Crabs (Chambers of Xeric) is a mechanic topic that Gnomonkey covers in 2 videos between 2024-11-08 and 2025-05-01. This article is a stub: his statements are grouped by type, repeated ones merged.
Methods
- In solo CM Crabs there are four crabs; they load as soon as you cross the loading line and wander around, so Gnomonkey loads the room without entering and then runs in with mage gear.1
- Gnomonkey clicks roughly the middle crab first, since a crab near the crystal can wander behind it and get blocked, then lures it toward himself and shoots it with the Twisted bow before switching back to mage.2
- The Crabs sequence he teaches is: run in, mage the first crab, step, Twisted bow the crab, step, mage, step down, mage, step, smash a crab in place, mage, smash, mage, then bounce the light off three crabs into the yellow crystal.3
- Gnomonkey lures the middle crab with a staff from a marked tile near the top right of the crystal, then shoots it with the Bofa so it bounces into the pink crystal; there is a plugin that shows which style each crystal needs.4
- Gnomonkey does the ranged crystal first, then tags two more crabs, hammers them in place, casts at both, catches the mage crystal, and bounces a crab into the white crystal, which takes no colour.5
Tips
- To stop a fourth crab lining up with another crab and wandering randomly (which ruins the light bounce), Gnomonkey steps so the crabs sit in an arc around him; he says lines of crabs cause problems.6
- After bouncing the light into the last crystals, walk (not run) the last crab slowly with unleash, because running makes the crab wander and puts the crystal in the wrong spot.7
- A wasteful option Gnomonkey mentions is spamming Sanguinesti staff on the crabs every tick to heal.8
- Gnomonkey tanks the crab orb to save time, though this is optional.9
- Crabs only stay in place for 50 game ticks after a hammer, so if something does not bounce in correctly, re-hammer the crabs.10
Gnomonkey's opinion
- Gnomonkey says Crabs is harder than people give it credit for, and that a two-minute Crabs while learning is normal.7
- Gnomonkey says people call crabs an easy room but it is genuinely difficult.9
