Occultist implements and schools are super natural abilities. The resonance powers are generally supernatural (Su) abilities but most the focus powers are spell like abilities (Sp) with a few exceptions. However, this makes little sense for a number of the abilities.
For example Mind Barrier, Energy Shield, Sudden Insight, Danger Sight and Counterstrike. All these abilities seem to be melee focused (some more than others). But if used in melee they would incur AOO's and require concentration checks.
For example an occultist gets hit in melee and uses counter strike to hit an enemy back. Since its an Sp the enemy gets an attack of opportunity, interrupts the action, hits the occultist AGAIN and the occultist most likely loses the use of the ability. Does not seem like this was the intention. A lot of these feel a lot more like a Su than an Sp. If true this would make a lot of these powers poor to practically useless.
