Typhn's Bones to Jelly

Using an Action, you may imbue yourself or others some qualities of the resilient oozes. To you temporarily transform the target's bones and internal functions into a gelatin replica. They function as normal but are far more malleable and elastic. The creature gains the following effects:
They can fit in spaces two sizes smaller than them.
They gain immunity to fall damage.
And they gain immunity to non-magical bludgeoning damage.
 
However this magic is not perfect, and it makes walking a little more difficult then it could be, and thus the target's movement speed is cut in half.
