Psi-Infusion
Great to get your mana back. Its important to stay as long as possible on the field.

Healing Ward
Gives you the best output in this tier.

Khala's Embrace
If you wanna go more DPS you can choose "Static Charge" but i personally use this talent to save a bit mana.

Force Wall
I use this talent for splitting the enemy group or blocking the wall.

Scryer
Gives you more sight and mobility

Resonation
A very small but helpful "slow". you make also more dmg with your psi storm.

Storm Shield
Also a good talent against bursts and dps peaks. On close maps and if you feel easy with the Force Wall, you can choose Force Barrier.
