有 两次机会可以获得 奖杯，一个是在Virmire， 说服wrex 的时候，另外一次是游戏很结尾的时候 对战saren 的时候，charm或者intimidate 的数值高点 都不难拿到啊

Charm and Intimidate are your tools for wheedling extra money, services, and/or information out of people. Charm corresponds with Paragon (blue, top-left dialogue) and Intimidate with Renegade (red, bottom-left dialogue), although either option isn't exclusive to its respective morality. Both are skills you can attribute points to in the squad screen.

To get this trophy you'll need to have most or all of your available spaces in each skill filled. It doesn't matter which you use as either one will get you the trophy, but you'll need to have more or less mastered the skill.

Once you've done that, there are two opportunities to earn this trophy:

1.On Virmire, once you've arrived at the STG base, you're informed about the nature of Saren's research at the base. Wrex disagrees vehemently with the suggested approach everyone else has to dealing with it, and so everyone fears a violent stand-off. Once he storms away, talk to Ashley and Kaidan. Tell Ash not to interfere before you go over and talk to Wrex. Use either Charm or Intimidate dialogue options whenever a morality check appears on the left side of your options  and eventually he'll stand down and reaffirm his loyalty to you. Congratulations, you just unlocked a trophy AND saved Wrex's life. NOTE: if you complete Wrex: Family Armor prior to Virmire, you won't need Charm/Intimidate to convince him, though you'll still get the trophy.                    

 2 .Your other opportunity is at the very end of the game during your final confrontation with Saren. He'll launch into a diatribe on your continued pursuit of him, and just like a good Bond villain he'll try to convince you of his righteousness. Again, you need to use the Charm or Intimidate options whenever they appear as choices on the left side of your options. Eventually you'll break through Saren's indoctrination and help soothe him, at which point he'll shoot himself and spare you a fight. Trophy unlocked.
