Overview[ | ]

Science Skill 2 R1

Control Expertise is a Lt. Commander Science skill that is available to all players once at least 5 skill points have been spent. This skill increases the effectiveness of Control Effects (listed below) that you use while increasing the resistance to those effects. Purchasing it allows you to also purchase Improved Control Expertise and/or Control Amplification if you choose. With Improved Control Expertise, you gain a total of 50% effectiveness toward your control effects and 100 control resistance, though you may further increase your Control Expertise substantially using various items and abilities (listed further below).

How Control Expertise affects abilities depends on the type:

  • Confuse, Disable and Placate abilities will have their duration extended.
  • Hold, Pull and Repel abilities will have their magnitude enhanced.
  • Flight Speed and Turn Rate debuffs will either have a set duration and have their magnitude increased, or a set magnitude and will have their duration increased.

Note that for the purposes of Control Effects, Disable refers to the entire ship being disabled. Effects that only disable a single susbsytem—Weapons, Shields, Engines, Auxiliary, or Cloaking devices—are considered Drain Effects and have their duration affected by the Drain Expertise skill instead.
