Kind of a strange sentence so I’ll explain further. Imagine you have a baseball that you toss in an arc. At any point you can activate the power to teleport. The location you arrive at will be one where the ball will strike your palm in the next fraction of a second. Hence making you “catch” it.
The power cannot activate if the ball strikes a solid surface, or if the space you are teleporting to is not empty.
Additionally, the ball must be propelled by your hand directly. Balls hit with bats or rackets do not count.
The ball itself must be at least 2.5 grams and have a density of at least 0.08 g/cm^3. That’s roughly the measurements of a pingpong ball, for reference.
“Ball” here does not mean perfect sphere, only a roughly spherical object. A lemon would count, but not a frisbee, for example.
Finally, no matter your orientation when you begin the teleportation, you will always end it standing upright. That is taken into account when determining if there is enough empty space to teleport.
