Stories from Beyond the Stars: A Viper Binder learns to listen more closely to the haunting whispers and the cryptic messages given by the vestiges he hosts, though he foregoes learning to hide their signs as he does so. Over time, he pieces these into great legends and stories which hide valuable information regarding various topics, and starting at 2nd level, he can call upon this information much as a Bard would. This functions exactly as Bardic Knowledge, except that the Viper Binder adds Cha modifier in place of Int, and if he has made a good pact that day with all of his vestiges, he gains a +2 bonus. This replaces the Suppress Sign ability.
Council of Minds: At 4th level, while other Binders learn to better control the vestiges within them or the power they grant, a Viper Binder is already opening their minds to even greater influences in exchange for otherworldly insights. If he makes a good pact with a vestige, he may choose to still allow it to exert it's influence over him, and he gains a +1 bonus on attack rolls, saves, and checks for each such vestige. After this decision is made, however, if he then goes against that influence, this bonus is replaced with the normal -1 penalty. This takes the place of the bonus feat most Binders receive at 4th level.
Living Memories: A Viper Binder can share the memories and experiences of the vestiges that influence him and can even make his enemies relive the most horrible sufferings and mind breaking sights of those alien entities. Starting at 6th level, the Viper Binder can call these memories up once per encounter for each vestige who influences him. This replaces the soul guardian class feature and all of it's improvements.
At 6th level, these memories manifest as the spell
cause fear, except they may affect any creature with no more HD than half again the Viper Binder's level (9 HD at level 6, for example).
At 9th level, the Viper Binder can consume two uses of Living Memories to instead cause the horrible nightmares of the vestige to create a
crushing despair affect.
By spending two uses of Living Memories, the Viper Binder can, at 13th level, cause the memories to manifest as a
hallucinatory terrain, with the addition that each round the illusion automatically casts
confusion on anyone within it's area that fails to disbelief it's existence.
At 19th level, he can, by spending three uses of Living Memories, drive the most horrifying and alien sights experienced by the vestiges into the minds of his enemies. This acts a
weird, except that it does Wis damage instead of Str, and all targets, regardless of disbelieving the illusion, are also affected by
insanity from the terrible images they see.
