Strength of Spirit is a 7th-level cleric encounter attack power, introduced in Dragon Magazine article Battle Cleric Options, and is a hybrid of the two intentions in the article by both making a target more vulnerable to attacks and by a soft inhibition on making the enemy attack. [Dr400]

It is rated as an excellent choice due to the effect line allowing for a potentially high bonus on the target, and is otherwise considered the highest-damaging power at the current level when using a simple weapon.[Charop cleric]
