There are 3 major character stats (Mastery, Presence, and Endurance) plus Expertise for PvP. On your character sheet, you can mouse over the stat and it gives you a decent summary of what the stat does. (More melee damage, increase effectiveness of your companion, etc.)
But there are 9 other stats that you find on various armor stats or abilities. But there aren't all listed directly as a stat on the character page.
For example, Accuracy is, but only if you switch to the correct drop-option and you're a class that can use it. If the below stats aren't listed in any of the drop-downs on your character page, does that mean that can't help your class at all and should be ignored completely?
What do the following stats do for your character?
