This ability always takes the form [SUSTAINED HITS X]. Each time an attack made with a [SUSTAINED HITS] weapon results in a critical hit, that attack results in a number of additional hits on the target as denoted by X. Example: An attack made with a [SUSTAINED HITS 2] weapon results in a critical hit. That attack therefore hits the target three times (once from the critical hit, and twice more from the [SUSTAINED HITS 2] ability).
