Oathkeeper's Aegis of Menhir inconsistency

First of all, hi everybody it’s been a couple of years since I last came here :slight_smile:

I just bought the Forgotten Gods expansion and I’m trying an Aegis build but I’m having a bit of an issue with this skill.

I try and group enemies together before using the skill but sometimes it just hits the first enemy and then flies away to hit the farthest one from the group.
This puts the attack too far to reach any other enemy and it comes back to me.

Is there a trick to using this skill or understand which enemies it’s going to aim for?
