Attack timeline
4 recorded actions for this boss, in data order. Values are stored base client parameters.
1 Delayed blast
A marked blast that detonates after a 1-3.4 s warning, on a 6-16 s cycle where an interval is listed. The data does not record the blast radius, so the edge is not a safe place to stand.
- Interval
- 7 s
- Warning
- 2.6 s
How to handle: Leave the marked area as soon as the warning appears and keep walking until it detonates. Do not stop at the border: without a recorded radius, assume the whole mark is hot.
Inferred from game data — not yet verified in game2 Scattered circles
In-game text“Kurinnaxx calls down meteors!”
Several ground circles land at once; the game warns "the boss calls down meteors!". The data records 3-8 circles, a 1.4-2.8 s warning and a 7-13 s cycle.
- Interval
- 9 s
- Warning
- 1.4 s
How to handle: Find the largest gap before the warning ends and commit to it; do not weave between circles at the last moment. With eight circles, move early rather than react.
3 Charge
In-game text“Kurinnaxx squeals and charges!”
The boss charges; the game announces it with "the boss squeals and charges!". The data shows a 7-11 s interval on the bosses that list one and no warning time.
- Interval
- 9 s
How to handle: Do not backpedal in a straight line: sidestep as the charge commits, then punish the recovery. The boss turning toward you is the cue.
4 Summon
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
- 14 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.

Suggested build focus
Build tips recorded for this boss's attack types.
- A movement ability is more reliable than last-second sidesteps, especially on the 1 s warnings. Inferred from game data — not yet verified in game
- Wider area coverage helps, but the main need is a clear exit lane and a movement speed boost.
- Save a dash for the commit; the charge is easier to dodge sideways than to outrun.
- Area damage pays for itself here: one clear per wave beats single-target cleanup.
