*** Spoiler - click to reveal ***The easiest way to achieve this trophy is to proceed to the final boss battle. In it, you'll find that occasionally Lofty will have a gauge that can be charged by holding X. He might stop allowing you to for a short period of time before allowing you to charge again. Once you fill it up you will become awakened like when you pick up a gold ball. While this does count towards the trophy, there is a catch. Even after getting 50 awakenings, you still have to pick up a gold ball for the trophy to unlock. Easy enough to do, just go to Faraway Forest's later floors and block enemy attacks until Lofty eventually gives you one.
You may need to repeat the final boss a few times, just remember you can skip all dialogue and cutscenes by holding Triangle.
