This spell may be cast upon the Wizard himself or any single friendly character within 12" of him, no line of sight is required. The spell can only be cast on a model with a unit strength of 1 (it won't work on a mounted model or a model riding in a chariot, for example), even if engaged in close combat. If successfully cast, the model can make a normal flight move of up to 20", which may be a charge (the charged unit gets its normal charge reactions). The model can even fly out of close combat if desired, but in this case it cannot charge.
