Adjustment And Division Of Experience Points (p.84) 
| The vanilla DMG’s treatment of XP adjustment and division is more candid than the rest of its experience model — it acknowledges GM judgment, contextual factors, and the circumstances of award in ways that the kill-and-loot formula does not. That candor is the honest core of how XP has always worked at every table that ran it well. |
Oath-Bound completes that thought. XP is awarded solely by the GM at the Session Journal — honestly, transparently, and collaboratively. There is no formula. There is no prescribed award for kills, treasure, or any other enumerated activity. The GM’s judgment, informed by the session’s events and the table’s collective account of what happened, is the instrument. The vanilla section’s acknowledgment of contextual judgment is not a caveat to the formula — in Oath-Bound it is the model.

Experience Value Of Treasure Taken (p.85) 
Superseded. Treasure has no prescribed XP value in Oath-Bound. Finding, taking, or spending treasure is part of the fiction. Whether it contributed to meaningful development is a judgment the GM makes at the Session Journal, not a calculation applied at the point of acquisition.

Special Bonus Award To Experience Points (p.85)
Superseded. Discrete bonus XP categories — for prime requisites, exceptional play, and similar — do not exist in Oath-Bound. The GM’s award at the Session Journal encompasses everything. A session of exceptional engagement is reflected in the award without requiring a separate bonus structure.
See Advancement.
Gaining Experience Levels (p.86)
Superseded. The vanilla level gain procedure — reaching a threshold, paying training costs, receiving the level’s mechanical benefits — does not apply. In Oath-Bound a character does not level up. They arrive at a point where they are functioning at a new level. The level is a recognition of what the fiction already established, not an event.
The XP threshold structure of vanilla AD&D remains intact underneath. What changes is how those thresholds are reached and what it means when they are.
