Searching for Enemies
You can do a Search even when you don't have a scouter. This will give you the locations of hidden items, gates, and enemies. Locking on to the target while on Search mode will allow you to view even more detailed information.
Searching for Items
There are material items hidden in some stages. Searching them will tag their location and the spot will be marked with an exclamation point. Stand on the spot and press Circle to gather the material. Some materials are found inside rocks or boulders. You have to destroy them with Ki Blasts so you can gather them. Take note that you'll only find generic materials here; rarer drops are acquired by defeating random Time Patrollers that appear on certain missions.
Transition Gates
Every location in PQs have interconnecting gates. They'll only unlock after completing objectives in the current location, like defeating the targets. To use this, lock on the gate, get near enough, then press Circle.
Parallel Quest Review
You can check valuable information in your current PQ by pressing the right DPAD. You can also see the connected locations, quest conditions, and obtained items or skills.
Interruptions
Sometimes, there will be instances that new enemies appear after meeting some requirements (like defeating the main targets in the shortest time possible). Most of the time, these new enemies count toward your evaluation at the end of the quest, and gives you a chance to have a better rank or get an material or key item from them. Fortunately, new supporters will arrive the same way.
Support characters
As you go through the main stories and complete parallel quests, more characters will be unlocked. Before heading out on a PQ, you can select up to two Support characters. You can also use one of the original characters instead of your custom fighter.
Reviving Allies
In some quests, when a player's HP is depleted, it's game over. On some quests however, your allies can revive you. You can also do the same for them. Even when down, characters can provide assistance by locking on to one of their teammates. The assists they perform will depend on the character's unique Attributes.
