Electric Orb Pattern

• You will see Blue or Purple orbs around. These orbs will follow Diregent. If she absorb the orb, she will spawn lighting around her, thus interrupting the fight.
• You and another member will also assigned a color. If you touch the orb that match our color, you get 2% attack bonus (not sure the amount of stacks you can get). You will also decrease the Neutralization gauge too ??? (not sure though). So make sure you collect the matching color orbs.

Laser Pattern

• She fires a laser across the map, and the laser start to follow the player. The duration is quite long and can travel very fast if you're far away from Diregent. It's best if you run close to her and slowly move so you have plenty of safe zone.

Other Simple Patterns

(Credit to KDnF Caster)

• The electric ball bounces 2 times when it hits the edge of the map. It will tell you where it bounce to by the red lines.

• Here's another ball pattern. Here you see multiple balls bouncing up and down. Again, avoid the red area.

• Grab pattern, she charge toward and grab you. You will see the red line where she's charging.

• Rotating laser, pretty simple, start at one place and run away from it.

• Following lighting, the orb follows you, and it leave lighting strikes where it goes.

• Circular lighting strikes, here she fires lighting around her. Again, pretty simple.

Berserk Pattern

• She creates a shield in the center. The size of this shield varies depending on the number of electric orbs absorbed by her before the pattern triggered.

• If there is a shield surrounding the her, it means that the shield is at its maximum size, and the damage received by her is reduced by 33%. When the shield is at its minimum size, damage to her is increased by 240%. 

• When you attack inside the sphere, you can damage her but will expand the sphere. When you attack outside, you can't damage her but will shrink the sphere.
• When the casting bar is complete, if the size of the shield increases to the maximum, it inflicts damage to the entire map. If not at max size, anything inside the sphere will take damage.
• In the example GIFs below, the top is fail pattern where the sphere is at its maximum size. And in the bottom GIF is success pattern.

• In this pattern, a strategy is one party member with the strongest damage continuously damage outside the sphere while the other weaker party members damage Diregent from the inside, what way you can decrease the size while dealing damage at the same time. By the time the cast bar is complete, don't forget to run outside so you don't take damage.
