Bonuses are only applied if you're wearing your dropsuit.

Hahaha.

Efficacy for mods and core skills for the suits.

probably a troll post but hey..

any skill that raises efficiency in a module or item add the + % bonus to the item.. so if you add skill points into say assault rifle efficiency you then get a % damage bonus per level. so your gun does more damage

if you put it into say engineering or electronic for suits you would then get a increase in the amount of power grid or CPU available to fit modules. that way you have more PG or CPU to fit better equipment.

for other equipment it reduces the requirements to fit the item, or makes the item work better.

the way to look at it is.. once you figure out what role you like to play, you then place skill points into areas that improve your stats for that play style.

like to play a assaulter... then you skill into gun and suit of choice, shields or armor skills for better survivability depending on race. etc.

You aren't that stupid....
