Summy Reliquary

A Seven-Deadly-Sins themed Curios trinkets & weapons mod for Minecraft 1.20.1 / Forge, inspired by The Binding of Isaac and built around an angel path and a demon path.

Features

Starting point: on first join you receive the Source of Sins and the Halo. Each sin has its own trigger condition and grants both buffs and drawbacks once awakened; redeeming a sin keeps only the buff.
Angel path: redeem all seven sins, then convert the Source of Sins into Virtues — Spirit Altar set → Star of Bethlehem → Final Revelation → Godhead. Weapons: Holy Spear and Seraph Spear (extra attack reach, 10% holy-light proc, hold right-click to charge throw with a holy-light burst on impact).
Demon path: get invited in the Soul Sand Valley and sign the pact — The Pact → Ceremonial Robes → Satanic Bible → The Mark → Night Wraith → Brimstone → Abyss Lord → Abaddon. Weapons: Sacrificial Dagger and Dark Arts (the "Shadow Dash" mark-and-slash skill), plus the evil-meter tiers and the Devil Crown. After 666 the angel path is permanently locked.
Two hidden challenges: kill the Ender Dragon without wearing the Source of Sins → "The Sinless"; wearing it with all sins unactivated and an equipped-time percentage of ≥99% → "Flawless".
24 advancements, a one-time Genesis reset item, and the faction-neutral Golden Razor (piercing throw).
Weapon × accessory synergies: dash slashes trigger pact lifesteal & evil gain, empowered slashes trigger the Mark's black-heart burst, contact marks apply one hellfire stack, Abaddon widens the skill, Sacred Heart boosts throw speed ×1.25, Godhead enlarges the impact burst.
