All you have to do is step in front of the thing. The bead travels at high speeds, yes, but it also must travel in a straight line. It would be no different than intercepting an arrow attack with your body because your buddy is low on hit points.
I wouldn't say that unless I was in the house rules forum, but hey, that's just me.Seriously though, I don't think adhoc rules are necessary here. You can already do this within the rules, and to top it off, it's fully supported. If you can get in front of the bead within a partial action, then it isn't a big deal at all, not for me anyway.
Hey, if the rules say: "You can take an arrow for some one else if you have a readied action", I would go with that. I don't remember it in the rules. Do you have a page reference? I know the 1st level ability of devoted defender allows the character to take attacks their charge. That is the closest I know of.
