Confuses your opponents by flipping their controls.
— In-game description, Sonic Forces: Speed Battle
The Illusion Mine is a Trap Item that appears in Sonic Forces: Speed Battle. When used, it will place energy cube chunks that can block the opponents' way.
The Illusion Mines take the form of a cluster of small crimson energy cubes.
In gameplay, the Illusion Mine can only be obtained at random from Item Boxes by Espio. As with all other Items, Metal Sonic can also use the Illusion Mine if he uses the Steal Item to steal it from the aforementioned user.
When used, three clusters of energy cubes will be dropped some distance ahead of the user's current location on the lanes that the user is not currently on. Touching an Illusion Mine with a playable character (including the user) will inflict Illusion on them, causing their controls to be reversed. This effect will last for a short amount of time. The Illusion Mines can be upgraded for each individual user by leveling them to levels 4, 10, and 16, increasing the duration of opponents' controls being reversed.
To avoid Illusion Mines, the player must either jump over them or run in between them.
