Not sure what you mean exactly, There are some wings in the visual tab called 'Heaven's Might' that can be attatched to the character's hands and give a huge fire effect.
Or Do you mean going to raw tab > digest > visual_equipment > clicking the three dots (collection) > and editing the particle effect to be fire?
