Memiroa

Memiroa is the final boss from Final Fantasy Crystal Chronicles.

Battle Tactics
Memiroa's attacks all inflict obscene amounts of damage and have area effects. To make matters worse, its health is not listed on the GBA screen at all, which means that you have absolutely no idea how close to death the nightmare is. The strategy for beating Memiroa is thus: destroy the creature's crystal talon in order to access its vulnerable head. This is far from easy, however, due to the previously mentioned extremely powerful attacks: while the talon is intact, Memiroa will use a red laser beam that strikes a single point almost instantly that inflicts massive fire damage on anyone caught within the explosion, and a linear blue laser that freezes anything it touches. It will also slam the ground with one of its claws in order to stun an opponent. Once the talon has been destroyed, it will attack with either a black laser that inflicts serious damage, or a pair of white lasers that can pretty much kill a character in a single hit.

Phoenix Downs help a lot during this fight, and it's recommended that you keep at least one in your command slots at all times. This is especially true in single-player mode, as there's no one to cast Life on you.

In single player mode it is extremely helpful to collect the memory bubbles that will float down from above before the Crystal Talon captures them itself. When you cast a spell Cure for instance on a memory bubble, it will transform into a magicite labeled ????. Each magicite casts a random -aga spell, so it will not be that easy to get the one you want. The spell to go for however is the one that makes you invincible for a short amount of time, recognizable by the blue glow that surrounds your character. Memiroa can do nothing against you while you are under this spell, so it is advised to collect a good amount of the ???? magic, and when his head drops down, quickly go your command slots and set all except for 1 (which should be a Phoenix Down) to ???? and quickly cast them until you get the invincibility spell. Then you just keep attacking, focus attacking, casting spells, whatever your preference is at his head. Rinse and repeat and Memiroa will fall. The amount of memory bubbles one can acquire is tied to the amount of memories they have. Each bubble spawned consumes one memory. Because of this, players visiting from other save files will be unable to acquire their own ???? Magicite, although they can collect them from their allies.
