Particle Spiral Emitter Issue

Problem:

I’m attempting to create a pentagon shape of 5 emitter locations that spiral around and share the velocity of a single particle at it’s center. Let’s call that particle the fireball. I’ve thought of 3 different ways to approach this but each time I bump into a different problem.

Solution 1: Emit particles that use an orbit.
Problem 1: I can’t seem to figure out a means to have all 5 particles present instantly and evenly distributed. I attempted to use a warmup time trick but that created even more problems.

Solution 2: Have 5 different emitters duplicated but use an orbit with a rotation offset of 72 degrees.
Problem 2: There doesn’t seem to be a means to have an offset through orbit.

Solution 3: Off-set the initial location and then rotate around it’s origin.
Problem 3: There doesn’t appear to be a method to do that either. If I use orbit, it still keeps it offset and doesn’t have that beautiful spiral I’m looking for. Rotations don’t seem to factor in it’s initial location before adjustment.

Do I need to use a model to force these locations and rotate that or what? Any help for this newb would be greatly appreciated!
