Career abilities that grant bonuses to nearby allies trigger friendly fire voice lines

The two abilities I know are guilty of this, is Witch Hunter “Animosity”

and Mercenary “Morale Boost”

It might be related to the knock back effect these two abilities have, as I’ve noticed they destroy objects like bottles around the keep

These abilities does in fact, trigger Ironbreaker Bardin’s passive gromril armour.

Apparently some abilities deal 1 damage to teammates hence the friendly fire voice lines and green crosshair. So watch out not to kill yourself or others while having 1hp and throwing a smoke bomb and such.

That would make sense, and yes indeed that means the smoke bomb for Bardin/ranger too does this.
