Welcome to Double Proficiency! Here’s a quick list of our in-house projects.
For hired work, see Design and Writing tabs.


Herbalist’s Primer

A system-agnostic tabletop RPG book on real-world magical plants. A mix of science, ethnobotany, folklore, and occult, all prepared and served as an in-game guide for herbalists, alchemists, druids, and game masters.


Project Aphelion

A hard scifi tabletop RPG with modular, easy-to-learn ruleset promoting teamwork and creativity in a setting of a colonized Solar System.


Wayfarer’s Deck

A series of 50-card decks with encounters, wonders, mysteries, puzzles, and findings provides a convenient way of creating engaging situations for the players.


Globetrotter’s Guide to Greenery

A series of 20-page PDFs introduces various biomes, their signature plants, and a handy list of descriptors for all of the senses – now your player characters can not only ‘see’ but also ‘hear’, ‘smell’, ‘taste’, and ‘feel’ the world around them. Devised as a quick reference during the game, each PDF covers one specific type of terrain. 


System-neutral Add-ons

A new series of system-neutral add-ons, created to supplement existing mechanics of any game.

The first one, Duelist, is a combat add-on for tabletop roleplaying games, intended to add depth and variety to a wide range of most popular TTPRG games without replacing their mechanics. Instead, Duelist aims to work with the already existing game systems, to further bring out the fun of combat.


In the works…

Incitatus

A space horror novel.
When a group of young employees of the Zhengdao corporations finds an artifact that may or may not be a dead alien, they find themselves right in the middle of conflicting interests of their bosses, the pirates, the Rangers, and some mercenary crews deeply interested in space archaeology…

A part of the Project Aphelion universe.


Blazing Aurorae

A space fantasy novel.
An imaginative adventure of exploration in the most unfamiliar circumstances. A dash of Slavic culture, a dash of cosmic horror, a lot of solar winds and vibrant aurorae dancing above the characters’ heads.
