Combat Powers in Mass Effect 2 are an area of expertise that refers to abilities based around combat, Weapon damage and accuracy. As you level up, you acquire Squad Points that you can spend to improve these aspects of your character. The Powers available to you and your squad are determined by the Class selected in Character Creation.
Power Levels
Except for Unity Power, all other powers can be leveled up to 4 ranks for a total cost of 10 squad points. Regardless of the upgradeable power, each level rank requires the same points as the rank:
- Power Rank 1: Requires 1 Squad Point
- Power Rank 2: Requires 2 Squad Points
- Power Rank 3: Requires 3 Squad Points
- Power Rank 4: Requires 4 Squad Points
Once a Power is upgraded to Rank 4, players need to choose between two final evolutions of that Power. Once you have chosen an evolution, you can not change it back.
