Basic
This comes standard with any Starclanner and is readily accessible energy that they can draw upon from nature, from artificial sources and even from themselves if need be but it leaves them immensely weak if they use the third method. It can be used to do many varieties of attacks and other things in combat like Transmutation of objects, making fields?etc. It is commonly reffered to as Excess in the StarClan tongue as it is frowned upon to use this very often, but in extreme cases it is let slide especially in fights.
Hensou
This involves pulling in energy from nature and turning that energy into a form in which it can be utilized safely and efficiently to take down most foes easily by simply redirecting their attacks back at them akin to a reflexive shield.
Keneros
This is a versatile form of power use among the StarClanners and also a mysterious form as few prefer to use it over Hensou or Excess but still it is available. This actually involves viewing the energy around you as strands, and using those strands to do various things such as teleport, open portals, shoot fire?etc.
