How does the Frenzy skill work?

[Raygun]

In the alchemy tree, in the trial of grasses branch, the first skill, Frenzy, says that after a enemy counter attacks, time is slowed (if toxicicity is above 0). I haven't noticed this take effect and ive been under the effects of potions (im toxic). Maybe a enemy has never countered me, Im not sure. What counts as a enemy counter attack? Any insight into Frenzy is appreciated.

Its pretty broken at the moment... when it should slow down is when ya keep hitting them and they will eventually hit ya back out of no where. in most of those cases the slow down never comes out or bugs out. i believe it have something to do with normal attacks never being taken as counter attacks, it really needs to be looked over and revamped. my best bet would be to go training with quen "active shield" giving ya health each time they strike ya while trying to parry their attacks when they are about to hit ya. tricky but pays off eventually.

Doxy! is spot on with the video. My curiosity is -- does it require an attack to trigger? Physical attack (fast would be best -- more hits, more trigger effect), Magical? (Igni? Arrd?, though there is no real way to block or parry that). Magic attacks are probably right out.

So. lots of fast attacks to gain most advantage of...
