"Gain a Blitz Charge on Critical Strike"

How does this work?

In my test with multistrike and ancestral call support sometimes one attack on a pack give me like 5-8 charges or even more depend on pack size.

According to wiki multistrike only proc on crit effect once with all three attacks so i think its ancestral call make one attack gives many charges?

Have anyone tested this too?

Multi strike only applies 1 hit per enemy. Since a pack has several enemies, you get up to an equal number of crit applications. This sounds to be working as intended.
