The most accessible navigation technique; accuracy degrades over long distances without correction. | | Stellar Fixes | Precise positional calculations derived from sextant observations of celestial bodies. Highly accurate but require clear skies and reference tables. | | Route Plans | Detailed course charts with annotated waypoints, hazard markers, estimated travel times, and contingency routes. Used to brief crews, guide overland expeditions, or file with port authorities. | | Navigational Charts | Original sea, river, or aerial charts produced from accumulated personal observations. The most lasting and sellable product of navigational expertise. | | Enchanted Navigation Aids | Compasses, charts, or instruments magically attuned to always point toward a specific location, person, or planar feature. Among the most valuable navigational tools. | ### Ingredient Types | **Ingredients** | **Description** | | --- | --- | | 🞛 Compiled Observation Data | Recorded bearings, depth soundings, current notes, landmark triangulations, and celestial measurements gathered through direct observation. The quality of a chart or plot is bounded entirely by the quality of data that underlies it. | | 🞚 Raw Materials | Blank charts, parchment, vellum, drafting inks, and instrument components. The physical medium through which navigation work is documented and communicated. | | 🞜 Astronomical & Mathematical References | Precise ephemeris tables, logarithm tables, tide tables, and harmonic constants. Errors in reference data propagate through every calculation made from them — an outdated almanac is worse than none. | ### Creation Cost & Time | **Navigator Level** | **Creation Slots** | | --- | --- | | Level 0 –<br>Novice | 1 | | Level 1 –<br>Intermediate | 2 | | Level 2 –<br>Advanced | 3 | | Level 3 –<br>Superior | 4 | | Level 4 –<br>Master | 5 | All creation slots are utilized over an 8 hour period. | **Rarity** | **Navigation DC** | **Navigation Die** | **Slot Cost** | | --- | --- | --- | --- | | Common | 10 | 1d4 | 1 | | Uncommon | 15 | 1d6 | 1 | | Rare | 20 | 1d8 | 2 | | Very Rare | 25 | 1d10 | 3 | | Legendary | 30 | 1d12 | 4 | ### Performing Navigation > [!faq]- Navigation Creation Example > To produce a ***Verified Sea Chart of the Stormreach Passage***, an Uncommon navigational chart that grants advantage on Wisdom (Survival) checks made to navigate the Stormreach Passage and identifies all known reefs, shoals, and seasonal current patterns, follow the steps below: > > **1. Gather ingredients** > The ingredients for a Verified Sea Chart are: > 🞜 Current Tide Tables & Stellar Ephemeris (Reference) > 🞛 Compiled Passage Survey Notes (Observation Data) > 🞚 Heavy Vellum Chart Sheet & Drafting Ink > For this example, we'll assume current tide tables have been purchased at a port authority or navigator's guild. > > **2. Roll a navigation check to determine the accuracy and completeness of the chart.** > The DC is equal to... > *the rarity of the creation* — *your navigator level* — *your [[Abilities#Intelligence|Intelligence]] modifier* (minimum of 0) — *your proficiency bonus* (only if proficient with Navigator's Tools) > - Upon success, you waste no materials and the chart is accurate and clearly presented. > - Upon [[#Failing A Navigation Check|failure]], you waste materials and the process takes longer. > > **3. Compile the observations.** > In this case, you succeed and now need to consolidate ***Passage Survey Notes*** from prior traversals of the route, which costs 1d6 *Survey Sketches or Log Entries* — *Intelligence modifier* (minimum of 0) per chart. > > **4. Add remaining ingredients.** > All other listed ingredients are consumed at a 1-to-1 ratio unless otherwise stated. > In this example, 1 Heavy Vellum Chart Sheet and 1 set of Drafting Inks are consumed. ### Failing A Navigation Check On a failed navigation check, roll a *navigation die* — *your navigator level* to see how many ingredients are lost (resulting in a minimum of 1). You must roll separately for both *compiled observation data* and *raw materials*. For time wasted (resulting in a minimum of 1 hour), roll a *navigation die* — *your proficiency bonus* (only if you are proficient with Navigator's Tools). > [!note] > A chart produced on a catastrophically failed navigation check may contain deliberate-seeming errors indistinguishable from intentional misdirection. The navigator does not know the chart is inaccurate until it is used in the field. ## Recipes Navigational methods are formalized within maritime academies and the personal journals of experienced pilots. Known reference works include: - *The Pilot's Handbook* — Foundational dead reckoning, stellar fixing, and standard chart production. - *Stars and Ley Lines: Advanced Navigation* — Celestial calculation, enchanted instrument construction, and planar navigation techniques.
