Best Pins for Phasaurus Rex (Boss)

Jealous Rage Kinesis	Gorgeous Gemstone Stone	AkaFuji Blaze Fire	Freestyle Launcher Ice

Affinity Weakness to Ice

The Phasaurus Rex's attacks are all powerful, close-range attacks, so it's best to attack it from long-range. The Phasaurus Rex has an Affinity weakness to Ice Pins, so having a long-range Ice Pin like Freestyle Launcher is highly recommended.

Other Long Range Pins

Gorgeous Gemstone is recommended because it doesn't miss and has the chance to entomb the Noise. Jealous Rage can also be utilized, as it deals powerful damage but is slow to charge up, but that's fine in this case due to the Phasaurus Rex being slow as well. AkaFuji Blaze can be used to deal extra damage by burning the target.

Tips & Strategies for Beating Phasaurus Rex (Boss)

★ Strategy Checklist ★
Go far when tail flashes red Defeat frog Noise first

Go Far When it Signals Attack

The Phasaurus Rex's main attacks are powerful but easy to dodge from a distance. The tail flashes red to signal a tail swing, so when it does, immediately exit its vicinity, as to not take heavy damage. Additionally, dodge sideways when it charges forward, so that it doesn't eat and knock your teammate out of battle.

Defeat Frog Noise First

The Phasaurus Rex initially is accompanied by 6 Frog Noise. If left unattended, these frogs can become a nuisance that change the course of the battle via disrupting your targeting or knocking you into the path of the dinosaur. Defeat these Frog Noise first, while avoiding attacks from the Phasaurus Rex.
