Mirage (ability)

Mirage, also known as Image, Twin, Target Dummy, Mirror, and Shadewalker is a recurring ability in the Final Fantasy series. It is a Ninjutsu spell, and acts similar to the spell Blink, creating two illusory copies of the caster to render them immune to the next two physical attacks targeted at them, each attack instead dispelling one of the copies.

Edge learns Mirage at Level 38. It has a casting time of 0 and costs 6 MP to cast.

Final Fantasy IV -Interlude-
Edge retains Mirage, which functions identically to how it does in the base game.

Edge and Tsukinowa can cast Mirage, which works the same as it did in the original game. Edge learns Mirage at Level 32, while Tsukinowa knows the ability innately.

Final Fantasy V
The Ninja can use Image as a command ability, learned at Job level 2. Image works the same as Blink, creating two copies of the user to dodge attacks. Due to a minor glitch, once one of the copies has vanished, using Image a second time will create a third copy, allowing the user to dodge three attacks.

The Shadow Scroll acts as a substitute for the command. Throwing the Shadow Edge is one of only three ways to gain Blink status, the other two being the Fenrir summon and the Mirage Vest.
