Mass Effect 2 Power Durations and Cooldowns

Mass Effect 2 Powers Analysis

The table below lists power durations and power cooldowns.
In Mass Effect 2, Cooldowns affect ALL powers you have -- that is, you cannot use another power until the cooldown has finished. Therefore,
  • If you are trying to set up a combo, you need to look at whether the power duration will expire before your power cooldown is complete so that you can throw out another power.
    • Example: Pull 1 has a Cooldown of 3.00 and a Duration of 5.00. Therefore, you have a 2.00 second window to use another power, such as Charge or Warp (plus the time it takes for the effect to reach the target).
    • Example: Adrenaline Rush 1 has a Cooldown of 5.00 seconds and a Duration of 5.00 seconds. You can therefore be constantly under Adrenaline Rush.
    • Note that some powers have a cooldown that only starts AFTER the power has expired (e.g., Tactical Cloak, Shadow Strike).
  • If you are using powers, a longer cooldown means you are less likely to use the power for offense than support. A long cooldown means during that period, you are more likely to switch to a weapon to continue your offense, or take advantage of it to perform some other tactical action such as retreating or repositioning.
  • Notice the Biotics are very fast, both for Shepard and the Squad. You can almost use them back to back once you start reducing the cooldown.
See the very bottom of this post for the career bonuses to duration and cooldown.

Career Modifiers:
Basically, the differences in cooldown between level 4 class options are virtually irrelevant as the difference is typically a split second for powers with the common 6-second cooldown.
Duration extension is a more complex issue because it helps you chain powers and has secondary not-easily-quantifiable benefits that are highly situational.
  • Adept - Bastion - Cooldown -20%, Duration +15%
  • Adept - Nemesis - Cooldown -20%
  • Engineer - Mechanic - Cooldown -20%, Duration +15%
  • Engineer - Demolisher - Cooldown -20%
