Dysfunctional Rules VIII: When General Trumps Specific

The Silver Key has the following ability:

Cunning Body (Su): By 6th level, a silver key's form has developed the ability to adapt to a number of dangerous environments:

If submerged in liquid, you automatically activate a water breathing effect.
If you fall more than 5 feet, you automatically activate a feather fall effect.
If you are paralyzed, you automatically activate a remove paralysis effect.

The interesting part is where you gain the water breathing even if you aren't submerged in water. A Silver Key who jumps into molten steel, for example, will waste one of his uses of this ability.

Only humanoids can be Stoneblessed.

Human heritage: your human ancestry is from a Shapechanging wizard with particular fetishes. Alternatively, take the entropic and half-troll templates.
