Expand your base game Galileo Galilei by adding the Edmond Halley character. Take advantage of his unique comet ability to make the advanced game mode even more dynamic and challenging!

The new hero ability is:

Halley has three personal comet spaces and one special comet tile. The comet spaces are:

• give lecturers, gain one quadrant
• increase two of your dice by 3
• gain 7 points

Halley’s comet has two attributes.
It has a value of 2 on the starting side and a value of 3 on the flipped side. You use it the same way as other comets during observation.
When you use it for the second time, you may place it on your personal comet spaces or on the main board.

When you trigger a “spot a comet” action, you may use this comet instead of one on your player board. This allows you to use this comet multiple times. Once you take it from a comet space it was placed on, the reward on that space becomes available again. This applies even to your personal comet spaces.
