From Hero's Guide by JD Wiker and Rodney Thompson.

Effect: Instead of making two separate Force power checks, a Jedi may expend some additional energy to split the effects of a power between two targets. If damage dice or bonuses are involved, they are split as well, in any manner of the Jedi's choosing. Powers that can be split include Accelerate Another's Healing, Force Lightning, and Affect Mind.

To use this power, the Jedi must take a +5 to the difficulties of the power and make an Easy stamina check, +5 for every additional use of the power, -5 per hour wihtout using, stacking with other special powers. This power may be used more than once on a single skill use, therefore increasing the difficulty by +10, +15 or more and making the stamina difficulty go to Easy+5, Easy+10 or more. If the Jedi fails the check all Force powers have their difficulty doubled and the Jedi is considered fatigued until they can rest.

To learn this power, the Jedi must spend 10cp and posess Alter at 3D or above. This is a very rare power for Jedi to teach.
