Suggested rework of Maps and Wilderness Navigation

Maps help avoid becoming Lost.

Map Creation:

Map creation requires Cartographer's Tools and either of:

Modifiers:

Spells or effects with a duration of 1 hour or greater can be applied (eg a Divination wizard's Portent, but not Guidance).

The roll can be made with Advantage under these circumstances:

Making the Map Making test with advantage takes three times as long as normal.

The map you create has a Map Bonus equal to your Proficiency Bonus at the start of the session in which you conduct the reconnaissance to make the map. All extant maps at the time of introduction of this mapping system are reset to a bonus of +2 (the Proficiency Bonus).

You can map a number of tiles equal to the outcome of your Map Making roll. Each tile covers a 1 square kilometre area.

You cannot split tiles to map an area 1/2 a tile wide to double the length of your map. Tiles are mapped in their entirety.

To map remote map tiles you have not traversed (in person or via proxy), make a Perception test. The DC is equal to 10 + the distance in kilometres to that tile. A Spyglass grants Advantage on this test.

The Map Making test consumes:

An Outpost occupies one tile (regardless of its real size). The 30 tiles around any Outpost (3km radius) are automatically mapped (at a +2 Map Bonus; the Proficiency Bonus) by professional NPCs in the process of constructing the Outpost and its Watch Tower. Every Outpost has a Watch Tower to enable rapid, long-range communications since magic may not always be relied upon. A sentinel in the Watch Tower scans the nearby terrain and other Watch Towers within line-of-sight for changes (eg fire, flood, travellers, monsters, signals). A Watch Tower is equipped with a Spyglass.


Wilderness Navigation:

When you travel along roads, you do not need to make a Wilderness Navigation test.

When you travel along tiles which have been mapped on one or maps you carry, you make your Wilderness Navigation test with a Map Bonus equal to the minimum Map Bonus of any map you use.

When you travel along unmapped tiles which are adjacent to mapped tiles, those tiles are effectively mapped at half that map's Map Bonus (round down).

You make a Wilderness Navigation test to move to a specific Destination, or to follow a Bearing. A Bearing is not a Destination. Following a Bearing requires Navigator's Tools.

To make a Wilderness Navigation test, roll 1d20, add the minimum Map Bonus which applies, then:

The roll can be made with Advantage under these circumstances:

If you travel exclusively along mapped tiles:

If you travel along unmapped tiles adjacent to mapped tiles or you follow a Bearing:

If you travel along unmapped tiles:


Lost:

When you are Lost:


Worked Examples:

A party sails 3km North up Arkett River into Akeula Lake then 10km North East to the Blue Pride then investigates its surrounds thoroughly before returning home.

The following week, a party conducts a follow-up expedition using the maps created by the pioneers to try to reach the orange glow.

They arrive at the Blue Pride later than expected, but successful. They look to the East.

At this point they spot another shipwreck in the marsh, 4km away in a tangential direction. They head toward it without a map. Their Wilderness Navigation check is made with no Map Bonus against a DC of 18 (15 base +3 unmapped tiles (the first tile they traverse has a Map Bonus of +1 because it is adjacent to a mapped tile, so it does not raise the DC). The shipwreck contains sea charts made by a level 15 character, so they grant a +5 Map Bonus within the mapped area... which is nowhere near here.
