Damage type(s) and Attack Speed influence combat. The attack style of the weapon in relation to the combat environment is also important. Consider both when choosing weapons to wield.


Boosts and Penalties are both considered "abilities" in general. Many items don't have any special abilities. See the Abilities page for details. Some enemies are immune to certain status conditions - see individual status pages for details.

The Obsidian Crusher is a 5-star bomb.


A peculiar bomb made from the obsidian obelisks found within the realm of the Apocrea. Despite it being a bomb, some are drawn to holding it and 'solving' it as if it were some kind of puzzle.

Charged Attack

Like all bombs, the Obsidian Crusher requires a charge attack in order to be set. Once it is set, it takes about three seconds to detonate. Its blast creates a vortex that will pull in any non-friendly character within range to the center of the blast and large-purple tendrils come out of the vortex causing additional damage and keeping them there for four seconds before exploding again, which inflicts more shadow damage and scatters out its captives during the second explosion.


The following damage values represent the weapon at its completed level, without any UV or bonus from other equipment, and are listed as a range found from the first to last floor of each stratum. The damage is identical to all Mist Bombs.

The initial detonation also deals very low, normal-type damage that appears to carry the strength of a 0* weapon. The detonation damage is presumably only there for utility.
