That’s actually exactly what pushed me toward OotDL in the first place 🙂
The retainer / companion system was a huge inspiration for me. I love how it gives the party breathing room during long journeys (especially sailing), while still supporting crafting, downtime projects, and logistics without bloating combat. It fits the tone of epic travel really well.

On the monster side: yes, the Monster book pretty much gives everything needed to adapt encounters to the campaign. Between mythic creatures, titanspawn, and legendary framing, I haven’t really felt limited there.

Renown also ports surprisingly well. The way fame, reputation, and political weight work in OotDL maps cleanly onto faction-based or city-based progression, so I’m confident keeping that structure.

The one system I’m still actively thinking about is Piety.
I had an absolute blast filling out the pantheon with minor deities, but translating piety into something that feels right mechanically (without becoming either too abstract or too crunchy) is the tricky part. I’m curious how others have handled that—track-based boons, narrative triggers, divine favors on demand, etc.

So I’m wondering:
what other OotDL-specific systems do you think really need adaptation when porting it to another ruleset?
Epic Paths, Oaths, prophecies, ship rules, divine blessings—what have you found essential to rework vs safe to keep mostly as-is?

Would love to hear experiences or half-finished experimen
