Assault grid won't matter for this, since modifiers just multiply each other. In other words, you should only be looking at the part which is affected - in this case, elemental attack. That's anything between 180% to 255% with double Jack Frost/Tiamat. Add 10% for double Reiki.

I did some speculative maths earlier. No, Tiamat doesn't blow Reiki out of the water.
