Has anyone tried the Horde rules from Deathwatch in a Dark Heresy game? Any thoughts on how well it adapts?
I set my players against a 40 magnitude giant rat horde to try out the rules. I thought it all worked pretty well except the rules for damage from hordes. The horde only managed to hit one acolyte once before it broke. The problem I have is that the one hit it dealt out 18 damage (3d10+2), I think that’s too much for one lucky shot.
I am thinking about changing the extra damage die for magnitude to extra attacks based on magnitude. More chances to hit and each hit deals out a reasonable amount of damage. I was also thinking about adding a "dumb luck" rule that lets the attack either bypass armor on a damage roll of 10 or that duplicates righteous fury so that there is still a real threat from the horde.
