Notes and Strategies: Milleuda spawns with one Knight and one Black Mage. If you defeat the Knight, a Time Mage spawns; if you defeat the Black Mage, a second Black Mage spawns. You only need to defeat Milleuda to win.

In Default phase (>70% HP), Milleuda uses her weak Attack on her 1st and 2nd turns. In Weak phase (70%-40% HP) and again in Very Weak phase (<40% HP), Milleuda uses her AOE Ultimate Weapon Break on her 1st turn and every 5th turn thereafter. The initial Black Mage uses its weak Thundaga on its 1st and 2nd turns; both Black Mages use AOE Blizzaga on their 8th turn and every 8th turn thereafter. The Knight uses Attack on its 1st turn, Armor Break on its 2nd turn and every 7th turn thereafter, and uses Throw Stone every 6th turn after last using it. The Time Mage uses Haste on its 1st turn and every 7th turn thereafter.

The Black Mages here can actually put out a lot of damage if you neglect your magical defenses, so try to fit in at least a Shellga. Milleuda can strip your Shout/Ramza BSB2/Onion Ninja USB Attack buff from you with Ultimate Weapon Break, so it may be a better idea to rely on either a mage team or a hybrid attack buff like Onion BSB. Watch out for Milleuda's Counter Attack before you get Protectga/Wall up, it's extremely damaging with no mitigation.

Boss: 滅 Mateus

Medal Conditions: Reduce Mateus's magic. Reduce Mateus's attack. Reduce Mateus's defense.

Notes and Strategies: In Default phase (>70% HP), Mateus uses Attack on its 1st and 2nd turns, and Southern Cross on its 3rd turn. In Weak phase (70%-40% HP), Mateus uses Slowga on its 1st turn and Graviga on its 2nd turn. In Very Weak phase (<40% HP), Mateus uses Slowga on its 1st turn, Graviga on its 2nd turn, and Southern Cross on its 3rd turn. In each phase, it always follows Southern Cross with Spellbind and AOE Thundaga with ST Thundaga; in Very Weak phase, it will use Breath of God on the 2nd turn after using Southern Cross (the turn after Spellbind, if it follows a Southern Cross).
