Betrayal
Psion Attack 3
You weaken your foe's sense of self, and force it to betray a comrade.
Ranged 10

Attack: Intelligence vs. Will
Hit: You slide the target 1 square adjacent to an enemy. The target then makes a melee basic attack as a free action against that enemy, with a bonus to the attack roll equal to your Charisma modifier.
Augment 1
Hit: As above, and the target gains a bonus to the damage roll equal to your charisma modifier.
Augment 2
Hit: As above, but you slide the target a number of squares equal to your Charisma modifier to a square adjacent to an enemy, makes the attack with a bonus to the attack and damage rolls equal to your charisma modifier, and is also dazed until the end of your next turn.
Betrayal is a third-level psion augmentable attack power, designed to force enemies to attack others.[PH3:85]
It is rated as a good choice. While the base at-will relies on a strong damage for an attack, the second augment proves to provide good battlefield control against single targets, especially at higher levels (where it may become an excellent choice). [Charop Psion]
