MANCER Core Rulebook - Alpha In Development
A downloadable tabletop RPG
DISCLAIMER: The book contains some depictions of scantily clad anime girls, blood & gore - nothing too explicit, but not all-ages either.
***
MANCER is a tabletop RPG about:
ANTEDILUVIAN ADVENTURES
Delve into the world of Vestige, an post-apocalypse fantasy setting blending a myriad of influences from mythology, world religions & conspiracy theories.
You play as a Mancer, a mage from one of the surviving mortal realms on Vestige after the Great Flood. Set forth into the primordial chaos of the deluge, where divine corpses lie rich for the plunder.
Carve these ancient bones into your wands; drain their ichor to create elixirs; skin them to make your robes. But take care, NMEs - Non-Mortal Entities like dragons & demons - skulk through the Flood, hungering for sport & blood.
MAGIC & TACTICS
MANCER's game system is currently being rebuilt using the Voyager system as its base, which is my original RPG system I'll be using for future projects moving forward. (the current public build uses a mix of Year Zero Engine and Lancer until development resumes on Mancer).
FEATURES
- 100+ pages of content (with more to come).
- Six playable races: Human, Elf, Drakeling, Fiendling, Homunculus & Wight.
- 9 Mancer archetypes: Magus, Sorcerer, Hierophant, Psychic, Druid, Alchymer, Ravener, Witch & Mantler.
- Earn & don Regalia: magical suits made from divine viscera.
- Customise your Regalia with a modular gear system, from numismatic holy weapons to engraved sigils & of course, lots of spells (upcoming).
- Detailed lore about the setting of Vestige - cultures to create character backgrounds in, cities to visit and named figures to interact with.
- An artbook section featuring numerous illustrations and sketches to immerse you into the setting of Vestige to stir ideas for your game
>>ITCHFUNDING
Itchfunding is an alternative to typical crowdfunding methods like Kickstarter and is more flexible and less stressful for creators. Unlike Kickstarter, there's no hard endpoint for the campaign or risk the funding will fail. The campaign remains open and the book remains in development until the funding goals are met.
You aren't funding a final product (though you will get a release PDF if you fund the game), but you're funding the development and progress of MANCER. If you can't afford it yet, feel free to grab a community copy when it's available as support! New free copies will come out often, which hopefully can build a community to sustain MANCER's development till completion.
MANCER is in active development. Your purchase gets you the in-development PDF version of MANCER and any and all future updates. Any payments you make go toward improving the book with art and content. This development version is cheaper, with the final product expected to be $20 at release.
When each funding goal is hit, the PDF will be updated to match. More funding goals will be added as they are met and I get a better sense for what more the game needs, such as art and layout.

FAQ
Is this related to Our Spell Is Steel?
MANCER is an evolution/development on the setting for Our Spell Is Steel (OSIS), combined with the setting of the (warning: NSFW) Project WAND visual novel series. For all intents and purposes, it's the 2nd Edition of OSIS.
Do I need to play OSIS or Project WAND to understand MANCER?
No. MANCER's setting is nearly identical to OSIS + WAND, but with a lot of lore reshuffled and adjusted so I could expand on it more. OSIS still has lots of cool art and a dope magic system, so I still recommend it if you're into the whole anime magecore dark fantasy aesthetic. And if you like steamy yuri, WAND is definitely for you.
