This article contains information that no longer applies to the current version of Star Trek Online. It is provided only for historical purposes.

Being comparable to talents and talent trees of other MMORPGs, Skills improve existing abilities and/or grant passive bonuses by spending skill points Experience Point icon on them . Skills have a direct influence on the overall strengths of your character and, along with your traits and Captain Specializations, are a key to adapting your character to your play style. Additionally, some skills also unlock the option to craft new Training Manuals for your Bridge Officers, granting them higher ranks of abilities.

Skills are separated into space & ground skills. Space skills are subgrouped into "Tactical Systems", "Engineering Systems", and "Science and Operation Systems". Ground skills consist of only one career path-specific group ("Tactical/Engineering/Science Officer"). Additionally, there are five columns of skills, from Lieutenant on the left, to Admiral on the right. While skill points Experience Point icon can be immediately spent on skills as they are earned via gameplay, you must hold the required player rank in order to access the next column of the skill tree.

Upgrade levels[ | ]

Each skill has 9 upgrade levels whose skill point costs depend on the rank (i.e., column) of the skill:

  • 1,000 Experience Point icon for Lieutenant
  • 1,500 Experience Point icon for Faction FederationFaction Klingon Lt. Commander / Faction Romulan Republic Centurion
  • 2,000 Experience Point icon for Faction FederationFaction Klingon Commander / Faction Romulan Republic Subcommander
  • 2,500 Experience Point icon for Faction FederationFaction Klingon Captain / Faction Romulan Republic Commander
  • 3,000 Experience Point icon for Faction FederationFaction Romulan Republic Admiral / Faction KlingonGeneral

At upgrade level 9, some skills also unlock the option to craft Training Manuals for Bridge Officers. While players continue to earn skill points indefinitely, the amount spendable in the skill tree is capped at 366,000 Experience Point icon, which is reached at rank Vice Admiral/Lieutenant General (level 50). A maximum of 300,000 Experience Point icon can be assigned to space skills, as at least 66,000 Experience Point icon must go into ground skills. The bonus granted per level diminishes (shown below), i.e., the first three upgrade levels grant +18 bonus each, the second three +10 each, and the last three only +5 each (3x18 + 3x10 + 3x5 = 99 bonus):


Skill point bonus

The absolute improvement a bonus increment grants depends on each individual skill. Starship Energy- and Projectile Weapon Specialization, for instance, both grant ~0.02% critical hit chance and ~0.25% critical severity per bonus increment for their respective weapon type. Starship Weapon- and Shield Performance on the other hand, both grant 0.1% power increase per bonus increment for their respective systems. The exact absolute bonuses for most other skills are not well known and have never been disclosed by the developers.
