And that's how the adventure ended.
(Just kidding, but imagine if I was serious.)
The next EGSNP will be next Tuesday due to Thanksgiving in the US.
Roll To Do Nothing
I don't think I need an excuse for the third panel beyond "it's a silly comic."
If I HAD to make an excuse for it, however, it would simply be that George had to roll to avoid getting hit. By that point, doing nothing wasn't actually an option for avoiding damage.
I'm not sure what sort of roll one would make in any particular game to avoid getting hit by three allies rolling uncontrollably down some stairs, but I'm assuming they'd need to roll high.
