Air acolytes of some potency realize it is possible to read the minds of others, but a few shugenja have looked at this as only the beginning of what can be done with Air. Through extremely advanced and powerful invocations of the Air kami, it is possible for a shugenja to not only read the surface thoughts of another but to transit his own thoughts into the mind of that person. This is considered a highly questionable act, and the Phoenix Clan considers this spell to border on blasphemy. However, the immense advantages that can be gained from such total manipulation of another means the spell continues to circulate covertly through the Empire.
In order for this prayer to succeed, the caster must know the name of the target and must be able to see him or her clearly. Without the visual connection, the thoughts of the target will be too garbled to be decipherable, resulting only in a painful headache to both caster and target. If the name which the caster knows is false (e.g. the target is using an alias) the Spellcasting Roll suffers a +10 TN penalty as the false name confuses the spirits. Furthermore, in order to successfully impose his thoughts on the target's mind, the caster must succeed in an Contested Air Roll against the target; failure means contact is broken and both sides suffer a severe headache as above. However, if the Air roll is successful, the target will be unaware of the mental contact and for the duration of the spell will believe the thoughts springing into his mind are entirely his own. The caster must maintain partial concentration for the duration of the spell - if this is disrupted, the spell ends immediately.
A peculiar side effect of this spell is that for an hour after it ends, the caster and target will find it difficult to lie convincingly to each other, inflicting a +10 TN penalty to any Sincerity (Deceit) rolls they make against each other.
