Heroic Slugger

A rare spawns in the zone every 20 minutes with a red yell indicating it in the chat: "Scouts have reported a dangerous enemy has been spotted. Take it out!"

The rares spawn in 3 different groups, with each following the same rotation of rare spawns:

!Group spawned is RANDOM (e.g. 1>2>1>3)!

1: Indomitable Mk XII > Warbringer Thal'kuur > Warp Agent Xi'grivr (These ones spawned in this exact order)

2: Auredar > Broxion > Swalewing Matriarch

3: Slaipaan > Interminable Uarn > Lomelith

I will update the comment as I learn more about the spawns, let me know if I've missed anything or if something's wrong!

Val rares work the same as Naigtal rares. Roughly 20 minutes between spawns.

They spawn in 3 separate groups. Each group can spawn at random, but will not repeat the same group immediately. Once a group spawns, it will go in the exact order of the group.

Group 1. Xirah, Sleet-Rune, Atomas
Group 2. Krilkan, Glacial Broodmother, Mercilus
Group 3. The Horror Below, Opprimius, Nelgothar

There is also the Shadowguard destroyer, but it didn't seem to be in the rotation, and I somehow have credit for killing it at some point. Maybe it's the Val version of that stupid bat in Naigtai.
