'FFFFFFF' Moments in Video Gaming

Battle Tower in Pokemon Emerald.

Going on a pretty good win streak. Next fight, my Starmie versus Flareon. Easy one shot right? Just surf and...

SUDDENLY QUICK CLAW
SHADOW BALL
ONE HIT KO
*screwed because of 3v2 and the rest of the opposing team is of types that Starmie was supposed to cover*

Win streak ended. Back to square one. Because of a single proc of Quick Claw.
