Doom of Mokhaiotl: car attack is a mechanic topic that Gnomonkey covers in 5 videos between 2025-07-23 and 2025-08-22. This article is a stub: his statements are grouped by type, repeated ones merged.

Contents

Methods

  • From cave 5 the Doom of Mokhaiotl turns into a car after the shield breaks: it places an eyeball icon on the ground and drives toward it to run you over, doing this two times before returning to the normal fight.1
  • On Doom of Mokhaiotl cave 6 the car does two orbs at you (two prayers) on each dash and then a slam, so you must get behind rocks for cover.2
  • Gnomonkey pushes the Doom of Mokhaiotl down toward 75% and uses a Zaryte crossbow spec right before the shield phase, because the damage the Zaryte crossbow does before you send the boss into the shield phase carries into the car phase, giving a very high chance of killing it before the orb phase.3
  • Car phase on Doom of Mokhaiotl begins after shield phase from delve 5; you should arrive with as much spec energy as possible and Death Charge from grubs, because the phase is 100% accurate.4

Stats and numbers

  • The Doom of Mokhaiotl slam visually appears to reach only part of the room, but Gnomonkey says that is a bug and the slam hits the whole room, so running far away does not work.5
  • When the Doom of Mokhaiotl is in car mode you are 100% accurate and cannot miss, similar to a phase of Tormented Demons, and this can be exploited with many weapons.6
  • The shield phase is also 100% accurate, like the car phase.7
  • When the Zaryte crossbow spec lands right before the shield phase, the Doom of Mokhaiotl stops attacking you because it moves into the shield phase, which protects you and increases your odds of getting through the orb phase.8
  • With double Death Charge and a Lightbearer stall in the shield phase you can get a second Zaryte crossbow spec before the car phase, which Gnomonkey says makes the odds of an orb phase sub 5% (his example had the boss at 416 HP going into the car phase).9
  • In car phase the boss spawns an eyeball four tiles behind you in line with the boss's centre and then dashes toward it; on delve 5 it hits about 10 if you are in the way, on delve 8 about 40 and it dashes almost instantly.10
  • Car phase has only two dashes on delve 5, three dashes with shockwaves on delve 6, and the boss is at about 145 health after it on Gnomonkey's delve 5 run.11
  • The car phase is introduced on delve 5 with no shockwaves and only two dashes, so it is not yet the full boss fight.12

Tips

  • The Doom of Mokhaiotl car's AoE destroys nearby rocks, so you must be deliberate about where you drive it to avoid running out of cover; if there are none left you just take the 40 damage slam.2
  • The first Doom of Mokhaiotl car phase is always safe and only does two dashes, so you can safely get into range at that point.13
  • Gnomonkey tries to open with a Zaryte crossbow spec as soon as the Doom of Mokhaiotl shield disappears and it turns into a car, which can kill the boss before any stalagmites appear.14
  • Your damage output immediately after the car spawns decides whether you get past the orb phase, because if you do not do enough damage the boss leaves car phase, starts spawning earthen nodes and you have to deal with the orb.15
  • You could take around 80 damage per Doom of Mokhaiotl car phase if you mess up the shockwave or get hit by the car.16
  • The Doom of Mokhaiotl is hit around 85% or below after a big Twisted bow hit; the Scorching bow maxes a lot lower so you can get the boss lower, maybe below about 81%, without accidentally sending the shield phase before the rocks are down.17
  • You cannot attack the boss while it is transforming into the car, so use that time to kill nearby grubs, and you are also immune to all damage for about three ticks, so you can run through acid.4
  • To maximise the time the boss is dashing in car phase, by dragging it to a corner or side, to get more blowpipe and Dragon knife damage, especially if not using a Twisted bow.18
  • On a budget setup you must be right next to the boss with the blowpipe in car phase to avoid orb phases.19

Gnomonkey's opinion

  • Gnomonkey says the Doom of Mokhaiotl car attack may be the best attack in the whole game.20
  • Gnomonkey says the car phase is one of the best mechanics of any boss, praising its mechanical depth, risk and reward, prep in the earlier phase, and 100% accuracy that lets unique weapons and specs shine.21
