The Skill Design is the best Uridium bought design that not only have a passive bonus, but a special capability with a cool down. Currently, there is only one skill design available. That's for the Vengeance ship.
The current skill design cost 250,000 Uridium.
For the Vengeance:
- The Goliath used to have skill designs too, but now they are separate ships.
- For a short period of time on April 19, 2012, all Goliath skill designs were made so they could only be bought with real money or obtained through booty boxes. This however was quickly switched back after few hours due to a large negative response from the DarkOrbit community.
