Anyone know how to unlock underground lake? Also: For anyone dragon ball/specific skill hunting. Dragon Balls: When the TP Shows up, I suggest not just spamming them with ultimates. I did it and kept getting material items . I used strictly combos/meteor rush and 1 super/1 Ultimate and got a dragon ball 2 times in a row (4 star and 7 star). Skills: I played PQ 5 like 60 times to get "I'm the strongest on earth" and could not get it. I finally got SSJ Gohan and used him for the first time in PQ. I went SSJ2 3x in the quest and used less Ultimates and got the last hits on Vegeta both times you Vs him in that quest. In the next 6 or 7 PQ 5 I got "I'm the strongest on earth" 2 more times. Not sure if it definitely means anything, but who knows. Pretty coincidental if you ask me.
