Forspoken's combat is about unleashing magic and stringing spells together to defeat your foes and move through the battlefield. Each spell you cast will create a different effect and unleash destructive power on your enemies.
The PlayStation YouTube channel uploaded a deep dive into the magical combat of Forspoken and the various spells at her disposal. Magic is broken up into different types based on color, with Purple representing earth magic, Red representing Fire magic, and then Blue and Green, which likely represent water and air magic.
Each type of magic offers various offensive, defensive, or supportive spells. Combining these spells allows you to defeat foes and provide shielding and healing to Frey. Mastering these will make combat flow and turn you into a powerful sorcerer.
With so many varied uses of magic, both in and out of combat, you can create powerful combos and cater your playstyle however you want. You can also further upgrade spells to make them more powerful and enhance your combat prowess.
