Demon Wall (Final Fantasy IV 2D)

The Demon Wall, also known as the EvilWall, is a boss from Final Fantasy IV. It is the last wall of defense in the Sealed Cave after getting the last Dark Crystal.

Battle
This battle must be won quickly, as the Demon Wall will constantly close in on the party, and when it gets close enough, will start to use an Instant Death attack called Crush.

Strategy
The player should immediately inflict Slow using either Spider's Silk or the Slow spell. Rosa should cast Berserk on Cecil, Kain, and possibly Edge if the player chooses not to use his Throw command. Rosa can then heal, or revive them with Raise if the Demon Wall uses its instant death attack.

Assuming the player has been to the Sylph Cave, they could equip Cecil or Kain with the Avenger sword. Not only does it put them in Auto-Berserk, saving Rosa a turn and increasing damage output, it also increases their Strength, Agility and Stamina by 10.

DS/Smartphone Version
This battle will be very difficult, as the wall has 40,000 HP (in all other versions, it only has 28,000 HP). Giving Rosa the Dualcast augment before the battle makes it slightly easier. Rydia should always use her best summons, and Kain, Cecil, and Edge always attack on their turns. When it is Rosa's turn, she should Dualcast Slow on the Demon Wall and Haste on herself, then cast Haste on everyone else. Afterward, Rosa should cast Berserk on Cecil, Kain and Edge. Rydia should keep summoning.
