Disaster Shadows are special Shadows that can be encountered in Palaces and Mementos, and are signified by a purple-blue aura around them. These Shadows do not attack during their turn, but can otherwise retaliate once attacked and not destroyed during a party member's turn. The attack does not have to hit for the Disaster Shadow to become enraged, the only requirement is for them to be targeted with an attack (This includes multi-target skills such as ma- family magic attacks). Disaster Shadows can be attacked without fear of retaliation if the attack also knocks them down, or inflicts them with an ailment that prevents them from acting, such as Sleep or Despair.
Once destroyed, the Disaster Shadow will explode and heavily damage nearby enemies while dropping a valuable item, such as a rare consumable or powerful Incense for the Velvet Room. This explosion is Almighty, and the damage is influenced by how powerful the lethal attack was, so it is recommended to use a strong skill to defeat them. This is especially effective in conjunction with Baton Pass, and can be strong enough to end a fight by itself, so prioritize attacking these Shadows when they show up. However, if they are killed by Despair, a reflected attack, or an instakill effect such as Hamaon, it will count as defeating the Shadow normally, with no explosion at all. Defeating the Shadow without triggering the explosion still merits their dropped item.
Any parameters such as moveset, stats, and elemental affinities on a Disaster Shadow are identical to their normal Shadow counterparts; the only thing different is their behavior, which differs radically from any normal enemy.
