Farming Dragon Balls

Much like in DBXV 1, the main way of getting Dragon Balls is by defeating Time Patrollers in PQ and looking for the "Got Key Item" notification. In this game however, you fight Time Patrollers in groups of 3, which while making the battle harder, gives you more chances to snag a Dragon Ball.

In my personal experience PQ 4 and PQ 19 are the easiest quests to grind for getting Dragon Balls. PQ 4 is full of easily killable enemies where after their defeat, a Time Patroller Squad has a chance to spawn in the area. PQ 19's enemies are a little bit harder, but the Time Patroller Squad has a chance to spawn as soon as you start the quest. (Almost always there) Defeat them and keep an eye out for the "Got Key Item" pop up. If you get it, complete the quest as normal, otherwise retry and start again.
