Enchiridion of the Computarchs presents casting mechanics and concepts for high-tech settings. It encompasses a range of material concerning computers and programs that a “techno-caster” (like the MCC shaman class, or those classes found in Netcrawl, Cyber Sprawl Classics, Crawljammer, Umerica, Terror of the Stratosfiend, and Star Crawl) can utilize. You will not only find a collection of programs (aka spells), but also a d24 burndown (aka spellburn) table, new mechanics for spell failure, and a brief corruption table all couched in a high-technobabble style for your post-apocalyptic, far-future, and dystopian-future campaigns.
