House rule:
When you want to do something - make a skill check, use a power, a basic attack, whatever - you have to describe what you're doing and how it works "in world". If the DM thinks your description is beyond stupid, then you can't do it.
However, if you don't have a power that describes what you're trying to do, but your description makes sense "in world", you'll get to roll for it. Page 42 is our guide to resolving your action.
Basically shifting responsibility from explaining this stuff from the DM to the player, and keeping the focus on "in world" stuff.
