Voidscar Arena

Pack A (Enthralled Shaman, Savage Shredclaw, Kilivore Screamer) was engaged at 10:32. The Watchful Harrower flies in from about 50 yards ten seconds later; its first action at 10:42 was a swing on Blood DK, which is where it belongs. Screamer dead 11:07, Shaman and Shredclaw 11:16. That left the Harrower at 45%; it lost 9% in the 17 seconds before the group moved on.

At 11:32 Resto Druid pressed Stampeding Roar, Blood DK pressed Death Grip, and pack B (Brutal Overseer, a second Enthralled Shaman, Dominated Brawler) was in the fight by 11:36, with the Harrower still up at 38%. The Harrower started a Sky Strike at 11:37 and the Overseer started Brutal Slams at 11:42.3. Sky Strike landed at 11:42.5 for 1.41M across Ele Shaman, Blood DK, Resto Druid and Arcane Mage; the shield went up at 11:44.3.

  11:50  Ele Shaman    slams 907k + Sky Strike 505k over 7.6 s
  11:54  Hyporock  slams 973k + Void Beam 737k over 13.6 s   (Divine Protection pressed at 11:44)
  12:05  Resto Druid  slams 2.98M over 13.5 s; the 3.1M healed in that window was his own Regrowth, Swiftmend and Wild Growth, 14k from anyone else
  12:06  Arcane Mage    slams 905k + Searing Magma 393k over 4.3 s (Prismatic Barrier up)

The shield broke at 12:06.6, 22.3 seconds after it went up, with only Blood DK standing. Ele Shaman was back by 12:21 and died again to Void Beam and Searing Magma. When the log ends at 12:37 the Harrower is at 17% and nothing in pack B has died.

The tooltip is plain: the Overseer shields himself and slams the ground every 1.5 seconds for 30 seconds, hitting everyone at any range, each slam 10% harder than the last. No positioning answer, no dispel; the shield is the off switch. It is exactly 4,032,014 at +15 in both of today's keys and ate 0.7% of the party's damage all key. The cost was never the shield; it was the 10.0M of slams (29% of everything the pull did) that landed while it stood.

During the 22.3 seconds:

  into the shield              4.03M
  Dominated Brawler            4.87M
  Enthralled Shaman            4.01M
  Watchful Harrower            3.87M

  Arcane Mage      1.77M into the shield, 5.59M elsewhere
  Hyporock    0.95M            3.71M
  Blood DK     0.66M            2.26M
  Ele Shaman      0.34M            1.06M

In the first five seconds after the shield appeared the party put 1.14M into it and 3.48M into other targets. Arcane Mage put the most into it, and still three-quarters of his damage went elsewhere. Nobody was slacking; everyone was cleaving a stacked pack and the Brawler and Shaman absorbed the cleave. The fix is a target swap, not more damage.

For scale, the 09-15 +15 and 09-13 +14 clears each broke two of these shields (8.05M and 7.33M absorbed, i.e. 4.03M and 3.66M apiece, the usual 1.10x per key level) and Brutal Slams did not reach the party-wide damage list on either page.

31.1M health, against 20.2M for the Overseer and 11-14M for everything else in the pull, so it takes the longest to kill and it was hit last both times today. Sky Strike is a five-second cast that charges someone and hits everyone within 10 yards; the tooltip says the damage is shared among those hit, and the group stacked for it correctly every time (four or five of five caught), taking 260-540k each, roughly half a DPS's 0.86M health bar. Three casts did 4.6M, 13% of the pull. Void Beam is a two-second cast then a four-second puddle: 2.7M. And its melee is the hardest in the pull: 3.2M on Blood DK, more than every other mob's swings on him combined.

Sky Strike and Void Beam are Nature and Shadow, so a Blood DK's Anti-Magic Shell and Zone answer both. Blood DK pressed Anti-Magic Shell once, at 12:10, after the slams had ended, and Icebound Fortitude never. The slams themselves are Physical and neither helps with them.

The Harrower alive beside the Overseer is what made this pull different from the 09-15 clear: its Sky Strike arrived in the same second as the shield, and it took 3.87M of damage that belonged on the shield.

Resto Druid at 1:07 in the entrance pack: a Shadowbolt Volley for 1.12M, a four-second cast that is the one thing in this dungeon worth a million per landing (2 of 7 leaked this key), plus Savage Leap and Lava Bolt. Hyporock's Lay on Hands at 0:58 bought nine seconds. Lava Bolt was the group's one leak: 14 of 30 got through, against 89% of everything else stopped.

Ele Shaman at 9:05 on Taz'Rah: Umbral Rupture for 806k, a shade's ground effect that did zero damage on the 09-13 clear because nobody stood in it, plus 946k of Nether Dash. That is a position. None of Ele Shaman's three deaths had a defensive pressed in the window; Astral Shift went three times all key.

On the grades: an abandoned key, so every axis describes 12.6 minutes and a wipe. Hyporock's mechanics 79 (Forked Lightning x11, peers 0) is the grader's cohort-of-one artifact: he is the only melee DPS and the ranged took it 7 and 7 times; there is nothing there. Resto Druid's throughput 71 means he covered 75% of the healing the party needed on a key that asked 161k per second, past the 95th percentile of every key this scale was cut on; read it as a floor, and note 18.4M healed in this one pull. Blood DK's mitigation 45 is real: 53% uptime of the 76% a Blood DK can hold, half the worst windows covered.
