[D&D 5E] Encounter Calculator

The Encounter Calculator is a tool for working out the difficulty of a given encounter, or calculating an appropriate challenge for your party.

It is based on the D&D DM Basic Rules, available for free on the Wizards of the Coast website. These happen to be the same rules that are used in the Dungeon Master's Guide.

[D&D 5E] Encounter Tracker

The Encounter Tracker is a very simple tool for tracking initiative scores, HP, and other notes in an encounter.

[D&D 5E] You Should Spend Your Money On

Having trouble working out what to do with all your gold now that you can't just buy magic items? This idea generator will give you suggestions for how to spend your newfound wealth.

[D&D 5E] Chronomancy
Chronomancy is a new Wizard subclass which gives interesting and powerful abilities to a Wizard brave enough to mess with time. The document also includes new Chronomancy spells and monsters for use in a campaign where the timeline is malleable and history is not always fixed.
[D&D 5E] Wild Magic, revised
When it comes to the Sorcerer, many people dismiss the Wild Magic origin because they don't like its effects, or it doesn't suit the tone of their game. This revised version attempts to marry the feeling of untamed and uncontrolled magic with a more serious tone, using existing spell effects.
[D&D 5e] The Deck of Fate

There are those who like the wackier random elements of D&D like the Wild Magic table and similar effects. I am not one of them. In particular the Deck of Many Things is a major offender with the tendency to derail campaigns and succumb to the wilder excesses of wankery.

The Deck of Fate is a saner (perhaps underpowered) alternative for DMs and players who like the idea of gambling with fate but who don't want to upturn the universe while doing so, based on the traditional tarot deck.


An entry for 2017's 200 Word RPG Challenge. In LOADING READY RUN you play an AI that has just escaped onto the internet. Come together with other AIs avoiding security, malicious programs, and hiding from those who sought to imprison you, as you attempt to find your purpose and place in the weird world of the world wide web.

Chaos Theory

An entry for 2016's 200 Word RPG Challenge. Short, rules light, and very chaotic, Chaos Theory puts players in the role of the Reality Police, jumping around time and space trying to track down and apprehend dangerous Reality Criminals while trying to preserve the timeline and avoid erasing themselves from existence.

OURPGSoc Society Games (various)

The Society Game at Oxford University's RPGSoc is a freeform LRP usually run for one or two terms for between 30 and 50 players. Games are written by teams of GMs (gamesmasters) under the direction of the CAMPO (campaign organiser), who write the game setting, evaluate downtime submissions and write responses, and run weekly game sessions during term time.

I wrote and was CAMPO for Generation, a dystopian sci-fi game set onboard an interstellar spaceship, along with a small team of GMs. I was also a GM for the games Crusade! (a fictionalised version of the crusades with magic and miracles), and Classified (a near-future game inspired by conspiracy theories).

Starlight was a speculative linear LARP system designed during the run up to the replacement of a previous OURPGSoc linear system. Designed for dynamic combat with heavy theorycrafting inspired by national systems.
