Ready-to-use spell rosters for each of the core character classes.
Includes abbreviated descriptions, components, difficulty classes, and so forth.

Monster Monograph
Statistics blocks for every monster in the Core Rules!

a Microsoft Excel Document.

A collection of statistics blocks for all the core creatures that can be conjured by the various "Summon Monster" spells
(generally used by Bards, Clerics, Sorcerers, and Wizards). Runs 19 pages long; in Rich Text Format.
You may also wish to consider the same list of creatures in the shorter "QuickStats" format, here; a 5-page Microsoft Excel Document.

Frequently Asked Questions
Interaction of Armor, Spells, and Items
I've noticed that on a number of online message boards, the same questions about how various protections combine or accumulate are repeated on nearly a daily basis.
This page attempts to explain the general rule concisely, with official page references, and useful examples.
What is the "Caster Level" of a Magic Item?
This article details the surprising confusion around what the listed "caster level" of a magic item really connotes.
Includes references, quotations, and links to all the relevant parties, and a FAQ at the end treating common points in the argument.
Can I Make a New Magic Item?
There are a lot of D&D players who believe they can always invent their own new magic items for their characters.
This page reminds them why that's not the case unless their DM is making exceptions for their characters.

Generic Counters
Generic counters for almost all the different sizes of monsters. Use these if you're tired of
hunting for just the right exotic miniatures or card counters.
Floor Plans to "The Keep on the Borderlands"
Complete floor plans to all the buildings inside D&D Module B2's "The Keep on the Borderlands".
Monster Icons at Scale
This page presents a selection of flat, top-down images at the correct scale for many D&D monsters
(particularly the larger types based on real-life animals and creatures).
I've found them to be quite useful for monsters that would otherwise require large and expensive miniatures, but are rarely used.
Secure Shelter Foldup Model
Does your party use the 4th-level wizard spell leo's secure shelter much?
Then you might find it useful to cut out & set up this scale model of the "sturdy cottage or lodge" that they camp in every night.
Spell Areas on a Grid
This article analyzes the spell-area determination rules in the DMG.
It clarifies and suggests several options, and (best of all) provides spell templates in a ready-to-print format for use in any game.
Gelatinous Cube
How to make the best "gelatinous cube" monster for your game.
Rules Alternatives
Environmental Risks
This paper makes environmental dangers -- falling, drowning, heat & cold, starvation & thirst -- more perilous (and yes, realistic) than in the core rules.
The general strategy is to make damage dice cumulative per increment.
It also documents that this was Gygax's original system for falling, disposed due to a typo in the original Player's Handbook.
These rule guidelines are usable with any version of D&D or AD&D.
Games and Competitions
This short paper presents a suggestion on how to handle in-game contests, competitions, and games.
It includes a new suggested Knowledge skill and specific strategy details for characters playing chess.
Battlesystem d20 Conversions
Conversion rules for using either edition of the Battlesystem mass combat rules with the current edition of D&D.
Superheroic d20 Characters
This is a primer on what the d20 system statistics look like stretched to their wildest limits, as perhaps for a superheroes-type game.
Includes suggestions on how to convert abilities from the Marvel Superheroes game to D&D 3rd Edition.
Marvel Superheroes d20 Characters
Now that there is an official d20-style superhero game, here is a recommendation for how to start converting official Marvel Super Heroes characters to the Mutants & Masterminds game system.
Wild West d20 Characters
Here sits a short paper on how to interface the current D&D system to the 1979 edition of the Boot Hill game.
Just in case you were wondering.
House Rules
The "house rules" used in my personal campaign.
Settings and Campaigns
The Gods of Greyhawk
Here I have a set of short writings summarizing and organizing the different ethnic pantheons in TSR's Greyhawk campaign.
This was inspired by canonical 1st Edition AD&D sources, but should certainly be relevant to 3rd Edition play, in which Greyhawk was re-established as the default D&D setting.
The History of Greyhawk
This page includes a pair of articles drawing conclusions about the history of TSR's Greyhawk campaign, especially with regard to the nonhuman races.
Again, these writings hold scrupulously to the original printing of the Greyhawk setting.
Software
Over the years, I developed quite a number of DOS & Windows programs that I found useful, specific to the 3rd Ed. D&D game. You can see them over at my Software Page.
