I have an emission for a jet flame for a 4 sided pyramid but it just looks solid or like glass. How can I remove the IOR value and have an emitting transparent shader for a jet flame?

If this is not possible in Eevee, how could I do it, softening the edges etc?

You will have to mix the final shader with a transparent shader and use fresnel node as factor(fac) value, then you can use fresnel's ior value or a color ramp for controlling smoothness and area to be cut.(Switch color ramp to B-spline for smoothest transition you can have.)

Perhaps you could try use alpha mask to make some parts transparent . Or decrease pyramid size and increase emission to match original. There are probably better solutions tho
