Hex Areas

A lot of gamers use hex paper for maps, battle schematics, etc. Hexes are usually defined by how far across they are from one flat side to another. This is great for most purposes. Occasionally, however, you want to know the area of a set of hexagons. The formula, unfortunately, is a bit daunting for the non-mathematically inclined. Here's a simple table showing the area of various hex sizes:

Distance across hex Area of hex (rounded)
1 1
2 3
3 8
4 14
5 22
6 31
7 42
8 55
9 70
10 87
15 195
20 346
25 541
30 779
35 1061
40 1386
42 1528
45 1754
50 2165
75 4871
100 8660
125 13532
150 19486
175 26522
200 34641
250 54127
500 216506
1000 866025

The formula, in case you want to insert values that aren't on the table or want exact values, is: (6tan30*Distance^2) / 4.

Weights of Common Substances

Compiled by Andrew Roy The table below provides density figures for many common (and some not-so-common) substances. This information is useful for determining the weight (or volume) of objects and cargo. This table was pieced together from a wide variety of sources, listed in full at the bottom of the page. The inspiration for this comes from the old Dragon magazine article, "How Heavy is My Giant". These figures have not been rigorously checked. Do not rely on this as a scientific reference! Note on measures: Specific gravity is a measure of an object's density. A cubic centimeter of water at 4°C weighs 1 gram, and has a specific gravity of 1. The specific gravity numbers below can be read as "grams per cubic centimeter" (or kg/liter). A solid object with a specific gravity greater than 1 will sink in water. Weight in pounds per cubic inch and foot is also provided to save non-metric users some time on the calculator. Material Specific Gravity Pound...

Very useful Caves of Chaos map

When it comes to dungeon maps, I favor utility over artistry. Maps with rendered furniture and torchlight shadows are nice, but if they’re only seen by the GM, they’re not very practical. I want maps that are clear and make layout with dungeon tiles easy. If they can convey additional information without being too busy, all the better. Given the above, I really like this map of the venerable “Caves of Chaos” I found on The RPG Cartography blog . Not only is it practical but it contains a lot of useful information without being overdone. The only thing it’s really lacking is a square grid, though that might have clashed too much with the other elements (maybe tick marks on the outside of the walls could have been substituted...?). I’m not sure how much use I’ll get out of this map, but it’ll definitely be a model for ones I make myself in the future. (Note: The first link is to a JPG of the map, but the PDF you can download from the second link is much higher quality).

OSE Players Companion

For a variety of reasons, I've switched from 5E to Old School Essentials . To that end, I've created a PDF for using Mythosa with OSE, including house rules, what optional rules are used, and similar things. The PDF is available from the Downloads page.
