Corrupted Wisps are found almost everywhere that are hostile and spawn at night. They are more powerful than the regular Wisps.
The look exactily like a normal Wisp : green, flying, cubeoid, and leave a yellow, green, or (occasionally) black trail behind them as they move.
The Corrupted wisp only has one attack: a direct tackle that deals a respectable amount of damage and knockback. However, it can only move in a straight line following the player, and can be dealt with as easily as a normal wisp.
