Familiar Arcana TTRPG Deeper Magic. Sharper DnD 5e Combat.
Familiar Arcana is a DnD 5th Edition inspired tactical fantasy tabletop roleplaying game. Experience the d20 system you know, enhanced with richer customization, cinematic moments, and streamlined rules for Game Masters.
A Complete DnD 5e Alternative TTRPG Framework
Familiar Arcana is built from the foundations of classic DnD 5e fantasy. It is not just a minor adjustment. It is a fully realized system designed to give players more agency in combat and Game Masters better tools behind the screen.
The Core You Know, The Depth You Want: If you know how to roll a twenty-sided die and add a modifier, you already know how to play Familiar Arcana. We kept the beloved advantage/disadvantage mechanics, the standard 6 ability scores, and the familiar action economy. Then, we upgraded the mechanics surrounding them; introducing spell points, tactical martial skills, and exhaustion-based death saves.
Familiar Rules.
Better Decisions.
Familiar Arcana keeps the d20 rhythm of 5e, then changes the parts that most often make combat passive, binary, or harder to run than they need to be.
No Saving Throws
Offensive abilities roll against AC, Reflex, Will, or Cognitive Defense, so the acting player stays engaged and every stat has a clear defensive purpose.
Skills Belong in Combat
Martial characters use combat skills for pressure, movement, control, and utility instead of spending every turn repeating the same attack.
Partial Hits Keep Turns Moving
Many attacks can still produce a lesser result when they narrowly miss, making combat less binary without making accuracy meaningless.
Built for the GM Too
Encounter math, monster scaling, Roll20-friendly formatting, and faster rules handling are designed to reduce work behind the screen.
Getting Dropped Does Not Mean You Stop Playing.
At zero hit points, your hero can keep acting, but doing so pushes them deeper into exhaustion. Staying in the fight becomes a choice with an escalating cost, instead of a death-save minigame where your turn often disappears.
One Ruleset, Different Kinds of Campaign
Change the assumptions around progression, magic, and danger without learning a different game.

High magic, powerful loot, and monsters that scale with the party so the campaign can safely become larger than life.

Distinct Classes With Their Own Job in the Party
The base game starts with five distinct foundations. Expansion classes push the system into stranger, more specialized fantasies.
Four Ideas Sit Beneath Every Spell
Schools tell you what magic does. Aspects tell you what kind of idea the magic is built from.
Passion
Passion turns emotion into force. Anger can become flame, devotion can become light, and inspiration can become the spark that pushes someone beyond their limits.
Evocation & Enchantment
Virtue
Virtue gives magic a purpose. It protects, restores, reveals what is hidden, and rewards casters who turn conviction and responsibility into action.
Abjuration & Divination
Corruption
Corruption treats decay and deception as tools of creation. It changes what people see, remember, fear, and sometimes what remains after life has ended.
Illusion & Necromancy
Growth
Growth is magic through change. It mends flesh, reshapes living things, awakens the natural world, and turns existing life into something new.
Transmutation & ConjurationMagic Is Something You Manage, Find, and Build Around
Familiar Arcana pushes magic into the rest of the game instead of keeping it isolated on a spell sheet. Casting, treasure, and equipment all interact with the same magical economy.
Spell Points
Cast from a flexible pool instead of preparing around rigid slots. Spend power where the moment needs it.
Magical Gems
Gems can be treasure, currency, magical fuel, or an emergency resource, giving magic a place in exploration and the campaign economy.
Glyph Crafting
Improve the weapon or item your character already cares about instead of replacing it every few levels just because the numbers went up.
Control Should Change a Turn, Not Delete It
Conditions in Familiar Arcana are designed to matter without leaving a player stuck watching several rounds happen around them. Powerful effects create tactical problems, but the game keeps asking the affected character to play.

Frequently Asked Questions
Is Familiar Arcana compatible with DnD 5e?
It is heavily inspired by DnD 5e, so the basic d20 language is familiar. Familiar Arcana is still its own framework with separate balance, classes, defenses, and combat mechanics.
Do I need to learn a whole new system?
No. If you know ability scores, modifiers, advantage, disadvantage, attacks, and the basic action economy, the foundation will already feel familiar.
Can I use Roll20?
Yes. Familiar Arcana content is written to be easy to move into Roll20 sheets and macros for online play.
What makes combat different?
No saving throws, attack-based defenses, partial hits, martial combat skills, shorter conditions, and exhaustion-based death mechanics all change how turns resolve.
Is this for new players or experienced players?
Both. The recognizable core lowers the learning curve, while the extra tactical systems give experienced groups more to work with.
