The Nerd WhoFell to Earth
Before I do tell you let me warn you of something called conformation bias, where you THINK someone is lucky so you only remember good rolls, or think someone unlucky and only remember bad ones...but both have the same random luck.
This was my impression too. One of the guys in my group has a reputation among the others for being very lucky. But it's a mix of confirmation bias (We fondly recall the time he critted and killed a main villain right after he opened a Christmas present--a giant d20 that flashes on a crit.) and he's a powergamer who creates incredibly able characters (especially in comparison to the rest of the group).
