Hide in Shadows

You jump into a target’s shadow. If you were hidden before using this ability, you remain hidden inside the shadow. Else, the target or any other enemy may attack the shadow as if they were attacking you. If you take damage, you are forced out. While you’re inside the shadow, you travel with the target when it moves, including if it teleports, but cannot take actions other than exiting it.

You may exit the shadow willingly for 0 RP. When you exit it, if you were hidden, your next basic attack that turn against the target whose shadow you were hiding in gains Full Pierce.
