my friend has it and i dont, why? what did i do wrong? is there a site that gives you a guide on getting self abilities?
As already stated, these are science ship abilities.
Phaser class weaponry has a chance ( a really small one) to knock out a random sub system, just like the science skill. Only you don't get to pick which one, or when it happens.
That's the best you'll get unless you buy a science ship.
