (50%) - Trying out side trails gain navigation bonus, +100% chance of encounters but no stealth checks.
  • Fast (150%)- Quickly move gains faster speed but no stealth checks, penalty on Wisdom (Perception) and navigation.

Player Activities

Each character can perform one activity per watch (unless it says they can be combined):

• Foraging (Active Watch or Slow Travel Watch) - Survival vs Forage DC of the terrain.
  • Crit success = 4 rations and a source of water
  • Success = 1 ration or a source of water.
  • Fail = Neither found
  • Crit fail = You attract trouble, eat something you shouldn't, or otherwise worsen your situation. You take a –2 circumstance penalty to checks to Subsist for 1 week.
  • Grazing (Actie Watch) - If an appropriate biom (determined by the GM), man animals (like horses) can graze and be fully fed b grazing for 1 watch
• Navigating (Active Watch or Travel Watch) - Make navigation checks. A second character can navigate to add its proficiency to the check. If no character does navigating, the direction is determined randomly.
• Pack-pulling (Travel Watch) - Lead a number of animals equal to twice their Nature modifier. (This number includes the pack-puller’s mount, if any.)
• Resting (2+ Rest Watches) - Needs to be taken consecutively to gain the benefits of a rest (see limits). More watches may be needed.
  • If a character does not spend at least one full watch per day resting; succeed at a Fortitude check (DC 16 - the number of hours they slept, if any) or suffer a level of Fatigue.
• Scouting (Active Watch or Travel Watch) - Choose Reporting or Pathfinding
  • Reporting - If the navigator gets a scout report they can roll their Navigation check twice and choose which die to use.
  • Pathfinding - Survival check on area's Navigation DC.
    • Crit success = Treat trackless terrain as if it had a trail for two watches and may provide a scout report to the navigator.
    • Success = Treat trackless terrain as if it had a trail for one watch.
    • Fail = No effect.
    • Crit fail = You attract trouble, eat something you shouldn't, or otherwise worsen your situation. You take a –2 circumstance penalty to checks to scout for 1 week.
  • Scouting can only happen if character has a faster speed than the rest of the expedition (or expedition is stationary).
  • An additional encounter check is made for each scouting group
• Sentinel (Active Watch or Travel Watch) - Actively makes Perception checks to detect threats or notice anything else out of the ordinary.
  • Outrider - Sentinel may ride ot to detect/prevent threats.
    • If an encounter is generated for the expedition, Sentinel can do Perception check vs DC 15 (or stealth) to detect it before the expedition encounters it.
    • An additional encounter check is made for each scouting group, but has one-half the chance of an encounter.
• Sighting (Active Watch) - Find an outlook to see further into the wilderness for threats.

TRACK DCs
SURFACE	DC
Very soft ground (snow, wet mud)	5
Soft ground (sand)	10
Firm ground (fields, woods, thick rugs, dusty floors)	15
Hard ground (bare rock, indoor floor, streambeds)	20
CONDITION	MODIFIER
Multiple people	-2
Large group	-4
Very large group	-8
Creature is bleeding	-4
Every day since the trail was made	+1 per day
Every hour of rain since the trail was made	+1 per hour
Fresh snow cover since the trail was made	+10

• Tracking (Active Watch or Travel Watch*) - Choose Finding Tracks (Active Watch) or Following Tracks (Travel Watch)
  • Finding Tracks: Searching a significant wilderness area for tracks. The tracker makes a Perception check against the appropriate Track DC.
  • Following Tracks: Once tracks have been found, a tracker can follow the trail during a travel watch by making a Survival check against the appropriate Track DC. A new check must be made each time the trail enter a new hex.
    • If a trail is lost, it may be possible to reacquire it using the Finding Tracks action.
• Cover tracks (Slow Travel Watch) - Attempt to cover the expedition's tracks. Stealth or Survival check creates the Track DC for any pursuer attempting to find or follow their tracks.
  • +5 on hard ground and -5 on soft
• Trailblazing (Travel Watch) - Slows the chosen speed by an additional 50%. Allows the expedition to lay down a visible or hidden trail. See rles here and here
• Downtime Activities - These activities normally take at least 4 consecutive Active Watches to perform ("a day or more") and may not be applicable.
  • Subsist (4 Active Watches) - Sustenance and shelter, see rules

Full rules

Watches

A watch is the basic unit for tracking time. A watch is equal to 4 hours.

Determine Time Within a Watch: To randomly generate a particular time within a watch, use 1d8 to determine the half hour and 1d30 to determine the exact minute (if necessary).

There are six watches per day and three types of watch:

• Active
• Rest
• Travel

While traveling, it is generally assumed that an expedition is spending two watches per day traveling, two watches per day resting, and two watches per day engaged in other activities.

Forced March: If a character spends more than two watches traveling in one day, they must make a Constitution check (DC 10 + 1 per hour of additional travel). On a failure, they suffer one level of exhaustion/fatigue.

Travel Pace

During each watch, the expedition determines their travel pace.

Normal: (x1) An expedition traveling at normal pace cannot use Stealth checks to avoid detection.

Slow: (x2/3) While moving at a slow pace, the expedition is purposely being careful. An expedition traveling at slow pace:

• Gains advantage on navigation checks.
• Can make Stealth checks to avoid detection.
• The chance for a non-exploratory encounter is halved. (If a non-exploratory encounter is generated, there is a 50% chance it doesn’t actually happen.)

Exploration: (x1/2) While exploring, an expedition is assumed to be trying out side trails, examining objects of interest, and so forth. While exploring, an expedition:

• Cannot use Stealth checks to avoid detection.
• Gains advantage (PF2 = +5 circumstance bonus) on navigation checks.
• The chance for encounters is doubled.

Fast: (x1.5) While moving quickly through the wilderness, expeditions traveling at fast pace:

• Cannot use Stealth checks to avoid detection.
• Suffer disadvantage to Wisdom (Perception) checks.
• Suffer a -5 penalty to navigation checks.

The most common speed is 30ft, 3mph, 12 miles per watch, 24 miles per day.

Speed	Feet per Minute	Miles per Hour	Miles per Day
10	100	1	8
15	150	1-1/2	12
20	200	2	16
25	250	2-1/2	20
30	300	3	24
35	350	3-1/2	28
40	400	4	32
50	500	5	40
60	600	6	48

Terrain

The type of terrain modifies the speed at which an expedition can travel.

• Highway: A highway is a straight, major, paved road.
• Road: A road is a dirt track or similar causeway.
• Trail: An irregular byway. Probably unsuitable for most vehicles and may only allow for single-file travel. Most off-road travel follows local trails. A known trail does not require navigation checks, although a known trail in poor repair requires a DC 10 navigation check to follow.
• Trackless: Trackless terrain is a wild area with no paths. +2 to navigation DCs.

TERRAIN	HIGHWAY	ROAD/TRAIL	TRACKLESS	NAVIGATION DC	FORAGE DC
Desert	x1	x1/2	x1/2	12	20
Forest (sparse)	x1	x1	x1/2	14	14
Forest (medium)	x1	x1	x1/2	16	14
Forest (dense)	x1	x1	x1/2	18	14
Hills	x1	x3/4	x1/2	14	12
Jungle	x1	x3/4	x1/4	16	14
Moor	x1	x1	x3/4	14	16
Mountains	x3/4	x3/4	x1/2	16	18
Plains	x1	x1	x3/4	12	12
Swamp	x1	x3/4	x1/2	15	16
Tundra, frozen	x1	x3/4	x3/4	12	18

Note! These DCs are for e and ma have to be revised for PF2

Conditions

CONDITIONS	SPEED MODIFIER
Cold or hot climate	x3/4
Giant terrain	x3/4
Hurricane	x1/10
Leading mount	x3/4
Poor visibility (fog, darkness)	x1/2
River crossing	x3/4
Snow cover	x1/2
Snow cover, heavy	x1/4
Storm	x3/4
Storm, powerful	x1/2

Leading Pack Animal: Under normal circumstances, a pack-puller can lead a file with a number of animals equal to their passive Wisdom (Animal Handling) skill.

Poor Visibility: This condition also gives disadvantage to navigation and forage checks.

River Crossing: This penalty applies to any watch during which a river must be crossed. This does not apply if the characters are following a road which has a bridge on it, but does apply if they’re traveling cross-country and must seek out a bridge.

Hexes

1 Hex = 12 miles (center to center / side to side) = 7 mile sides = 124 square miles

Movement on the wilderness hex grid is abstracted. In order to determine if an expedition has left a hex, you must keep track of their progress within the hex.

Starting in a Hex: If an expedition starts movement within a hex, it requires 6 miles of progress to exit any face of the hex.

Optional Rule: You can choose to bias a starting position. For example, you might see that a river flows near the western edge of a hex. If the PCs start traveling from that river, you might decide it only takes 2 miles to exit through the hex’s western face and 10 miles to exit through its eastern face.

Crossing Hex to a Far Side: It requires 12 miles of progress to exit a hex through one of the three faces on the opposite side.

Crossing Hex to a Near Side: It requires 6 miles of progress to exit a hex through one of the two nearest faces.

Changing Direction: Changing direction more than once within a hex will result in the loss of 2 miles of progress each time direction is changed.

Back the Way We Came: If characters deliberately double back along their own trail, simply reduce their progress until they exit the hex. If they leave back through the face through which they entered the hex for any other reason (by getting lost, for example) it requires an additional 1d6-1 miles of progress to exit the hex (unless circumstances suggest some other figure).

Food and water

Food: Small and medium creatures require 1 ration of food per day, small require 1/2. They can go without food for a number of days equal to 3 + their Constitution modifier (minimum 1) before suffering 1 exhaustion level per day thereafter. A normal day of eating resets the count of days without food to zero.

A creature on half rations counts as going a ½ day without food (and these half days accumulate until they can eat full rations).

Water: Small or medium creatures require 1 gallon of water per day, or twice that in hot weather. A creature on a half ration of water must succeed on a DC 15 Constitution check at the end of each day or suffer a level of exhaustion. If they drink less water than that, they suffer a level of exhaustion automatically. If the character already has one or more levels of exhaustion, the character takes two levels in either case.

Waterskins hold a half-ration of water.

Army movements

Large scale movement is hindered by several factors, well summarised here.

Rule of thumb 8-12 miles per day rather than 24 odd. Can probabl be refined with eqation + dice.

Resting

• RAW

Homebrew:

Same as SAW, but marching or other streneous activity in excess of 1h between rest periods will reset the time counted as rest. Taking turns on guard dut generally does not affect rest.
