Wow.
You know what? I'm sorry I offered my opinion.
Watching some of you fall over yourself to defend it is just sad.
Like Gimmel, you're right, you can emphasize just the "can." And you're even right that you can use the bag of tricks for something other than combat.
But you have COMPLETELY MISSED THE POINT. The point being that in previous editions the gray bag of tricks was not a combat item, and now it is. Sure, it can be used for non-combat purposes -- so can a sword! -- but the rules as written and the description given, lead one to view the 4e gray bag of tricks as a combat item first and foremost.
The point being that an item that would cause uncreative and unintelligent players to piss and moan and complain that the DM never gives good treasure (and in my twenty years of gaming, I've seen that MANY times), has been changed to make that player -- the worst sort of player -- happy. And that is part of broader trend in 4E to make everything rock simple and plainly obvious, so that the dull-witted players don't have to worry about their brains overheating figuring out what to do with it.
But in making that point, you have become sufficiently pedantic and obnoxious that you made it onto my ignore list, and have caused me to walk away from this thread with a low opinion of the intelligence and intellectual capacities of those who have jumped onto the 4E "stupid is better!" bandwagon.
Seriously, the arguments being presented in this thread are sad.
Throwing a tomcat at someone as an effective combat manuever? That's idiotic. A tomcat, even a big mean tomcat -- and I should know, my parents have a 28 pound Maine Coon tom with a temper -- would be completely ineffective against an armed man with any sort of armor. Even without armor, the scratches would be so insignificant as to be a joke. The idea that a tomcat could TRIP a grown man in combat is equally ridiculous. it's like someone took a joke about cats (how they're always underfoot) and applied it to combat, while ignoring the fact that in the heat of combat a person is a lot more likely to simply crush the cat underfoot, boot it away, and is likely moving quickly enough that the cat's woulkd end up with a lot of broken ribs if it got in that humanoid's way.
That's just dumb.
This is why I hate edition wars so much. People just leave common sense at the door is a desperate attempt to defend dumb things.
