Companion Crew Skill Bonuses
This page is a quick short guide that will go over every Crew Skill bonus that each classes' companion's have. The guide will be broken down via Republic and Empire than further by each class. A few important notes of information, you shouldn't pick your class based on what Crew Skill your companions can do best, sure it's a nice help but they won't make or break the game for you. Another thing is you can not change what your companion's specialize in. What you see is what you get.
As for your final and probably most common question, what do these extra bonus' even do? Depending on what type of bonus it is, will determine what it does. For example some are something like +10 Slicing and another would be +1 Slicing Crit Chance. The first one of +10 will decrease the chance of failing a mission as well as allow you to gather more higher level items in the wild (good for slackers and those who want a wee bit of a head start). The second one, the crit chance, increases the chance of critting on a mission and receiving something really good.
