If you want to do a different method or a lazy method in getting this achievement and you don't want to do the long, boring, normal grind for this achievement.
Then pull out your turbo controller and do the following:
- pick a class that has or have this skill obtainable
- when you have this skill available to use, go to the Citadel and face a Transport Terminal (make sure to target the little blue circle on it) and make sure it's safe (away from enemies)
- during normal gameplay hold the "RB" button
- highlight "Throw" then press "X" (Map Skill) to assign it to your "RB" button
- let go of the "RB" button
- set the "RB" button on turbo on your controller
- rubber band the "RB" button down (make sure you are still facing blue circle of Terminal)
- then watch TV, go on the internet, go to sleep
, go to the bathroom, go eat, or go to the bathroom and eat.
You can just let your turbo controller and rubber band to cast and recast the skill for you.
In the mean while do your chores, do your fun homework, or go to work and come back later to get your cheevo!
