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.
A group of humans living in a mountainous area have spent generations mining, drinking home made liquor, and generally not spreading the gene pool around enough. The end result is a sub-race of humans who no longer have necks, rather their heads protrude from the upper portion of the torso between the shoulders. They have beards, and lacking the ability to turn their heads, can only see what they are directly facing. They are simple and to the point, and direct to the point of bluntness.
