|Examine||This crystal will make you temporarily invulnerable.|
The Crystal (invulnerability) is a type of lava crystal that spawns throughout the Fight Kiln minigame after completing waves 1, 13, and 25. It can only be used in this minigame and disappears after leaving. This crystal reduces all classed damage to 0 for 30 seconds, at which point the boost wears off. The damage inflicted by TokHaar-Ket-Dill when it slams the ground is classless and therefore unmitigated by the effects of this crystal. This is a crystal that is often picked up and used, as it can be very useful in dealing with the first few hits on waves that spawn TokHaar-Jad, as well when there are two TokHaar-Jads that are hitting the player on wave 36.
