Boss yell“Well done, my minions. The mortals' courage begins to wane! Now let's see how they contend with the true Lord of Blackrock Spire!”
Attack timeline
5 recorded actions for this boss, in data order. Values are stored base client parameters.
1 Projectile volley
In-game text“Nefarian hurls axes across the field!”
The boss throws a volley across the field; the game warns "the boss hurls axes across the field!". The data records 5-9 projectiles every 4.5-6 s.
- Interval
- 5 s
How to handle: Strafe between the gaps instead of backing away, and change direction only after a projectile passes. With a 4.5 s cycle there is no safe standing window.
2 Frontal cone
A cone attack in front of the boss, telegraphed for 0.9-2 s and repeated every 5-10 s where an interval is listed. The data does not give the cone's angle or range.
- Interval
- 10 s
- Warning
- 2 s
How to handle: Use the warning to step through the boss's side or behind it; walking straight back keeps you in the cone longer. Re-enter after the telegraph resolves.
Inferred from game data — not yet verified in game3 Action sequence
A scripted combo: the boss performs two or three actions, with each follow-up landing a fixed gap (0.1-1.8 s) after the previous one. The parent entry is a container; the child steps carry the actions.
- Interval
- 11 s
- Gap between steps
- 1.6 s
How to handle: Watch the first action, not the parent timer: the follow-up arrives 0.1-1.8 s later, so pre-move during the first cast. Short gaps under 0.5 s leave no room to react twice.
Inferred from game data — not yet verified in game- 1Circle around the boss Boss-centered circle
A hazard centred on the boss: the game warns "Lava wells up around the boss!" or "the boss pounds the ground!", then the marked area around it resolves. The data adds a 1.3 s warning and a 7-12 s cycle.
How to handle: When the warning appears, step out of the area around the boss and wait for the hit before re-entering melee. A 7 s cycle leaves little time to finish a long cast.
- 2Ring Ring (donut)
A ring-shaped hit with a 1.4-2.6 s warning, repeated every 9-10 s where an interval is listed. The middle is not part of the ring, so the shape has a hole rather than a filled centre.
How to handle: Move into the hole or out past the outer edge, whichever is closer, and commit before the warning ends. Do not stand on the ring itself; the data does not give its width.

4 Alternating lanes
Lanes light up in alternation, with a 2 s warning and a 15-16 s cycle. The data does not give the number of lanes or the order in which they fire.
- Interval
- 16 s
- Warning
- 2 s
How to handle: Move into the lane that just went dark, not the one that is lighting up. With a 2 s warning, start moving before the current lane finishes.

Add waveIn-game text“Minions, to me!”
The boss calls in a wave of adds; the game announces it with "Minions, to me!" or "A pack hunts you!". The data records 4-14 adds on a 10-16 s cycle.
- Interval
- 11 s
How to handle: Clear the pack before the next summon lands; at 14 adds a single-target build falls behind. Keep moving so the new adds do not surround you while you finish the last wave.
Phase changes
Below 60% health · one trigger
- Circle grid
A grid of circles covers the ground, telegraphed for 2 s and repeated every 12-15 s where an interval is listed. The data does not give the grid size or how many cells are safe.
How to handle: Move to an unmarked cell during the 2 s warning and stay there until the grid resolves. Do not cut diagonally through marked cells to reach a better spot.

How to handle: Clear the pack before the next summon lands; at 14 adds a single-target build falls behind. Keep moving so the new adds do not surround you while you finish the last wave.
How to fight it
Up to three actions, taken from the timing data: shortest warning, shortest interval, then the first new phase action.
- 1Shortest warning (1.3 s) Circle around the boss
When the warning appears, step out of the area around the boss and wait for the hit before re-entering melee. A 7 s cycle leaves little time to finish a long cast.
- 2Most frequent (every 5 s) Projectile volley
Strafe between the gaps instead of backing away, and change direction only after a projectile passes. With a 4.5 s cycle there is no safe standing window.
- 3At 60% health Circle grid
Move to an unmarked cell during the 2 s warning and stay there until the grid resolves. Do not cut diagonally through marked cells to reach a better spot.

Suggested build focus
Build tips recorded for this boss's attack types.
- A movement-speed item or dash makes the gap between volleys much safer.
- Melee builds should circle toward the flank during the warning; ranged builds can strafe out of the wedge. Inferred from game data — not yet verified in game
- Instant movement is worth more than a long defensive cooldown here; the combo punishes standing still between steps. Inferred from game data — not yet verified in game
- Melee builds need a movement plan here; ranged builds can keep uptime from outside the circle.
