Nebula
A nebula is an anomaly that affects movement and combat.
A ship can only move into a nebula if it is the active system.
- A ship cannot move through a nebula. That is, a ship cannot move into and out of a nebula during the same movement.
A ship that begins the “Movement” step of a tactical action in a nebula treats its move value as “1” for the duration of that step.
- Other abilities and effects can increase this number.
If a space combat occurs in a nebula, the defender applies +1 to each combat roll of their ships during that combat.
