Imperial Agents in SWTOR can become one of two advanced classes at level 10, an Operative (DPS / Healing Class) or a Sniper (Ranged DPS). The Operative is a ranged DPS/Healing class with light armor. Operatives have three trees to choose talents from: Medicine (Healing tree), Concealment (DPS tree) and Lethality (a shared DPS tree shared with the Sniper Class).
