Killing Leo-Shung Lung
When on the quest where you have to repel Leo Shung Lung have a person stand on a bridge and the other attack this makes it 89% easeyer to kill it. (Note: this may only work 2% of the time and you need 4 people G-class that have compleated EVERY quest in the whole entire game took me long enough to fiure it out. like 1 year!)
