Predator Form Charge Up:
Be careful when using the Predator Form charge-up on the move because even if done instantly with the R1 + Triangle shortcut on the PlayStation 4 d-pad it can leave your character very vulnerable to get hit by a number of strong attacks.
Activating Predator Form:
The best strategy before activating Predator form is to make sure you space your character a safe distance away from the Aragami but also close enough that the giant mouth from your God Arc can reach.
Entering Burst Mode:
Predator form allows you to absorb the power of the Aragami and enter Burst mode where you will be able to deal more damage, move faster, and get special Aragami bullets. Entering Burst mode is the only way to deal any significant damage to higher level Aragami. To enter Predator form on the PlayStation 4 you press Triangle on the d-pad.
Use gun form to space your way around the monster and get some free hits off while maintaining distance. Make a note of what the Aragami does before the attack lands as this is key to avoiding damage when you approach with Blade form.
