Is there any sure shot methodology to get the charm/intimidate option to be available in mass effect 3?
For instance,
in Priority : Tuchanka, i had to lose Mordin Solus because i didnt have a suitable charm/intimidate decision.
And here, it has been stated that :
Shepard may also have Charm and Intimidate options available. If so, Mordin agrees to delay the genophage cure until after the Reaper threat has passed, and to become a War Asset at the Crucible project in the meantime
I would like to know what i should do to get these in my decision tree. Thank you.
