Power Equals Rarity: Difference between revisions

Contrast [[Junk Rare]] and [[Promotional Powerless Piece of Garbage]] for the "rare" and "promo" inversions of this trope. Compare [[Game Breaker]] for a retroactive application of this trope, for when something is so broken you might only be able to use one in a deck/army/etc. Often present in games with [[Level-Locked Loot]]. Related to [[Commonplace Rare]], when a useful item that by all logic ''should'' be easy to get turns out to be extremely difficult.

* ''[[The Dresden Files]]'' justifies this by using explaining that the more people use a certain ritual, the less power one can draw from it. The White Council often publishes texts like the Necronomicon for the sole purpose of robbing them of their power.

* Kevlar is fairly easy to make, but as someone demonstrated on the Discovery channel, heavier weapons (such as a rifle at close range) can pierce the fibers (making it really ''bullet-resistant'' rather than ''bulletproof''). In order to really stand up to bullets, needs a Kevlar with ceramic plating woven in, but to do this sort of thing is more expensive, and thus more rare.

* While stronger life forms tend to out-compete weaker ones within their own species (or niche), small species tend to be more numerous than large ones, and prey tend to be more common than the predators that eat them. This comes down to available energy. A general rule of only 10% of the energy that goes into an organism is transferred to the organism that eats it, the rest is used up by the prey species' own life processes. This limits the amount of energy available to predators thus reducing the possible number of the predator.
