As my group has played it, the group as a whole takes 1 hit for the initial attack that may kill 1 or more individuals in the group (just like a regular attack). If you've got a bunch of advantages or if the GM just plain says so (tossing a grenade into an elevator full of stormtroopers, for instance), you can trigger Blast to hit other individuals in the group - if it's logical for the explosion to encompass additional individuals - adding additional wounds against the group's wound threshold.

I wouldn't have thought you could trigger Blast more times than there are additional members of the group (if there were only two stormtroopers in that elevator, I would have thought you could only trigger Blast once).

Blast and Minions

Question asked by Darth Pseudonym:

Should a group of minions be treated as a group of individuals who happen to share one wound pool, or as a single entity?

That is to say, if a blast goes off in the middle of a group of minions

-- should each minion, individually, take the blast damage, soak it, and apply the remainder to their shared pool, or

-- does the group as a whole get hit by the blast, take the damage, soak it once, and then apply the remainder (and if so, then does the group being the primary target exclude the group from being affected by the blast)?

Or is there some other methodology?

Answered by Sam Stewart:

The first option would be more thematically appropriate. That being said, if the minions were particularly spread out (if you had a group of four with two each behind two separate barricades, for example), I'd rule that some of the minions couldn't be hit by the blast damage. It does make grenades quite effective against minion groups; but that's sort of the idea in any case.
