@Azel I think your spell selection is kinda iffy. That's a ton of Blood Wishing for relatively little effect.
Instead, have Viserys cast Ancestral Awakening to learn Cultural Adaptation and Heroism. He can then Blood Wish a Harmonic Chorus spell on himself to increase his caster level by +2 and an Arcane Concordance spell so that he can Extend all of his spells. While so affected, he casts Nine Lives, Cultural Adaptation, Heroism, Air of Nobility, and
Grand Destiny(using Greater Shadow Enchantment) on each of them.
In addition to the greater understanding of their marks from Cultural Adaptation, they will each benefit from a +2 Morale bonus to Attacks, Saves, and Skill checks, +10 Circumstance bonus to Diplomacy, Intimidate, and Sense Motive, and they will each have four separate charges which can be used to apply a +4 Competence bonus to any Attack, Save, or Skill check. And since they're Extended and Viserys' caster level is temporarily at 20, each of the spells will last 400 minutes.
In addition, have Tyene cast Wind Walk, Neutralize Poison, and Nondetection on each of them. She can also cast Fire Seeds on one acorn for each of them so that they each have a 15d6 Fire damage ace in the hole in case of an emergency.
EDIT: Might as well have him cast Comprehend Languages on them, too, while he's at it.
