Luck I'd bet! Storing luck with Feruchemy can make you less likely to be involved in important events, the reverse is true when you draw on it. Also:rolling dice or spinning weapons ala Matt (Towers of Midnight) to decide where to go sounds like a very Hoidish thing to do.Edit: actually, that would be an Atium piercing wouldn't it? Oh well, for all we know, he might have one of those too.
