CCZ hazards roll in case that would give me any info on these critters: Int 3 + CCZ Hazards 3 (6d6.hits(5)=3)
Intuition roll to estimate mischief size: Int 3 (3d6.hits(5)=1), success but glitch.
I'm assuming these things are moving fine in the dark?
You've heard stories about things called rockrats that live in abandoned buildings eating plascrete until they secrete it out of their skin. Seems like a good fit. You estimate that there's a bunch of these things swarming around. Maybe 30. They don't seem to be running into anything.
Full Def Interp Yo.
rollin': http://invisiblecastle.com/roller/view/3001888/ 6 hits
6 hits will do it. You've still got a free action from the first pass if you want to do anything with it.
Swarm only has 1IP. so feel free to post up another action phase as well.
Ten, Guard can take both passes as well.
RULES FOR ATTACKING A GROUP OF CREATURES
The term used for a group of individually small critters is a Mischief. You are currently balls-deep in a mischief.
A mischief acts as a single entity and is buffed up by its numbers. Rather than a bunch of smaller organisms, it is counted as a larger, more powerful organism, and this power is determined by the number of creatures which make it up.
To kill a mischief, you can either attack directly or try to kill individual members.
Individual attacks against mischief members will do damage to a creature and kill it or not as normal based on its stats.
Direct attacks against the mischief as a whole will kill one mischief member for every 4 damage done. Area attacks will kill a member for every 2 damage done. Either way, success is determined by rolls based on the mischief's strength of numbers.
As a house rule, I will allow multiple attacks to be made against the same mischief with a single shotgun blast. So, since a shotgun on wide choke can usually target 3 people with the same shot, doing so against a mischief would count as three separate attacks, each of which would be dodged and soaked with the -2DV and +9AP that a wide choke causes with fletchettes. Medium choke would count as two attacks, etc. You get the drift. Anything which can hit more than one target with a single roll counts as multiple attacks.
