Parallel Quests (PQ) | Introduction DB: Xenoverse Guide

You can begin the quest by talking to the robot at the Offline Parallel Quests stand.

Parallel Quests (PQ) become available after the first Time Patrol quest. They get unlocked as you progress in the main story, by completing previous quests or talking to an NPC. The quests can be completed many times, so it's a great way to earn money, experience and unique items. The amount of money and items you'll get depends on the challenge and how you complete it (what rank you get). You'll get some items every time, some for completing additional requirements, others are random.

You'll receive a notification when you collect materials

What's important - you can also find materials used for crafting, dragon balls and unique items of high value. Materials can be found on every arena by using your Scouter. Dragon balls and unique items can be acquired after fights against Time Patrollers. You'll find them in most challenges divided into arenas, after you clear one and unlock the portal to the next one. Use the Scouter and see if there is a Patroller nearby. Approach and challenge him. If you win, you'll receive a reward. It will remain in your equipment only if you complete the whole challenge.
