Full: If target foe is casting a spell or chant, that skill and all skills of the same attribute are disabled for 1...10 seconds and that skill is interrupted.
Concise: If target foe is casting a spell or chant, that skill and all skills of the same attribute are disabled (1...10 seconds) and that skill is interrupted.
The effect of disabling skills of the same attribute will still take place even if the target's skill did not get interrupted (such as if target is protected by Mantra of Resolve). The disabling will cause the target's skill to fail, bypassing the anti-interruption effect.
As indicated by the literal interpretation of the skill description, interrupting an unlinked skill with Power Block will not disable other unlinked skills, and interrupting a title skill will not disable other skills linked to the same title.
Anomaly! The concise description erroneously states that the disable is an "interruption effect," but it will take place regardless.
