Thank you, thank you, I'll be here all week.
Try the beef kebabs and please, tip your waitress.

Three rounds of no attacks and just 1 Defend die really puts the hurt on Chaos Warriors and Gargoyles. Consider changing the 'save' to rolling as many red dice as the monster has Mind Points, requiring a 6 to nullify the spell (and thereafter). After a turn or three of being clobbered the big baddies might shake it off in time, so they can still present a threat and give some payback. Also, undead monsters should be immune- they don't have mind points (or in some cases skin), and thus aren't bothered.
I think Filth spells is just fine as a name for the group- direct and understood by 12-year-olds, just like HQ. No need to dress up unsanitary conditions and bad hygiene with fancy wording.

yeah it is rather stout as written...

good point on the undead

and the uneducated nature of 12 year olds

However, everyone I know who plays RPG's with one exception are over 30 and the one tween in my game circle, well she is the exception to the rule and really is smarter than the adults she hangs with.
