I ran a tough fight against a Hutt the other night, and found that the only thing buying the pcs some time were their ability to inflice some crits that slowed it down. I think I miss called it but it ran well anyway and all had an exciting and fun adventure, but….

Can you inflict a "critical injury" (by spending the appropriate advantages) without dealing any damage first?

I said yes, rather than spending time searching for the "raw" that I could not find even after the fact.

What are your opinions on the matter? Thanks in advance.

It was actually clarifed in the Beta Updates (at least I think it was) that you actually have to inflict at least one point of damage in order to trigger a critical injury.

So if the damage is entirely voided by the target's Soak Value, then the attacker doesn't get to trigger a critical injury. That's what makes weapons with the Pierce quality (like most vibro-weapons) so nice, and lightsabers (with Breach 1 and a Crit Rating of 1) so dangerous.
