We've got to get inside, but the place is crawling with guards. But no need to fight them! Using my amazing powers of stealth, we'll be in and back out before... ...aw crap. So Much for Stealth. In a situation where a character is trying to sneak around unnoticed, their attempt at stealth will suddenly be threatened by them stepping on a dry twig, sneezing, knocking something over, setting off an alarm, blowing their cover, or otherwise alerting others to their presence. If no one notices, they might be okay - in the worst case, they might be captured, or have to face the enemy in a full-blown battle. Either way, heads will turn suddenly.
