Concise: If target foe is casting a spell or chant, that skill and all skills of the same attribute are disabled (1...10...12 seconds) and that skill is interrupted.
Interrupting an unlinked or title skill will not disable any additional skills.
The spell or chant cast by target foe will fail at the end of its casting time even if target foe is under effects that prevent interrupts due to the skill disablement.
