That's the achievement that made me stop caring about achievements because of how stupid they are. It's not that I couldn't do it, no, it's that I refuse to do pointless and stupid crap like this (and if you do this crap, ask yourself - if they add another achievement for getting 250 rays on yourself, or, say, an achievement for reaching 50 rays 10 times, etc, will you still do it?).
