Cartography

A folio of the realm

Cartography

Cartography is the Treasure Hunter's gateway skill. It crafts maps of the surrounding land, decodes the Treasure Maps that drop from monsters, and — since Publish 105 — controls the dig-radius accuracy when retrieving treasure chests in the field. Mining no longer plays any role in Treasure Hunting; Cartography handles both decoding and digging.

Mechanics

To craft a map, equip a Mapmaker's Pen (Tinker-craftable; sold by NPC Mapmaker vendors). Use the pen on a blank map (sold by Mapmakers) or a Blank Scroll. The skill check rolls; on success, the local terrain is captured to the map.

A character may only draw maps in the Trammel and Felucca facets. Attempting to draw a map in Ilshenar, Malas, Tokuno, Ter Mur, or the Stygian Abyss produces an Indecipherable Map — a sentinel result that signals the wrong-facet attempt.

Treasure Map decoding

When a Treasure Map drops from a monster (titled "tattered map of "), it must be decoded before the digging location is revealed. Double-click the tattered map; the Cartography skill check rolls. On success, the "tattered" prefix is removed and the map shows the dig area.

Once decoded, any character can read the map — Cartography is required only for the initial decode. This is the critical multi-character workflow: a high-Cartography decoder reveals the location, then any character (including a non-Cartography Treasure Hunter) can carry the decoded map to the dig site.

Dig accuracy — Publish 105 change

Pub 105 (June 2019) restructured Treasure Hunting. Cartography replaced Mining as the dig-bonus skill, controlling the radius around the chest's exact tile within which the player can stand and dig successfully:

Cartography skill Dig radius
0 – 50.9 1 tile (must pick the precise location)
51 – 80.9 2 tile radius
81 – 99.9 3 tile radius
100 (GM) 4 tile radius

A 50 Cartography character must stand on the exact dig tile to retrieve the chest — no adjacent-tile error margin. A GM Cartographer has a 4-tile radius, dramatically reducing the trial-and-error of finding the precise location. For high-level T-Map runs (level 5-7), GM Cartography is conventional because the dig zone overlaps multiple terrain features.

The chest's actual location and contents are unaffected by Cartography skill — only the dig-tile-tolerance is. A treasure chest itself is opened by Lockpicking (and Remove Trap on level 4+).

Crafted maps

A trained Cartographer produces several map products via the standard craft menu:

Map Skill range Notes
Local Map 30 – 50 Small-area map of immediate surroundings.
City Map 50 – 65 Town-wide layout.
Sea Chart 60 – 70 Maritime navigation. Useful with the Fishing skill for net deployment.
World Map 70 – 99.5 Full Trammel/Felucca world.
Eodonian Wall Map 100, recipe-gated Decorative; recipe is a reward from the Exterminating the Infestations quest in Valley of Eodon.

The Eodonian wall map cannot be crafted without first reading the recipe — a quest gate, not a skill gate.

Training

A Mapmaker NPC near a bank is the conventional training base. Buy blank maps and pens, draw, sell completed maps back to the NPC for a small profit. With Felucca pricing (cheaper than Trammel), the gold cycle covers itself with luck.

Skill range Method
0 – ~30 Buy from any city's Mapmaker NPC.
30 – 50 Local Maps.
50 – 65 City Maps.
60 – 70 Sea Charts.
70 – 99.5 World Maps.
99.5 – 100 Level 3 and 4 Treasure Maps (use the GGS — Glorious Gain System — to nudge each point).

The Satyr Trick (see Lockpicking) accelerates training: Discord drops effective skill, lower-skill maps roll gain checks faster, and the Cartographer pumps maps in the discorded state. Also viable: train all the way through World Maps with a Mapmaker partner buying the output back, then push the last 0.5 points on real Treasure Maps.

Roughly 3,000 gold of starter capital covers the 0-100 grind on a Production Shard. Siege and Mugen prices and gold-rarity require a different approach — typically partnering with a wealthy Cartographer who can absorb the loss.

Build context

Strategy notes

  • Decode is one-time. Once a Treasure Map is decoded, the Cartographer's job is done. A guild's high-Cartography character can decode the entire raid's map drops in batch, then any member runs the maps. This is the most common use pattern.
  • GM Cartography saves dig time. The 4-tile radius means landing inside the zone on the first dig attempt rather than searching adjacent tiles. On a 25-chest T-Map session, this is hours of saved real-world time.
  • Trammel/Felucca only for drawing. The other facets reject map drawing — useful sanity check on character location during a multi-facet expedition.
  • GGS is your friend at 99.5+. The Glorious Gain System guarantees a skill point per ~5 hour real-time period if the character has performed at least one gain attempt. Run a daily Treasure Map and let GGS finish the build.
  • Map crafting profit. A 70-99 World Map run on Felucca often pays for itself — the bank-cycle gold loop is tight. Most cartographers report breaking even or making a small profit during 0-100 training.
