Catalyst Question (tyranids)

[Guest]

Okay, cast Catalyst on one of my bug units. Say, Genestealers. They get hit by a weapon that deals 3 damage. They fail their saves. They have 1 wound each. How many times do I roll on Catalyst? And why?

One of those rules I thought I understood, but recently have been informed works another way, and now I'm uncertain.

You make the Catalyst roll three times for each Stealer that was Wounded. They have to ignore all three points of damage to not die.

So it doesn't matter that the Stealer only has one wound?

Nope, it doesn't matter. Excess damage from an attack is only lost once the Model is removed as a casualty. It's the very last part of the last step in the Resolve Attacks sequence in the main Rules.
