Act2 merc with 'on striking' weapon

[Ferengi]

While thinking about my favorite annoying monster opponent, I realized that my merc might help the skeletons kill Meph if he had some sort of 'on striking' effect. Since many things have changed in 1.10, I don't know about the merc's Jab attack and such effects. Jab is normally 3 fast attacks, so for one Jab attack, do I get three chances at triggering an effect? Or just one trigger per Jab?

TIA

My guess is 3. If you have any way of making one, try getting a weapon with a high chance to cast Amp. If you hear more than 1 "dey" sound per string of hits(possibly by observing elemental damage "sparks" on contact), it's kicking in per "jab-let" Or try using a chance to cast firebolt on attack weapon.

The Jab sequence that the act 2 guards use has only 2 attack points in it, not 3 as the amazon Jab does. And the CTC can be triggered on both as appropriate the CTC type (on attack or on hitting).
