Ninja Trick
Kinetic Blast: A ninja with this trick can create a small energy orb to us as a deadly projectile. This works like the Kineticist's simple blast, using the ninja's level as the kineticist level. Upon selection, the ninja picks one element, and this cannot be changed. Using this ability uses up 1 Ki point per blast.
This trick can be selected multiple times, selecting a different element each time.
Master Trick
Kinetic Talent: A ninja with this master trick learns a Kineticist's wild talent. The ninja must meet the talent's prerequisites, using his ninja level as his kinetist level, along with having the right element per his Kinetic Blast trick. Using this trick uses up a number of Ki points equal to the number of burn points required, in addition of the Ki point used for the blast, if used in conjunction. The ninja must have the Kinetic Blast trick before selecting this trick.
This trick can be selected multiple times, selecting a different talent each time.
Basically, I want to give the ninja a more mystical feel by giving it the ability to learn the Kineticist's simple blast and talent. However, I wished to balance it by having it use Ki points instead of a true at-will ability with no cost.
How does it fare balance-wise?
