Description: You have developed a potent technique that utilizes your control over the elements and your inner ki.

Prerequisites: Sense Elements, Ki Power

Your shugenja and ninja levels stack for the purpose of determining the maximum radius and number of uses per day of your sense elements ability. For example, a 1st-level shugenja/4th-level ninja could use sense elements four times per day and up to a maximum of 25 feet.

Your shugenja and ninja levels also stack for the purpose of determining your AC bonus as well as the size of your ki pool. For example, a 4th-level shugenja/6th-level ninja gains a +2 bonus to her AC when unarmored and can use her ki powers a number of times per day equal to 5 (half the sum of her ninja and shugenja levels) + her Wisdom bonus (if any).

Special

If you use one of the elemental ninja variant class features (from Dragon #354) the element chosen for your ninja class must match your shugenja element focus.
