FIRST STEP (Tactile Psychokinesis): Booker is able to project and manipulate a field of telekinetic energy to his immediate area and objects that he touches. Projecting a weapon requires that a physical 'base' be used, and be in his grasp at all times (eg. using a piece of rebar as a basis for a PK bat). At this stage, the field barely extends beyond being a thin skin-like layer. Able to be shattered with moderate or elongated bouts of force. Can lift as much as your average hard-labor worker at maximal effort.

SECOND STEP (Extended Psychokinetic Projection): At this step in progression, Booker is able to project his abilities in the form of simple constructs. Usually extensions of his body-parts, such as fists and feet. Barriers and shield-walls become possible. His range of influence increases up to 5m and lifting ability increases to around a competitive strongman at maximal effort.

THIRD STEP (Ego Boost): The range and potency of Booker's psychokinesis increases significantly, lending to enhanced physical attributes and stronger constructs. Complexity is still limited, so simple constructs must be utilised but he no longer requires an object to be the 'base'. His barriers become able to withstand much harsher treatment before being shattered and range increases to 10m. Booker gains the potential to lift beyond human capabilities at maximal effort, around a ton above his head before risking damage.

FOURTH STEP (Manifest Ego): Booker's ability peaks at being able to manifest a projection of his own psyche, literally his ego. The projection possesses a personality somewhat, but mostly its there to lend extra sets of fists to the combat equation. Complexity is still limited, but potency accelerates phenomenally, turning Booker into a psychokinetic powerhouse. Strength beyond strength as he becomes able to lift 2.5 tons and throw it about with some effort. Construct range remains unchanged, instead trading in for being able to manifest his 'ego'.

LIMITATIONS: In addition to those already listed, Booker's abilities are limited by the effort needed to multi-task both a personal barrier and supercharging his physical actions. When he is throwing a punch or jumping in for a mighty kick, he is more open to retaliation or a counter than ever. To be caught off guard is a potential end to his combat. Likewise for holding up a barrier, he can either strike or he can guard. He cannot do both at once. Additionally, both his constructs and his barriers, personal or otherwise, are subject to being shattered or completely bypassed if battered hard enough or for long enough. Shattering or throwing out too much PK energy can lead to exhaustion and other side-effects such as reduced strength, slowed reflexes, drowsiness and if pushed hard enough, a complete inability to use his powers for an indeterminate time.

WEAKNESSES:Booker's constructs and concentration both can be disrupted by outside factors. One of the major contributors is loud, grating or otherwise distracting/harmful noises. High-pitched whining and feedback from speakers are his personal worst nightmares, able to disrupt or dismiss his power entirely if loud enough. A lot of Booker's power comes from movement and extending from his own body, and as such, being bound, trapped or having his movement otherwise debilitated severely limits his options as to how he can utilize his abilities. Heat and electrical activity also weaken his powers due to the effects they have on molecules and their local atmosphere. Vibration caused by heat can cause his constructs to destabilize, whereas there seems to be a strange nullifying effect when they come into contact with electricity.
