So, tonight in our game, we were in an underwater situation. The rules seem to say that you can hold your breathe for 3 min without checks. Then if you have a "strenuous activity" or take damage, you need to make an endurance check DC 20. I found this interesting since in our situation, we were able to swim, get into combat, etc. without checks, but when I picked a lock, THAT was a strenuous activity. I tried looking in the rules about what this exactly is, but couldn't find it anywhere. We basically determined that it was DM's decision what is "strenuous." Personally, I find swimming and swinging a sword more strenuous than lock picking, but I wish there was a rule about this. I mean, are all skill checks "stenuous" then? Thoughts?
