Syntax: cast 'tamper senses'
While affected by this spell, psionicists are able to tamper with the senses
of those around them, temporarily blocking their sight and hearing, allowing
them to pass through the area unseen. The chance to go undetected is
increased by how skilled the psionicist is in sense tampering and on the
psionicist's dexterity. The chance is decreased by the intelligence of the
whoever is attempting to detect the psionicist. This spell can only be cast
on oneself. To remove the effect, type 'visible'.
