We had a situation arise today during a game that we could not resolve.

CR90 rams a Demolisher, and in so doing lands on an Asteroid. Which triggers first, the ram or the Asteroid?

In this case, Reikan settled it in favor of the CR90 (he got the damage on the Demolisher), but if he had been killed by the Asteroid would the Demolisher have taken damage?

If you overlap multiple obstacles, you can resolve those obstacles in any order.

Such as an Asteroid and the Station - Either way around... But of course, that's no help when a Ship is involved, so:

(And I will paraphrase the rules advice given previously, which could be found with a search, but probably not readily now... But it is there)

If you ram a Ship and an Obstacle, then you do the damage for the RAM of the SHIP - FIRST. As it happens as part of doing said maneuver.

The Obstacle overlap happens after that, after you have finished said maneuver.

Ah, I see. So my opponent was right. Fair enough. I'll let him know, and keep that in mind in the future.
