Quickness - Make you attack first, evade traps better, inc. chance to evade ultimate skills
Mostly right, but you always attack first turn in battle, except for when the enemy gets a surprise attack on you.
Also, before I spend the next two hours or so whittling down that sheep, is there any reward for beating her? I'm slowly but surely doing it, but the nearly 20 minutes to take down 10% is more demoralizing than anything the sheep herself does.
