If the Cobra agent is adjacent to a hunter (Beast), the hunter throws the dice and gets a 4, and the Cobra is using the Velocity Blade (which takes off -3 from the dice).. Does that still count as a hit, or does the remaining 1 point count as a dice 1, i.e. instant miss?
AFAIK only an actually rolled 1 is considered an automatic miss, so this should be a hit.
That is correct.
Björn is correct.
