For exemple :
NPC : i need you to do something X
PC : No problem, my friend here can help you with that
Boone : [Speech test failure] Get lost noob
Boone : [Speech test success] Yeah i can do it easily
NPC : Good then! Follow me, ill show you where you can find X or Y whatever...
I've been searching for some time for this one but cannot find any reference.
thanks again
