A question about Leprechauns' magic attack

Did you do anything specific to get them to stun you? Cause I havent been able to get them to stun me/seen them stun others.

Just curious, but was this implemented in the SC along with downgraded eggs and bigfoot?

It was there since the start. A few of us claimed getting stunned on the second day or so and no one believed us.

The leprechaun on the bottom left of Forgotten Path stunned me twice and I never noticed the animation for it, although I was fighting several Elder Wraith at the time. I've also seen the leprechaun at the top of Forgotten Path do the stun animation but it oddly didn't stun me.

... and I still have no idea how to provoke it.
