Затемнение 6 позволяет менять свою ауру, а вот изменения чужой ауры не нашел.
Малкавианская комба работает только на свою ауру, а не на чужие
Комба Изменчивости с Прорицанием подходит, вроде бы, но у нее очень уж краткосрочный эффект
Нет ли у тауматургии/темной тауматургии ритуалов по изменению ауры?
Ну есть вот такой ритуал, чертовски геморный и кратковременный :
Cloak of Blood
Many Licks would give much for a way to conceal
the black stains left on their auras by diablerie . Fortunately,
there is a ritual to accomplish this effect : the
Cloak of Blood . It is only a Level One ritual, easily
performed by a neonate, but the ingredients and effort
required make it very difficult . Before the ritual's casting,
the Diabolist must fast for seven nights . During this
time the Diabolist must not drink any blood, for the
Diabolist's heart must be cleansed of tainted vitae . After
the seventh night, the Diabolist inscribes a rune on her
chest, in her own blood (the Diabolist or another may
perform the actual ritual) .
Then the Diabolist must take blood from an innocent
mortal. The blood must be freely given and not
taken through violence, force or coercion . Deception is
the usual method. This can be very difficult, for the
Diabolist is extremely low on blood at this point and is
likely to go into a frenzy, drinking her fill by force rather
than guile .
Once the vampire drinks the blood, the black lines
in the Diabolist's aura are hidden for a number of nights
equal to the Blood Points taken from the innocent
mortal. If any Blood Points are spent prematurely (to
heal or to enhance Attributes), reduce the effect's
duration by the number of Blood Points spent . If the
Diabolist drinks from another source, the spell's effect is
diminished . No longer are the black blotches invisible,
although the number of Auspex successes required to
detect the marks is still raised by one per remaining
Blood Point .
Needless to say, if diablerie is committed after the
ritual is cast, all benefits are lost and the black lines are
more visible than ever . The use of this ritual itself often
causes Humanity loss, as the deception and possible
death of an innocent are always involved .
