Yes, all talents are persistent effects unless the requirements are stated. Ex. Induction in the Deception tree reads as: Increases the critical strike damage dealt by Maul by [15 / 30]%. In addition, Thrash, Assassinate and Voltaic Slash have a [50 / 100]% chance to grant Induction while Surging Charge is active, reducing the Force cost of your next Shock by 25%. Stacks up to 2 times. You will gain a persistent [15 / 30]% critical damage on Maul, but only gain the Induction buff, which reduces the cost of Shock, while Surging Charge is active.
