PS5. Not sure if universal.
On Barbarian, if you imprint the Raid Leader aspect and use any of your shouts (only shouts, other abilities don’t trigger the issue), you repeatedly lose chunks of your health. It seems to tick for the duration of what is supposed to be the heal and has nearly killed me on numerous occasions.
I was wondering what was happening and I ultimately ended up removing the armor piece with the aspect and the self damage stopped. Putting it back on resumed the self damage whenever a shout was used.
