What Is Arc Core?
Arc Core is a narrative-first fantasy tabletop roleplaying game set in Ysvara, powered by the Unified Arc d20 System (UAd20). The rules are built to serve the story: every roll, resource, and consequence exists to make choices matter and give weight to what happens at the table.
Why Play Arc Core?
01
Occupations With Their Own Progression
Occupations reflect the life you lived before adventuring. Each has its own six-step progression that runs alongside your Sigil, Caste, and Origin Legacy, so who you were keeps mattering as you grow.
02
Sigils & Castes That Shape Power
Sigils define broad paths of power and purpose, while Castes give them sharp, specific form. Two characters with the same Sigil and Caste can still feel completely different at the table.
03
Origin Legacies That Grow With You
Your Origin Legacy isn’t a throwaway background. It’s a tiered legacy that advances as you level, carrying your history forward instead of leaving it behind.
