A chilling wind whips through the hollow. Winter's bite grips your spine. The very air you breath stings. Snow swirls all around you, yet, the trees... the trees are motionless in the gale, unaffected by the cold, biting winds.
Chekov's Spell -- This spell has a two-fold effect. The first is to make the target item almost-unnoticeable to anyone not specifically looking for it. The second is that someone who has seen the item will remember it when they encounter a situation that would be perfectly solved by use of said item.
