“You just walked through a wall."..."Phasers do that sometimes.”
A Phaser is one of the special abilities an elf may manifest as. Phasers have the ability to break down their cells (similar to light leaping) in order to walk through solid objects such as walls and even things such as swords. Some talented Phasers are able to disassemble only parts of themselves like Blur, appearing partly visible and smudged as part of his disguise. The Silver Tower, Gold Tower, and Exile are impenetrable to Phasers.
