Absolutely, Steven. Here's a fully rewritten, epic and original description for your artifact—designed to preserve every mechanical detail while elevating the tone, doctrine flavor, and cinematic impact. This version avoids copyright conflicts and makes it fully shareable in D&D Beyond:

📘 Codex of Ascendant Light

Wondrous Item, Artifact (requires attunement by a creature of good alignment)

Forged in the crucible of celestial truth, the Codex of Ascendant Light is a divine manuscript that transcends faith, race, and realm. It is not a scripture of dogma, but a living doctrine—etched by the hands of exalted beings who glimpsed the multiverse’s purest virtues and dared to record them. The codex does not remain in one place for long; it vanishes from the hands of the righteous only to reappear where darkness festers and virtue must rise again.

Bound in platinum-threaded leather and sealed by a clasp shaped like angelic wings, the codex can only be opened by a creature of good alignment who has attuned to its essence. Once opened, the reader must devote 80 hours of uninterrupted study to absorb its truths. Only then may they attempt to unlock its power.

📖 Study and Consequence

After completing the study, the attuned creature must succeed on a DC 25 Intelligence (Arcana) check to comprehend the codex’s divine architecture.

• On failure: The reader suffers 24d6 radiant damage, bypassing all resistances and immunities. If reduced to 0 hit points, the creature is obliterated in a flash of divine light, leaving only their possessions behind.
• On success: The codex’s power floods the reader, granting the following permanent benefits:

✨ Divine Boons

🧠 Wisdom of the Ascendant

Your Wisdom score increases by 2, to a maximum of 24. This benefit can only be gained once.

🔮 Enlightened Magic

Whenever you expend a spell slot to cast a cleric or paladin spell, it counts as a slot one level higher.

👼 Halo of Virtue

You manifest a radiant halo that sheds bright light in a 10-foot radius and dim light for an additional 10 feet. You may dismiss or summon the halo as a bonus action. While active:

• You gain advantage on Charisma (Persuasion) checks against good-aligned creatures.
• You gain advantage on Charisma (Intimidation) checks against evil-aligned creatures.
• Fiends and undead within the halo’s bright light have disadvantage on attack rolls against you.

🔱 Embedded Properties

Minor Beneficial Properties

• Swift Grace: Your walking speed increases by 10 feet.
• Radiant Resistance: You gain resistance to radiant damage.

Major Beneficial Properties

• Wings of Virtue: You gain a flying speed equal to your walking speed.
• Surge of Purpose: Once per day, you may take one additional action on your turn. This action can be used to Dash, Disengage, Attack (one weapon attack), Use an Object, or cast a spell. You regain this ability after finishing a long rest.

⚖️ Moral Clause

The codex’s gifts are not unconditional. If you fail to perform an act of kindness or generosity within 10 days, or if you willingly commit an evil act, all benefits granted by the codex are lost until you atone through a significant act of virtue.

💀 Destruction

The Codex of Ascendant Light cannot be destroyed while good exists in the multiverse. However, if submerged in the River Styx, its divine essence is erased, rendering it powerless for 1d100 years.

Let me know if you'd like a doctrine mutation pack or cinematic encounter built around this artifact. We could trigger radiant bursts, NPC reactions, or session shifts based on halo activation, moral upkeep, or extra action usage. Ready to build the reactive layer?
