System Conversion

Lightweight standalone option

Mar de Oro 2d6 Resolution Bridge

A compact resolution method for groups that want to play Mar de Oro without adopting another complete ruleset. Mar de Oro itself remains system-agnostic.

Begin with the core vessel tracks and range bands from the System-Neutral Adaptation chapter, then express them through the selected ruleset.

How to resolve an action

Roll 2d6 and add a Capability modifier (Familiar 0, Trained +1, Expert +2, Master +3). Read the result on the outcome ladder:

  • 6 or lower: failure with a complication. The fiction changes; progress does not.
  • 7 to 9: partial success at a cost. Choose a cost from the pressure track.
  • 10 to 11: full success. Advance a clock or resolve the beat cleanly.
  • 12 or higher: critical success. Add a benefit; the GM introduces a fresh opportunity.

Pressure and consequences

Use the pressure track and consequences from the System-Agnostic Adaptation chapter. Failure introduces a complication rather than removing progress.

Clocks and extended challenges

Segmented clocks (four, six, or eight segments) track extended challenges: research, chases, infiltration, negotiation, repair, or vessel damage.

Fortera and Overdraw

On a 7 to 9 result while performing a Fortera task, the player may choose Overdraw to convert the partial success into a full success. The cost is strain, instability, or another meaningful consequence chosen by the group.
