I couldn't finish 'em. Looks like this's gonna get complicated.
Misery is a boss in Final Fantasy Dimensions and one of the four Blades of Nil. The party encounters it in the World of Misery through the Dark Gate. Misery is responsible for stealing the dreams and hope of the Dwarves in Castle Falgabard.
Upon the party confronting the entity, Misery reveals its actions have no real meaning or purpose, and that its deeds have no reason whatsoever since it believes life is meaningless as everything is fated to die. The party confronts the monster reasoning that dreams and hope give life meaning and a battle ensues.
Following its defeat, the Warriors of Light and Darkness deduce that what Misery sought in true was to simply do nothing at all. Misery resigns itself to return to the nothingness it was born from.
Misery is a physical attacker and can attack several times per turn. It uses Sweep as a party attack, Fang and Claw for stronger single target attacks. Bite which can inflict Poison and Confusion and occasionally will use Roar to inflict Stun on the party. Nearing death it starts to use Pox which attacks the whole party and inflicts Deprotect reducing defenses. It can also use Chaos Claw which dispels buffs and inflicts a random debuff.
All its attacks inflict nearly 1000-2000 damage and near 1000 with Protect. At this point in the game it has rather high HP than most bosses faced, but is otherwise an unremarkable foe.
Misery is a feeling of great unhappiness, suffering and/or pain.
