So for Christmas I got the Legend of the Five Rings 3rd Edition book. Nerrrrrrrd. Anyway, apparently "Getting out of bed" is an example of a mundane action that you'd only have to roll Difficulty 5 for. Shouldn't that really be an automatic action? What does it mean if you fail to get out of bed? Do you get to try again later? What kind of skill would you use for this?
In conclusion, this seems like the kind of oversight that would be fun to abuse as a GM. So don't let me run L5R for a while, OK? For your own benefit.
Also: if you have problems with this, here are some tips for getting out of bed. Apparently this is a major problem. Here are basic instructions, in case you forgot.
