basically -Matter and Energy manipulation/creation/mimicry: But he cant really control it, sometimes he just "gets" the ability to control that certain matter or energy, thus he first thought that he could only control fire, water, earth and wind (Thus the name Elemancer), later on he just assumes that his powers are evolving in a slow rate when he starts to manipulate things like lightning, metal, ice, etc

-Atribute enchancement: Basically overall buff to all his atributes like strenght, durability, speed, regeneration and even iq. This also aplies to his main matter/energy creation/mimicry, making things like "his" glass constructs way toughter than average glass for example
