Cypher System Rulebook 1e
A bit translucent, you're slightly out of phase and can move through solid objects.
You can slowly pass through physical barriers at a rate of 1 inch (2.5 cm) per round (minimum of one round to pass through any barrier). You can't act (other than moving) or perceive anything until you pass entirely through the barrier. You can't pass through energy barriers.
You can change your phase so that some attacks pass through you harmlessly. For the next ten minutes, you gain an asset to your Speed defense tasks, but during this time you lose any benefit from armor you wear.
Action to initiate.
The attack you make on this turn ignores your foe's armor. The ability works for whatever kind of attack you use (melee, ranged, energy, and so on).
or
You can phase into a solid object's surface and then phase out of any other solid object within long range of the first, even if the two objects are not connected. There must be no intervening barriers between the two objects, and you must be aware of or able to see the destination object.
For the next ten minutes, you gain an asset to sneaking tasks. During this time, you can move through solid barriers (but not energy barriers) at a rate of 1 foot (30 cm) per round, and you can perceive while phased within a barrier or object, which allows you to peek through walls.
Action to initiate.
You change your phase state for the next minute so that you can't affect or be affected by normal matter or energy. Only mental attacks and special transdimensional energies, devices, or abilities can affect you, but likewise you can't attack, touch, or otherwise affect anything.
Action to initiate.
This ability works like the Phased Attack ability except that your attack also disrupts the foe's vitals, dealing an additional 5 points of damage.
or
You gather disrupting energy in your fingertip and touch a creature. If the target is an NPC or a creature of level 3 or lower, it becomes phased as if it had used the Ghost ability. However, unless it can figure out how to control its movement while being phased, which most creatures have no experience with, it begins to sink through solid matter. If it can't control itself or end the effect, it might be gone for good because when it becomes solid again after ten minutes, it's probably deep in the earth. For each additional level of Effort you apply, you can attempt to affect a target of one level higher.
GM Intrusions: The character is sent phasing into an unexpected dimension. The character becomes lost in a large solid.
