Long story short:
We got to Lupicus. Got him down into the second phase.
Three people died pretty soon, me and our warrior kept up for longer. We both kept dealing damage with occassional hits at long range.
Lupicus focused on the warrior, got him downed. I was still being shot at with the green orb, i still kept dealing my silly staff ele damage. Couldn’t really revive the warrior and didn’t want to risk us both dying, so i just focused on keeping myself alive and keeping Lupicus from resetting until the previous trio got back, as one of them was really close already.

The best part:
So Lupicus finished the warrior off and then decided to ignore me, to just reset back to his spawnpoint and go back to full health. As you can see in the first picture, i am still seen as in fight, as i kept hitting the boss when he was killing the warrior.

I never left the room.
I haven’t broken aggro in any way i know of.
I used the elite a while earlier but then only used the leap skill (3, Pounce) as it serves as a third so-so dodge and i don’t really have anything better to slot there as a norn ele – for that particular fight, with phase 2 in mind.

We had the same problem a few weeks ago when attempting Arah for the first time.
We got to Lupicus, got him down to phase 3. I was downed in one side of the room, not in a corner and still insde, but far from others; was using Bandage to get up on my own. The boss got one of the other three party members down and the other two rushed to revive him, only to get downed by Lupicus together.
Before they got downed, i managed to get back on my feet, and was still seen by the game as ‘in fight’. On the other side of the room, we had 3 downed players – not dead, downed – and Lupicus right at them.
And then he decided to reset. Completely.

I revived the downed ones, but it made us ragequit that night.

Lupis killed it’s target, it was trying to get new target, you were out of his target range, Ai says no target left, reset.

So his target range should be of at least 1200, as i was still hitting him when he decided to ignore me.
