Space Skills

Being comparable to talents and talent trees of other MMORPGs, Skills improve existing abilities and/or grant passive bonuses by spending points on them. Skills have a direct influence on the overall strengths of your character and your bridge officers' space abilities, and, along with your traits and Captain Specializations, are a key to adapting your character to your play style. Additionally, purchasing a certain number of skills in a specific career, along with ground skills, will also unlock the option to craft new Training Manuals for your Bridge Officers, granting them higher ranks of abilities.

Skills are separated into space and ground skills. Space skills are divided into "Tactical", "Engineering", and "Science" columns. Additionally, there are five tiers of space skills, from Lieutenant at the top, to Admiral at the bottom. While space points 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 tier of the skill tree. Ground skills consist of only one group and have no rank restriction.


Space

There are a total of 90 Space Skills. Players receive a total 46 Space Points, with the first point gained starting at level 5.
