Greetings forum.

So, like it says in the title, I'm not quite sure what the skill does. I'm trying to learn how to tank, and I've been splitting up leveling my DRK between the daily roulettes and PotD, but this is just bothering me. Like, I've read the tooltip time and time again, but whenever I use it in actual battle, whether it be solo FATES, or the roulettes, I never see any damage from it.

I get that it's an AoE. But, does the whole "...a potency of 75 to any enemies who enter." mean that they have to be drawn into the AoE first for it to trigger, or can they be in the field as it goes off? Also since it has a duration, does that mean it's a DoT as well, or does it just do that damage once, then just sits then until the enemy is brought out and back in?

Any help would be appreciated.
