Who makes these things!?
Demonolith uses two basic attacks. Its normal attack is not terribly strong but may cause the Curse and Zombie statuses. Its Breath attack will Petrify all party members. Its meanest trick is Pharaoh's Curse that it will cast as a counter attack, inflicting Darkness, Silence, Poison and Curse. Pharaoh's Curse can be avoided if the Demonolith is afflicted with Silence.
When encountered in the Omega Ruins, it will have Initiative.
Stoneproof armor protects the party against its breath attack. In the Omega Ruins the party should always have at least one character equipped with a weapon that has First Strike to avoid being ambushed. Inside Sin, this is not an issue.
A weapon with Silencestrike or Wakka's Silence Buster attack can be used, as Silence will prevent Pharaoh's Curse. Another option is to use Threaten to stop Demonolith from acting. They can be slowed down with Slow as well. Using Armor Break or piercing weapons will be useful when in Silence status.
Its name is a portmanteau of "demon" and "monolith".
demon is "an evil spirit or devil, especially one thought to possess a person or act as a tormentor in hell."A
monolith is a geological feature consisting of a single massive stone or rock, such as some mountains, or a single large piece of rock placed as, or within, a monument or building. Erosion usually exposes the geological formations. In architecture, the term has overlap with megalith, normally used for prehistory, and may be used in the contexts of rock-cut architecture that remains attached to solid rock, as in monolithic church, or for exceptionally large stones, such as obelisks, statues, monolithic columns or large architraves, that may have been moved a considerable distance after quarrying. It may also be used of large glacial erratics moved by natural forces.A
The word derives, via the Latin monolithus, from the Ancient Greek word μονόλιθος (monolithos), from μόνος ("one" or "single") and λίθος ("stone").
