Acacia and Shadow Mirage are regular enemies who appear exclusively in the Japanese version of the 1993 Sega Mega Drive science fiction RPG "Phantasy Star IV: Sennenki no Owari Ni" (ファンタシースター 千年紀の終りに).
Acacia appears in the Cavern of the Sacred Sword, the area holding Elysdeon below Esper Mansion. Like the other enemy that appears here, Phantom, Acacia is an extremely weak monster who reflects the cavern's status as a gathering place of good spirits. They possess only one basic attack with which they can damage the heroes. One strike from Chaz can easily finish this enemy in any battle.
Shadmirage, which is likely shortened from Shadow Mirage due to name length restrictions, is a color variation of the Acacia. They appear only in the late areas of the Edge, the game's final dungeon. Much stronger than their light aligned cousins, these creatures are servants of evil like others in this area. Shadow Mirages have two special attacks. Shadowbind, which is shared with the third Dark Force and Chaos Sorcerers, reduces the hero party's agility. The unique Star Dust attack, shown below, is a powerful energy attack that blasts the entire party of heroes.
