yup. Also, summoners will be of the Soul-Born race, which is humans infused with residual magic that allows a direct connection between them and another object or being. Nothing changes, 'cept you get the choice of a couple of new Feats and an ability called 'focus element'
Focus Element: The Soul-Born is able to focus a single element into their body for one of the following effects equal to their Constitution Modifier: Energy Resistance, Extra point of damage on melee attacks of that element, or transferring that element to another Soul-Born to give them a temporary bonus of their choice, able to stack elements in the same body. Otherwise, the limitation of a Focus Element is one focused element without outside interference. Focusing and Discharging a single element takes a swift action.
Energy Blast: Requirements (Soul-Born race, Con 13) Your character gains a ranged touch attack at 30 ft that deals 1d4(+Con Mod) damage of the currently focused element, or 1d6(+Con Mod) points of damage if the focused element is discharged with the attack. This Feat can be taken multiple times, each adding on 10 ft to the range of the tack.
There's a melee version of Energy Blast, which is Element Eruption. Same deal, but it can be infused into a weapon melee attack if the element is also discharged.
