## Rules questions

### Does an Omega component add to the original, or replace it?

It replaces the preexisting component with the same name and type; use one version, not both (p. 8).

### When I resolve Diplomacy, do I refresh every planet in one system?

No. The primary ability lets you refresh any two of your planets, not every planet in a chosen system (p. 14).

### When do units roll for a gravity rift, and what happens if they fail?

Units roll as they pass through the rift. Units that fail are returned to their owners’ reinforcements, not destroyed, so destruction-triggered abilities do not resolve (p. 14).

### Do I have to move infantry off planets before retreating?

No. When a ship moves as part of a retreat, it can transport ground forces from planets in its system as normal (p. 14).

### Do I have to decide whether to reroll each die immediately after rolling it?

No. Roll dice for all your units in the combat first, then decide which, if any, to reroll (p. 14).

### In the Ordinian scenario, how do I take control of the Coatl, and what does repairing it do?

You control it while you are the only player with ships in its system, and lose control if you no longer have ships there. At the start of your turn, if you control it, you may spend 6 resources to repair it; it then awards its controller 1 victory point and adds the agenda phase to the game (p. 12).
